PANASONIC official data
PANASONIC official data released 1998 on the EV95 Battery guaranteed a minimum of 1000 full deep charge/discharge cycles. Please not these days many lithium manufacturers or the car makers who use them are claiming 3000 chaerge cycles for lithium but this is based on tests that are often as little as 50% discharge. Like so many things nowadays the numbers are not honest. PANASONIC today in making lithium cells since being prohibited from making high density NiMH cells no longer assured full deep discharge cycles above 300.
