Energizer Ultimate Lithium AA Batteries - Pack of 4 Longest Lasting, Leak-Proof Design, for High-Performance Devices

High energy content. Excellent Lithium batteries. Price is worth paying.

These batteries tends to maintain peak performance until most of its capacity and then it will die quickly! Initial voltage were 1.81 volts/ cell. And if you give some rest to these batteries then it will again crank up the voltage to around 1.7 Volts. If you want to charge them then you have to trickle charge them at 20 mA outside!! (Only for experimental results, beware) If you want to buy then use it in medium drain devices for best battery life or if you want performance then you can use it in high drain devices like motors or Cameras 👍 Battery can leak if current limit is high or they heat abruptly! So charge current should as low as that of an led which is 20 Ma. For more details see the internet, and they would take UPTO 6 days to recover outside!! Only experimental trickle charging but with a higher voltage than 1.4 volts! The voltage should be as high as 1.85V for lithium metal or Nizn batteries and trickle charge @10mA only!!! due to the electrolytes being used and to lessen the dendritic growth and get extra capacity atleast some extra!!! It works but risk involved so use it wisely and carefully!!! Thanks 🙏😊💚

It is durable, and we anticipate it will be leakproof.

Very nice orginal product, thanks amazon

These AA batterirs cost about 15 times more than normal alkaline batteries. Naturally, one expects them to last for a comparably more period of usage. But, alas! they just drained out completely after same period as normal cells !!! Feeling cheated.

I’ve always liked Energizer, and since this is a lithium battery, I picked it for my electronic door lock. The idea of being locked out and calling the service guy (with a heavy bill) didn’t sound fun. These batteries are expensive (for me), but they claim not to leak — which is a big plus when your lock costs more than your monthly coffee budget. Also, they’re supposed to last longer, hopefully over a year. Mumbai heat can hit 45 degrees, and my previous alkaline batteries sometimes gave up in protest. Let’s see how long this one lasts. The pack says it’s good till 2050 — if only my patience lasted that long. Worth trying for devices you don’t want to mess with.

An efficient & long-lasting product! Thank you Amazon!

The batteries last a really long time, which is impressive. However, they are quite expensive compared to other options.
