LLOYTRON NiMH Rechargeable AccuPower Batteries/AAA Size / 550mAh / 4 Pack - B014

These batteries are cheap so I wasn't expecting the full advertised performance. I put the batteries through two refresh cycles, draining them each time over a few hours in a high powered torch, then charging at 500ma using a smart charger. I got 730, 750, 772 and 830mAh capacities for each of the batteries. This is close to what you would expect from a standard set of 800mAh AAAs, but at half the price. Don't expect the batteries to hold their charge for long, but when they arrived they were 80% charged.I'll be using these regularly in an 800 lumen torch, since I don't want to put too much wear on my more expensive batteries, and I will post back if there is any major degradation in performance over the weeks (So if I don't you can assume they are fine)edit: Apr 2020, batteries are fine, still close to 700mah after many dozens of cycles

I've charged these batteries up and tested the rating. It comes in at 950 average.These do have a slow discharge rate. However. I've shoved them into my BT 8500 cordless phone. Left the phone off the Base to see how long it will last. 4/5 days max before I stuck the phone back on the charging base.

Be very careful, these batteries as indicated on the packaging don't come charged, which means held long enough in store will never charge (Like Mine). Attempted to charge using my standard electronic Battery charger , and it showed a error, on two of the 4 batteries. The second two charged but really quickly telling me there something wrong with the internal metals that hold the charge, wont be buying this make , or from the seller again.

I purchased these back in May and am now editing to update, these are simply the best rechargeable batteries I have purchased, I use them in my Xbox One controller and have had many rechargeable types before but they either don’t hold a good charge or start off holding a good charge then gradually fail.I have been using these on a daily basis for 2 hours plus a day and one charge normally lasts 7-10 days depending on how long I play for, I have seen no decrease in the length of time they last in 6 months of use so I would highly recommend these.

I bought these about 4 months ago and the 2 that i tested have a capaicty of 759 and 788 mah (advertised at 1100 mah). These were tested simultaneously with 2 other batteries (different brand) which were bought about 2 years ago at advertised capacity of 850 mah and those showed capacity of 919 and 906 respectively (I have a micro-processor controlled charger which can do clever things). So I leave it to you to figure out how good these are
