Are these batteries any good? Better than the Energizer one they had offered before? Saw these at the warehouse, same price as online.

Now made in China. Garbage. The old Japanese ones were Eneloop.

It's just not what it was in the past. So not really a deal. Inflation and effects from the pandemic have made this economy volatile, and unpredictable.

Not true! The AA should be about 2,650 mAh and AAA 800mAh (see amazon review). If it indeed the case, Duracell AA is a better deal than Enerloop.

What @Mushypizza said is correct, it's printed on the top back corner of the packaging.

1300 looks like the capacity after 1 hour charge for AA batteries. When charged in full, AA should be at least 2450 mAh.

See image attached to post #14. 1300mAh is the actual capacity of the AA's in this kit.

The Amazon ones I bought stopped recharging (fail blink) in less than 1 yr - very disappointing.
did I have bad luck/batch?
