For a short duration (10 seconds), very high current drain (1 - 2 Amp), but still maintaining low self-discharge rate (70% or more within 1 year).
For example, Rechargeable AA NiCd / NiMh great for high current but mediocre self discharge. Non-rechargeable Alkaline / Lithium AA has virtually no self discharge, but does not withstand very high current drain.
The perfect battery is supposedly Rechargeable Lithium-Ion (which is used in new generation cordless power tools (drills, etc), but IS AA SIZE (PENLITE) RECHARGEABLE BATTERY EXIST, YET?
Otherwise what’s best the AA alternative?
I heard Sanyo’s Eneloop isn’t good if being used for very high current, is this correct?

I purchased a 12V DeWalt Cordless Driver for someone and I’d like to know how this drill charges. I bought it used and it only has the 12V battery pack on the bottom of the drill. The drill is fully charged and has tons of power. Is there an adaptor or charger that I need to purchase as well?
