Energizer Rechargeable Battery AA Pack, Recharge Power Plus, 16 Pack, Rechargeable Battery AA -

Simply the best rechargeable batteries I've ever bought.I use these for wireless vocal mics in our band, they last ages - they will do more than one gig if I forget to charge them and they NEVER run out in a gig. Used them at a festive recently and only swapped them out after 5hrs to make sure they didn't stop mid performance but they were still going, just me being cautious.

I happen to have a very sophisticated charger that tells me a lot about these batteries, I purchased a box of 16 and tested them all. First the internal resistance was very low and extremely consistant at 15mR for them all. Low internal resistance helps to get the last bit of charge out and helps supply high current draw devices.Next I put the batteries on a test cycle where they are charged->discharged->recharged to ascertain what capacity each was able to hold. I have Chinese lithium's where they outrightly lie about the specification eg 5000mAh 18650's that only hold an average of 800mAh for the entire pack so I was not expecting great things about the claimed 2000mAh of these NiMH Energizer AA cells. Out of the sixteen there was only one below par (and I will re-test that), they all had over 2100mAh capacity, some were nearly 2300mAh, the average was around 2200mAh. So there you have it. Coupled with the fact that these batteries were the cheapest to buy and have some recycled content (not a primary selling point for me) the batteries are a no-brainer. Small number of folk that have given poor reviews here ought to get a proper charger.

Great bit of equipment to have with Blink cameras

Obviously they are rechargeable but still it’s a bit sort change to have only 20% charge in them from new.

Used in wildlife camara. Perfect for the job.

Fantastic product These are the best make of rechargable batteries I have ever had. When used they seem to last forever. Better than expected. Delivered on time
