Style:9V(9.6V) | Size:1-pack The Powerex Precharged MHR9VP Rechargeable NiMH
Battery (9.6V, 230mAh) is a nickel-metal hydride battery compatible with
Powerex's MH-C1090F 10-Bank Charger or MH-C490F Stealth Charger. It is rated
at a voltage of 9.6V and a capacity of 230mAh, with a minimum capacity of
215mAh. It has the ability to outperform a standard 9V battery due to its
slightly higher voltage. The battery is capable of being stored for an
extended period of time and still retaining a full or nearly full charge.
After a year, for instance, it will retain 85% of its capacity. The battery
comes pre-charged. The purchase of an NiMH battery like this one saves you
money, since you won't need to buy endless supplies of non-rechargeable
alkaline batteries.
