I bought an 8 pack from Wally World for appx $17 about 2 weeks ago.
FYI.... The previous versions offered last year were 2100 mAh.

I've never lost a single NiMH battery in 5 years of use.
Call it luck or just old fashion TLC. <g>

As to self discharge...
Ambient temp is a most important variable.
20 to 45% loss in 30 days is typical for NiMH cells according to

Ta-ta....

I too rarely lost one, until I started using the 30 minute charger,
occasionally. But I know that isn't particularly good for them!<g>

Same brand of Energizer.
They use to be 2100 mAh before morphing to 2300.

Last year I bought some Nexcell 2.2Ah AA's off Ebay for $.99 each (about
$1.15 with shipping). I expect higher capacity cells could be had for the
same price now.

I haven't lost a cell for a few years, since I started using a good
microprocessor controlled charger. Cheap chargers will either undercharge
them or make them die young, and cheap fast chargers are even worse.
