User questions & answers

Question:	Are these batteries approved to go on airplanes
Answer:	Yes. Lithium batteries must be in carry on bags, they cannot be in checked bags.
Question:	how do I get in touch directly with a problem with the item
Answer:	Through your Amazon account. Problem? Return it
Question:	What is the voltage of these batteries? they don't work in my handheld mic. non-lithium aa energizer batteries do work in the mic
Answer:	They are rated at a minimum of 1.5 volts, the same as alkaline batteries of the same size. I tested a lithium Energizer AA out of a fresh pack and it registered 1.85 volts on a digital multi meter. I am surprised that you are having difficulty with the lithium. If you are not getting at least 1.5 volts then the battery is bad, no matter what its chemistry.
Question:	Anyone know if there is a difference between the "advanced" lithium and the "ultimate" lithium?? Other than price
Answer:	I thought it would be marketing as well. So I looked in a leading consumer review Magazine and there is apparently a difference. They rated the "ultimate" A few points higher than the "advanced" and for the two tests that they use, one a flashlight test and the other a toy test, the "ultimate" received "excellent" on both tests, while the "advanced" Received "excellent" on the flashlight test and a "good" on the toy test. So I assume the lithium ultimate version lasted longer on the run down test for the toy, which is going to draw energy more inconsistently than a flashlight. If I find a product is burning through batteries faster than expected, I will usually try lithiums. More often than not, the improvement in run time is substantial

User questions & answers

Question:	are they made in china
Answer:	Mine (bought in June '13) said made in Singapore on batteries & were marked "Not for retail trade", came in unmarked (aside from amazon label and label saying "20 pack AA Lithium Batteries) plastic box.
Question:	What is the shelf life of these batteries
Answer:	These batteries are excellent LONG LASTING batteries . Just purchased some with an expiration date of 2035 . One may think they are a bit expensive, but I don't think so, because of their longevity, and supreme performance.

User questions & answers

Question:	If batteries have a manufacture date over 1 year, can they be returned
Answer:	That's up to Amazon's return policies. I'm not sure that's an important issue with rechargable lithium anyway. But of course, the newer the better.
Question:	What is the cut off voltage? Does the internal circuit prevent voltage dropping below 1.5v
Answer:	Yes, this battery cuts off at 1.5 V, but it holds that voltage much longer than other batteries in my experience. I had some devices that just stopped working when voltage dropped below 1.5 with NiMH batteries, but those same NiMH batteries just kept working for a relatively long time in other devices that could tolerate a lower voltage. The Kentli batteries are great for those devices that won't work with a lower voltage, I'm getting much longer times between recharges than with the NiMH batteries.
Question:	Can these be charged in the Nitecore smart charger
Answer:	No. I would not try. Kentli is not selling what are considered 'standard' lithium ion batteries of 3.7 volts. I seriously doubt the Nitecore could charge them correctly. Adding one of the Kentli chargers to a battery order is cheap and they work fine. NOTE: We might be surprised and the Nitecore charges the same way as the Kentli charger. But nothing I know of indicates that to be the case. Therefore, better safe than start a lithium ion battery fire. Such fires can be very nasty.
Question:	I see each battery is rated at "3000mWh" (at 1.5v). How many mAh does that convert to
Answer:	Volts x Amps = Watts. In this case: (mWh)/(V) = (mAh) = 2000 mAh A simple online converter: https://www.convert-formula.com/mwh-mah

• Real High 3200mWh Capacity-- 3200mWh lithium AA rechargeable batteries, highly using performance for 6 hours, better than NI-MH batteries 3 hours definitely, 1.5V constant output. (Not compatible with Apple mouse, keyboard and Blink Camera Series )
• 2 Hours Full Charged-- Deleepow rechargeable AA lithium battery can be full charged within 2 hours. Made of grade A+ cells insided, using without worries. (Deleepow 1.5V li-ion rechargeable batteries can only be charged with Deleepow Battery Charger, please don't use the charger for batteries of different brand or types of Li-ion, Ni-MH, Alkaline,etc)
• Low Self-Discharge & No Memory-- AA rechargeable batteries is low self-discharge, they can maintain 80% of capacity after being stored 1 year, it will not damage the internal materials of battery.
• 1 Equals to 1500-- Rechargeable AA batteries can be recharged 1500 times, ideal disposal Alkaline batteries substitutes, saving your money, reducing waste, everyone should do his bit for the protection of the environment.
• Shopping without Worries-- Your satisfaction is our first believe, so please contact us anytime when you have any “problem with order", we will help you to solve it as soon as possible.

User questions & answers

Question:	The capacity of they claim is 3200mAh, but with battery tester measure only holds around 2000mAh. Buyer beware
Answer:	Capacity is 3200 milliwatts hour, not 3200 milliampers hour. AA batteries with 3200 mAh do not exist... Yet.
Question:	Is it compatible with all chargers
Answer:	You should buy Deleepow's charger to avoid battery damage. It is a 4AA USB charger. The batteries I purchased are Lithium Ion batteries. You do not want to overheat these batteries. If you spend $25 for (4)AA + charger or $20 for (4)AA only, buy the charger option. The batteries pictured are Nickel Metal Hydride. These are typically 1.2 Volts vs. 1.5 Volts per battery. I would not buy 1.2V batteries for critical applications.
Question:	Can this charger charge 1 or 2 batteries or does it have to charge all 4 at the same time in order to work
Answer:	You do not need to charge 4 at a time. 1 is fine, any amount is fine.
Question:	can i use this charger for Nicd batteries
Answer:	No you can't and you cannot use other chargers to charge these batteries as well.

User questions & answers

Question:	These batteries for the rechargeable ones for an every day hallway light motion detector
Answer:	Energizer Ultimate Lithium batteries are not rechargeable. Although they would probably work well in an AAA-powered motion detector, these batteries must be disposed of (preferebly, recycled) when depleted, and keeping your motion detector powered with these would be expensive. Primary (non-rechargeable) lithium batteries like these are best for infrequently-used devices, especially ones exposed to high or low temperatures, like an emergency flashlight that you keep in your car. You would probably be happier with rechargeable NiMH batteries for a constantly-used device like a motion detector.
Question:	what is the voltage? Are these lithium rechargeable
Answer:	Actually they are rechargeable, but they are not meant to be. You shouldn't use a regular charger, and certainly do NOT use a lithium charger. You should know what you're doing and do some experiments first, then know they aren't going to last either. Normal rechargeable batts don't last anywhere near as long as advertised either, but these will last even less. I haven't experimented with these nearly as much I have with other batt types, but I figure it's worth it to me to get one good charge outta them, then I toss 'em. After a charge I use them like I would alkaline batts, meaning I only put them in things that don't matter, like cheap flashlights etc. I wouldn't rely on it to work after sitting for ten years. It may still work, just saying I'll stick to oem for important stuff and looong shelf life. I can say that so far none of these have leaked out to ruin anything, like alkaline do, recharged or not... If you ask "How do I charge them if not with a regular charger", then I hate to say it but if you have to ask you probably shouldn't try. And most, once they hear how, would be unwilling. If you/anyone is still interested; use low current and be wary of it. Like charge it somewhere it can't hurt anything if things goes south. The worst thing I've ever had happen in decades of messing around with batts is they vent alkaline, or acid depending on the type, and make a mess. So far I've had better luck with Energizer Lithium than any other non-rechargeable batts, but I usually only charge the AA since I use those most. Second most is button cells, specifically 2032 cells of whatever quality brand. Button cell charging started because all the ones I tried had too low of voltage for my car remote. The car would say "batt low" in one to a few days. So I charged them a little, I guess whatever was missing since they were made, and now they last months. The smaller the cell less the charge rate, so you need a multi-tester, resistors, pots/rheostats etc to get it right. For AA I'd est 100mA or less is a good starting point. AAA I guess 50mA. 2032 I rekon 5mA. be certain of polarity and never let the batt get warm. This all applies to alkaline too, if you want to bother with them but may be nice in an emergency, like shtf ;)
Question:	How many mah are in each aaa battery
Answer:	Thank you for reaching out to Energizer. Each battery carries 1250 mAh. For any further information you can reach out to us at [email protected] or can call us at 800-383-7323.
Question:	These batteries get hot when I charge them. Anyone know why
Answer:	You CAN recharge lithium batteries (even if they don't say that they are rechargeable) if you use a charger that SPECIFIES that it can charge LITHIUM batteries. I purposely bought the Opus BC-T3400 (here on Amazon) and it does recharge my lithium batteries without overheating them when set on a lower lever charge rate.

Question:	Are the batteries 9 v or d? your title says d’s but your pictures of a 9 v’s

Question:	Will these charges in a Lithium-ion charging bay
Answer:	Nope... they are not re-chargeable
Question:	Are these batteries new? Or do they arrive with only a year or two left before they expire
Answer:	My batteries say March 22nd. The package says 5 year storage guarantee. I get much more use time than any of the other batteries I’ve used. I use them exclusively for my TENS units.
Question:	what is the good until date
Answer:	I ordered these and received them in June 2019. The expiration date was only 1.5 years away: DEC 2020. Not acceptable for such expensive batteries. And that they are shipping out fresher product six months ago: it tells you that Amazon isn't rotating its stock appropriately--which is their JOB as a product distribution company. All of this to say...don't expect fresh batteries if you order batteries that are sold by and shipped from Amazon. (What a shame...)

User questions & answers

Question:	What is the color of the light? Is it white or yellow
Answer:	The light is white
Question:	How hot is this model
Answer:	if you mean "hot" as cool, I don't know, but it is good looking. If you mean "hot" as hard to get/in demand, I don't know that either. If you mean how "hot" does it run, it's not hot at all. I've had it about 4 months now, on all the time (holding a charge), and I've recharged it once. In none of those times have I felt any heat at all. My plan now is to recharge at the start of every month, easy to remember. When I looked after 2 months, it only had about 30% left, so I'd left it too long. It charged back up again, though, pretty quickly. No heat.
Question:	Is it able to charge from a 220 volt Outlet
Answer:	The other respondents don't know what they are talking about. this charges on 5 volts DC. So if you live in a place with 220 you already have available 220 AC to 5VDC Chargers, in fact most US ones are 110-240 AC to 5VDC. House mains 110-220 VAC to 5VDC, car 12CDC to 5VDC, and of course power banks all output 5VDC. I have scores of chargers around my house from iphones, other phones, powerbanks, etc etc that are 5vdc output and I cant find a single one that isn't BOTH 110-120 and 220-240 input.
Question:	If there is no way to recharge, will this accept regular batteries
Answer:	Hello Briashmad, yes, you can recharge the unit for up to 50,000 hours of rechargeable use. The Lithium Ion battery is top quality and will offer a long life of charging and discharging. On the other hand, no, the unit does not need disposable batteries. Thank you, Tough Light
