QUESTION: ARE THESE BATTERIES AA? WILL THEY WORK WITH MY CAMERA? IT TAKES 4 AA BATTERIES AND THEY DIE IN ONE DAY. SOOOO FAST. ANY SUGGESTIONS?
• They are close to AA size, but are actually bigger. They are 3.6v batteries, and AA batteries are 1.5v batteries. They aren't interchangeable and probably wouldn't fit. These aren't appropriate to use in your camera. If you are using regular alkaline batteries (non-rechargeable), then that would explain why your batteries die so quickly. NiMH rechargeable batteries last much longer. You should be able to find some good high-capacity ones on Amazon somewhere.
• These will work in some cameras but these are 3.7 volt instead of the standard 1.5 volt. I use the Eveready Lithium 1.5 AA batteries and they do quite well. I only use Ultrifire batteries in my Cree flashlights.
• this are like AA, but the volts are 3.7, your camera works with normal AA batteries 1.5 volts, 4x1.5=6 volts, but if you put 4 of this of this, 4x3.7=14.8 volts, your camera blows!!, you should buy rechargable 1.2v AA batteries at 2500 or 2800mah, if you put a 110v. bulb into a 220v. outlet the bulb blows!!, you always have to respect the specified volts, but if you want that the batteries don't die to soon you should buy it with more mah, normal AA batteries are almost like 1000mah or less
• No they are not AA and although they are the same size do not under any circumstances use these on any gear that are not designed for these batteries. AAs are 1.5 volts and when used in series the voltage is increased by the same amount for each battery added so 2 AAs have 3v etc. These 14500 are 3.7v each so instead of having 3v on a two battery setup you have 7.4v which is way above the recommended voltage.#ultrafire
QUESTION: ARE THESE BATTERIES PROTECTED OR UNPROTECTED?
• sorry ,this battery no have protected,if you nee have protected we hvae ,but the price is different
• I'm not very happy. I got about 3 charges before the batteries went belly up. I don't know if it was the charger or the batteries. Good luck.
• There is no PCB on the bottom of the battery. And since you asked, of the two I bought, one has already failed. The light on the charger that indicates it's charging the battery, has never worked since it arrived. I find this system to be of inferior quality.
• they are just a battery like all other batteries#ultrafire
QUESTION: I HAVE A MAGLITE MINI PRO LED FLASHLIGHT-ALUMINUM ALLOY-SP2P09H (226 LUMENS), AND I'M USING DURACELL AAS IN IT. CAN I USE THESE BATTERIES IN IT?
• These batteries are rated at 3.6 volts each. A regular AA is 1.5 volts. I recommend you to use 2 regular Duracell (or similar) rechargeable batteries rated at 1.25 volts each. In a pinch you could use (1) 14500 and a dummy spacer battery, but there is a chance you could damage the LED driver circuit, and if it did work you would have a shortend operating time due to only a 1200 mah rating on the battery ( a single rechargeable AA battery typically has a a 2000 mah rating, or more stored energy). So in short, don't use this battery, use regular AA's or 2 standard rechargeable batteries. Hope this helps. ~ James ~
• Seven and a quarter volts will damage the LED system in a three volt flashlight. When in doubt ask Maglite.
• Guess I should have reminded you of that pesky old warranty thing.
• If the flashlight calls for AAs, you should use AAs. The power of these batteries makes the flashlight unsafe and could result in serious injury.
• I do not have that specific flashlight, so I cannot give a definitive yes or no answer. If the regulator inside the flashlight can handle the increased voltage that these batteries output compared to a standard battery, it should work. They won't last as long as a standard battery or a standard rechargeable battery, and they may not increase the brightness either.
• Yes you can. And it will be about 40% brighter.#ultrafire
QUESTION: DOES THIS CHARGER COME WITH BATTERIES?
• Don't buy this...not a good product. Safety concerns. And yes, I got batteries with mine. Don't waste your money.
• Yes. The charger comes with 2 batteries.
• yes ,is two battery and one Charger
• yes, it with 2x battery and one charger, so you can order it
• Yes, two and you can charge 1 at a time or both at once. It works great, I'm charging 1 battery right now.
• Mine did... but I can't speak to what your order will include. My charger and batteries function just fine. The charge rate is slow, but not so slow it causes concern for me.#ultrafire
QUESTION: CAN THIS BATTERY BE USED IN A ENERGIZER LITHIUM 1AA LED FLASHLIGHT?
• This 14500 rechargeable Li Ion battery can be used in flashlight that requires 3.7 volt AA size battery.
• Yes, it works.
• Curious thing about lithium batteries is that a single cell produces about 3.6 volts so there is really no way for a lithium battery to produce 1 and 1/2 volts like an alkaline battery. So to answer your question, Yes you can use this battery to replace the other lithium battery because it produces the same voltage and is the same size physically.
• If the flashlight is designed for 1.5 volt operation, 3.6 volts will damage the electronics in the bulb prematurely. The last time I answered this question, I refered the gentleman asking to contact the manufacturer on this subject. One can assume the warranty would be voided if you ever wanted to return the damaged light when the bulb went on early vacation. If you have a light that uses this 3.6 volt battery you could use a 1.5 volt battery in it but it would not be as bright.
• No, I don't recommend using a 3.6 volt battery in place of a 1.5 volt battery unless the flashlight specifically says you can. You will burn the LED driver circuit out in most cases.
• Unlikely as the 3.6V battery is slightly larger in size than AA batteries, both in width, and more importantly, in length. It is not a great difference, but most likely enough to make it too large for your flashlight.
• Duplicate please ignore...#ultrafire
QUESTION: WHY ARE RECHARGEABLE BATTERIES FATTER THAN REGULAR BATT
• I don't have a full answer, but the size difference is not related to the fact that they are rechargeable. The i i/2 Volt AA or AAA batteries are no different from Alkaline and others. I think the 3.6Vs were developed for use in appliances and gadgets. Mine are mostly lithium. I am not certain whether that is related to the size difference. Industry experts will be able to respond with greater precision.
• This battery is 1200mAh .bigger than regular battery
• I do not think they are fatter.#ultrafire
QUESTION: CAN I CHARGE 10440 BATTERIES WITH THIS CHARGER?
• I think you need this charger: Trustfire Multifunctional Universal Lithium Ion Rechargeable Battery Charger for CR123A, 16340, 14500, 10400,... because it can accommodate both of the batteries you mentioned. It is $9.98 from Amazon... No I don't work there... See: http://www.amazon.com/s/ref=nb_sb_ss_i_2_5?url=search-alias%3Delectronics&field-keywords=10440%20battery%20and%20charger&sprefix=10440%2Celectronics%2C322 Cut and past this in your address box to get to the charger...
• Voltage would the same. 10440 are a different size though. Not by much. Check the Nitecore Intelligent charger. By this and your done. About $13 and you can charge almost anything. The new model is a great item. A real go to charger.
• I tried to charge my 10440 batteries with the charger and it was not successful. It could be a failure on my part. However, I would buy a charger specifically for the 10440 batteries just to be certain of a proper charge. That's what I did. The charger still charges every other battery I have thrown at it.#ultrafire
QUESTION: ARE THESE AA'S? WILL THEY FIT IN A NERF STRYFE (AA BATTERY TRAY)?
• They are slightly larger than standard AAs but they will fit. Be careful though, because the voltage is over twice as much as standard AAs so it can fry what you put it in if it doesn't have a built in resistor, which can also lead to overheating/fire.
• Yes they work, i don't suggest putting 4 in due to overheating/frying the stryfe, but 2 or 3 and (a) dummy battery(s) should work if you remove the stryfe's voltage limiter :)#ultrafire
QUESTION: THERE'S NO INSTRUCTIONS ON HOW TO CHARGE THIS BATTERIES FOR THE FIRST TIME, ANYBODY HELP??, PLEASE
• Just insert the batteries into the charger OBSERVING PROPER POLARITY (battery + to charger +) and wait until the charger LED goes from red to yellow to green. When the charger LED is green, the battery is fully charged.
• Both batteries go into the charge unit with the negative (flat) end of the battery facing the springs at the top of the charger. When charging for the first time the single led at the top of the unit will glow RED until charging is complete, this may take 8 to 10 hours if cells were fully depleted. Once charged there will be a steady Green light.
• I would do one of two things. Charge them for 24 hours. Or send them back. Mine only lasted about 3 charges. That still put them roughly the price of a good disposable battery, but these are not high quality.
• if you got the batteries and charger from china then its about a two hour charge. take them off the charger when done, dont let them stay on.
• The springs always go to the flat end of the battery. Plug charger into the wall. When the light goes green the batteries are charged.#ultrafire
QUESTION: ARE THESE PROTECTED OR UNPROTECTED? I WAS WONDERING IF THESE HAD OVERCHARGE PROTECTION ON THEM OR ARE THEY UNPROTECTED?
• Yes, they are, most protected batteries show Protected on the fine print on the battery. The charger is smart and will not overcharge an unprotected battery.
• I haven't bought these, but am thinking about it for use with flashlights, but according to the "Worked well, arrived quickly, May 12, 2012" review from "MikeDan", the batteries are protected.#ultrafire
QUESTION: WILL THIS BATTERY WORK IN THRUNITE NEUTRON 2A CREE XM-L T6 FLASHLIGHT 260 LUMEN ?
• The 14500 is the same size as AA batteries and the TruNite specs say it will accept the higher 14500 voltage (and higher). But I don't have the light and therefore can't test that the 14500s work in this light.
• of course it will...you can put anything in this light from cheapo AAs to the hotest rechargeable Li-ions. But why would you want this light? the only thing impressive about it is the fact that it takes any battery that will fit in it / otherwise, there are better lights for the price, and equal lights for less $
• It should, it will just be brighter.
• No. Maximum voltage is 4.2 for this flashlight. This light takes two standard 1.5 volt AA size batteries. You can use regular (2) 1.25 volt rechargeable batteries. Lithiums are about 3.7v. Two of them = 7.4 peak volts. You will overdrive and destroy the LED driver and/or LED within seconds. There are limitations to the way anything is designed/built. If you want more light, read reviews first and purchase a flashlight rated with a much higher lumen output.#ultrafire
QUESTION: DO THESE WORK WITH THE COAST HP1 FOCUSING LED FLASHLIGHT?
• If the coast takes double a batteries it does and the 3.6 volt batteries will make a flashlight way brighter
• Yes, it does.
• yes it is a 14500 1200mAh 3.7v battery with charger
• These batteries 14500 are the same as AA batteries but Rechargeable so check if that item you have works with AA batteries
• yes you can use it in that model
• The flashlight description will tell you if the light works with 14500 batteries.#ultrafire
QUESTION: IS THIS THE SAME AS CR123A
• No. The 14500 is the same physical size as a regular AA battery. The CR123 batteries are fatter and shorter. They are the "photo" batteries you see at your local store. Definitely not interchangeable.
• Nope. They are the same as AA batteries in size, however the voltage is much higher so beware when using these. Make sure ur device can handle 3.7 volts. Cr123 size is 16340 btw. Also know as rcr123a.
• These are not the same as CR123a. These are the same physical size as a "AA" battery - but are 3.7 volt vs. 1.5 volt for a "AA" battery. Be careful what these are used in so as to not accidently damage electronic equipment.
• No these are the same size as a double A but more powerfull
• No. This is AA.#ultrafire
QUESTION: THE ONES IN THIS AD THAT ARE BY GOODFIRE ARE 3.7V. THE ONE THAT IS BY ULTRAFIRE IS 3.6V. WHAT DOES THIS MEAN? WHICH IS BETTER?
• It's just a tenth of a volt so any difference is minimal. Technically the 3.7 are probably better.
• It's just a tenth of a volt so any difference is minimal. Technically the 3.7 are probably better.
• That might be a misprint, my UltraFire batteries are 1200mah 3.7 volt. The UltraFire picture shows 900mah 3.6 volt.#ultrafire
QUESTION: CAN I USE A NORMAL AA BATTERY CHARGER WITH THIS BATTERIES??
• No you cannot, You need a charger that has a voltage higher than the battery. A regular AA charges a little over 2.7 volts, so the Li-ion would take no charge because it is 3.6 volts.In other words you cannot charge a battery unless the charger is rated to charge the type of battery you have, a regular alkaline is 1.5 volts and a li-ion is 3.6 volts.
• I don't think so.. these are more powerful then normal AA batteries
• No AA rechargeable are 1.25 volt these batteries are 3.7 volt I have no idea what would happen to charge at lower voltage.
• I don't believe you can. These batteries take a much higher charge. Just like if you put these batteries in a normal flashlight it will destroy the light.#ultrafire
QUESTION: IF THE BATTERIES NEED TO BE REPLACED WHERE DO WE BUY THEM?
• on Amazon there have some item only sell batteries.
• 14500 3.7v battery
• try searching on E-bay for this item......don't run these batteries all the way down.....i did and now i cant get them to re-charge
• do a search on amazon for batteries and chargers I keep a couple of spares and have them chargeg then rotate them every month or so with use#ultrafire
QUESTION: WILL THIS CHARGER ALSO CHARGE THE 3.7V 18650'S?
• No. 18650 batteries are physically larger than 14500 batteries. The 18650's won't fit in the charger.
• No. They will not fit this charger. Rule of thumb for these types of batteries, first 2 numbers are diameter in mm. Second 2 number are length in mm.
• No. 18650 batteries are physically too large to fit in the charger.
• The 18650 batterie are larger that the 14500, and need a specific charger for them. They are about half-way between a AA and C size battery, the 14500 is an AA size battery.
• No cuz it's too smal. But I don't recommend buying from him cuz it burned out in two days and the batterie are dead and no power in the charger. His seller sucks
• No they are a different size#ultrafire
QUESTION: WILL THAY FIT IN ANY CHARGER OR DOES IT HAVE TO BE AN ULTRA FIRE ONE?
• Any charger that can do 14500 batteries and 3.7 volts
• It has to be ultra fire one or you stand the chance they will not fit
• The battery charger is 3.7v
• Any charger.
• Any charger that can do 14500 batteries and 3.7 volts#ultrafire
QUESTION: ARE THE BATTERIES AA SIZED
• Yes Megan they are AA sized. They work great!
• The ones I purchased were AA size. I wouldn't recommend this brand though. I had one battery fail after just a couple charges.
• The batteries are AA size, but of course, the voltage output from these is different than alkaline.
• The 14500 batteries are the same physical size as a AA battery, but the voltage is more than double (3.6V vs 1.5V).
• yes, double aa batteries will work, but the light won't be as bright.
• They are very close to AA sized but are not interchangeable because they have a higher voltage.
• Yes they are. be sure the device you put them in, can handle the voltage. Lion batts have more than twice the voltage as a standard AA.#ultrafire
QUESTION: WILL THESE BATTERIES WORK ON A VAPORIZOR?
• No AA size
• That would depend on what the vaporizer's operating voltage is! These batteries are 3.6Volts each. In series, the voltage adds!!! Regular AAbatteries are 1.5 volts each
• The voltage is 3.7v
• The voltage is 3.7v#ultrafire
QUESTION: WHAT IS THE CHARGE TIME TO RECHARGE BATTERIES?
• I only have one set of 1200ma batteries. I now only purchase the 2000ma size. But to answer your question, I believe the charge time depends upon how discharged they are but normally it takes me about 3-4 hours. I just plug them into the wall and go on with my computer work and when I stop for a break they are usually done charging. The 2000 ma ones are ~67% more capacity so get those if is convenient. Not much extra cost either. Hope this helps...
• 3 - 4 hours on mine.
• Couple hours. I've never timed it, I just throw them on the charger got out to eat, come back and the light is green.
• these lithium batteries recharge in about two hours. dont overcharge them.#ultrafire
QUESTION: I HAVE A 7W 300LM MINI CREE LED FLASHLIGHT TORCH ADJUSTABLE FOCUS ZOOM LIGHT LAMP. CAN I USE THESE BATTERIES FOR THIS FLASHLIGHT?
• Yes, you can.
• Those are the batteries I use, it is brighter than with regular AA batteries.#ultrafire
QUESTION: ARE THESE THE BATTERIES THAT FIT THE SMALLER ULTRA FIRE FLASHLIGHT (THE MINI CREE). THE FLASHLIGHT IS ABOUT 3 INCHES LONG.
• that is what i have in mine.
• I would try putting a regular 2A battery in the flashlight first and see if that is the size it takes , if it takes that size then yes they will fit. But look at the instructions that came with it to be sure it will work , these batteries cant be used in everything because of their power they can burn circuits out. I have a survival radio that states not to use them because they will burn my circuit board out , so just be carefull with them. :)
• No they are for the bigger flashlights#ultrafire
QUESTION: WILL THE CHARGER STOP CHARGING WHEN THE BATTERIES ARE CHARGED?
• I am not 100% sure, but believe it does. It is not very warm after the charge.
• Yes it will the red charging light will turn green#ultrafire
QUESTION: WILL THESE BATTERIES DAMAGE MY CAMERA?
• Thoroughly read your camera's instructions. Most cameras take a compact, proprietary battery. If your camera specifically states to use these, probably not. Remember, these put out higher current than alkalines and will probably damage anything designed just for alkalines.
• I'm sorry but I can't answer your question. I've only used the batteries in a LED flashlight.
• I have purchased both sizes of batteries at various stength. I put them in a camera, in a remote control, and another unit that I cannot r emembe. stick with the high intensity flashlights. better to be safe with something expensive.#ultrafire
QUESTION: CONFUSING TO ME. DOES THIS COME WITH ONE CHARGER AND TWO BATTERIES AS SHOWN IN THE PICTURE?
• yes, but read my previous review.
• Yes it does.
• yes just like the pic#ultrafire
QUESTION: MY VIDEO CAM USES 2 AA 1.5V SIZE RECHARGEABLE BATTERIES, CAN IT BE REPLACED WITH 2 AA 3.7V RECHARGEABLE BATTERIES WITHOUT ANY DAMAGE TO VEDEO CAM
• hi.customer,not used,2 aa 1.5V is 3V output ,if 2*aa 3.7V the vloatage is 3.7V ,VOLTAGE DIFFERENT
• I doubt you can use these batteries in your video camera. I would say check your manual and see what it says.
• If you do you will burn something out because you will raise the voltage from 3.0 volts to 7.4 volts more than doubling the input.
• Please don't. I don't know what your camera uses for input voltages, but if you get it wrong, you can/will smoke your camera. Too much voltage.#ultrafire
QUESTION: WILL THESE RECHARGE MY IPV4S BATTERIES?
• i dont think so, but they may,, however the nitecore 2 or 4 will, definately worth 20 bucks#ultrafire
QUESTION: WILL THIS CHARGE A SINGLE BATTERY AT A TIME? OR MUST YOU CHARGE IN PAIRS.
• It seems that my charger does charge them one at a time.
• yes, no problems
• I put 1 battery in the charger and the light came on , when i plugged it in the red charge light also came on so i would say yes you can do 1 a time
• It will charge a single battery. However, please don't waste your money on this - the batteries are garbage. I didn't personally have a problem with the charger, but If you scroll through the litany of complaints others did.
• I'm not 100% sure so I don't want to give you wrong information. I can try it later on tonight#ultrafire
QUESTION: WHAT IS THE BATTERY LENGTH?
• Same as AA.
• It is the same size as a "AA" battery.
• 34mm long
