Overall just okay, see update review
21 December 2018
Amazon says these batteries gonna keep the charge 70% even after a year ! The batteries I received were manufactured in 04-2018. I received them on 3rd week Dec-2018. They are 8 months old battery. Not bad.
When I put all of them into Panasonic BQ-CC 55 (It's best aa/aaa battery charger) for charging, it indicating red led light and after 15-20 seconds the light tunrs yellow. That means they were only around 20% charged. They loose 80% charge in 8 months !
Will update my review soon about how they perform.
It's overall good batteries. Original Branded Manufacturers never charge the batteries fully, that's why after opening the box the new batteries won't have that much juice inside them. After few charge and use cycles the batteries will get their best capacity.
These amazon ones are very good and cost effective too. Yes they are holding charge for pretty long time.After a full charge it's 2 weeks going on and i haven't charge them yet, using on my led torch (XML - T6).
Never-ever use any old fashioned dumb charger to charge any rechargeable battery. Always use a smart charger that can charge each battery individually and can cut charge automatically when the battery is full.
I have seen many bad reviews for many good branded batteries. I am sure that 99% of the reviewers didn't use a smart charger, and they probably charged the batteries for 8-10 hours out of the pack, hence overcharging and damaging the batteries, they might have gave bad reviews. Because in old chargers you never gonna know when the battery is full and how much charge is left before charging & it will never cut the charge automatically when the battery is full.
