The Harbor Freight NiMH rechargeable AA batteries do test out at 2800 ma-hr.
The 9 volt rechargeable NiMH battery is 8.4 volts which is better than the typical 7.2 volts of some MiMH or NiCad batteries.

I prefer to keep rechargeable batteries in flashlights, radios and instruments because they do not leak corrosive materials.

With the 20% discount coupon the HF NiMH batteries are good value for less used stuff.

I have many Eneloop rechargeables for highly used stuff and the 1200+ recharges they do seem to be capable of make them valuable.
Today the Panasonic Eneloops are made in mainland China but
Fujitsu still runs the original Japanese eneloop factory.
