AAA Alkaline
Notes:
(a) See notebook 2. I cycled the battery with gradually increasing charges. The Q and E numbers reported here were obtained by overcharging the battery by twice its rated capacity of 0.5 Ah. Not recommended. The battery lost its ability to hold charge on the next cycle when it was fed 1.35 Ah. The battery delivered 0.50 Ah when charged with 0.66 Ah.
(b) Although the energy in this battery is low it has the advantage of being safer for electronics. Alkaline batteries leak after a few years and seriously damage whatever the chemicals touch. Carbon-zinc batteries are "dry" and won't leak.
(c) These batteries are suppose to last 20 years, without leaking.
