Eneloop Panasonic BK-4HCCA10FA pro AAA High-Capacity Ni-MH Pre-Charged Rechargeable Batteries, 10-Battery Pack

These are the best lithium rechargeable batteries on the market! I have dozens and dozens of them. They have high capacity, hold their charge while and last for a very long time. Expensive but in the long run, they are economical.

So at first i bought the white Eneloops to give them a try but was very disappointed that they didnt hold a charge for very long and drained quickly. Ok, lets try to the better, black batteries, which have proven to be marginally better than the white ones. I'm sure if they are used in very low draw devices then they're ok to use but in high draw devices, these batteries do not last long. For example, i use a IR gun to monitor the temp of my woodstove and for the past 5 months ive been using the original batteries that came with it but when i switched them out to the fully charges black Eneloops, they drained very quickly. So the cheap original batteries lasted 5 months and the black eneloops lasted about a week!!! I am done with rechargeable batteries because they obviously do not have enough storage capacity.

billed as professional and longer lasting, with a price tag to match. only offers a slight improvement over cheaper batteries

Literally the day of the return window already had a battery go bad. Won’t charge. Tried in the Panasonic chargers they suggest, and in another charger. Said error. When I first found the battery was not charging I felt it and it felt hot enough to burn me and I was afraid it was gonna explode.

Be aware these are AAA batteries, not AA.
