The Best Rechargeable Lithium Aa Batteries

[NiMH] Best value you can get in AA batteries, plain and simple

[9.4 x 6 x 1.45"] It's a bit snug, but my rechargeable AA batteries fit in this pouch just fine.

[1x Rechargeable] Best speedlight ever made!!! Namely due to the rechargeable Lithium battery that holds a charge through hundreds of uses.

[8x AA] The Ultimate Lithium AA last a long time!

[Black] 50W is very loud! Lightweight Lithium Ion rechargeable batteries. Very easy to use. I especially like the 10 second built-in memory.

[Ni-Cd, Ni-MH] I purchased this, not for analyzing rechargeable batteries, but for measuring capacity of several different brands of lithium AA batteries. There is a common knockoff of this product that didn't actually work for my use case, but I did use it for charging batteries, and I can say that the user interface of the Powerex is much more intuitive and easier to use. As far as customer service, I emailed Powerex to find out if this would do what I was trying to do, and a representative called me and let me know that while it is not an officially supported use, it would work, which proved to be true. I would definitely buy more products from them after having that experience.

[0.145 lb] ZX800 battery works just fine as do all Coast rechargeable lithium batteries.They offer decent run times and and std discharge while not being used is slow which is a good thing.

[0.095 lb] Coast’s lithium battery ZX450 all batteries that Coast supply are excellent. Reason I say this is because rechargeable lithium batteries sometimes have issues like premature failure. Things like not taking a charge, memory issues, and short run times to name a few. I do handle lion cells as recommended which is important for long life. Coast batteries and my lithium cellular batteries are the only batteries that work as promised regarding rechargeable lithium cells. I expect an a dramatic improvement with rechargeable lithium batteries of all sizes any time.

[0.025 lb] This is my first time purchasing rechargeable Lithium Ion batteries with a built-in USB charging port. That's a very convenient way to charge the battery especially if you forgot the adapter at home.

[0.5 lb] Performance with two disposable lithium batteries is average for the current market, but with the rechargeable battery it easily outshines much bigger devices. I'm impressed
