8 Pack Rechargeable Lithium AA Batteries with Fast Charger, 1.5V High Power 3600mWh Double A Batteries, AA Rechargeable Li-ion Batteries with 2000+ Cycle Times

Absolutely love these! Work just like a lithium battery should. No gradual fade, steady and strong, with a span greater than a top grade alkaline. The same voltage as an alkaline too, at 1.5v each. Even better, they’re rechargeable! Saves you so much money with even better performance and far superior run time life. Recyclable. The recharge cycles are superior to ni cad, more like nimh without the memory effects. Top them off first before the first use. Run down completely. Do this a few times and it will run better each time. 3-4 full cycles and they will be at max capacity and will perform at the best possible.

I recently decided to upgrade my old Gameboy Color with a backlit screen and boy oh boy does it chew through the batteries. This was a MUST and it has worked incredible for me. Just have to remember not to throw out the batteries by accident :)

This is the 2 nd set of batteries. The first set I received and charged. I use them in my door lock. They were great and then I went to replace them and the 4 batteries waiting to be used lost there charge in 30 days. I went to charge them and 1 battery was no longer charging and had never been used.I sent the batteries back for a replacement and the replacement had to charge for 8+ hours. I got tired of waiting and went to bed. In the morning they showed charged. We will see how the replacement set does.In the beginning I was absolutely satisfied with the batteries until it came time for replacement. We will see how these do.

These are great to use on my gas/electric fireplace that requires batteries. If you are sick of buying replacement batteries all the time you might want to look into these. They seem to be a lot better than regular batteries. I have NOT tried these in anything but the electric fireplace though. Anyone using flashlights ECT please add your own comments and reviews.

Giving this 4 stars because these batteries don’t last long and the charge seems to be 2 hours. Do not think batteries are good quality but it works for my sons portable game!

This rechargeable battery system is a game changer. It's super compact, so it doesn't take up much space at all. I can easily toss it in my bag and take it anywhere. Plus, the battery life is amazing, it lasts forever on a single charge. Definitely recommend checking this out!

Perfect worked as it should. I love that the batteries and charging station are part of one package.

One of the batteries does not charge and will have to be replaced. The charger works well.
