The battery locomotive was very flexible up to the limit of its ampere-hour capacity
Edison Minit-Charger notes how its sequential system can recharge - return ampere-hour capacity
to a depleted battery - at a charge current level up to four times higher than conventional chargers.
Before shipping, Panasonic tests each battery thoroughly for its electrical continuity, rated Ampere-hour capacity
and 100 percent jar-to-cover seal leak air tightness to ensure quality and performance in the field.
To store this power he suggested two 6-volt batteries, each with a 220 ampere-hour capacity
, hooked in series to generate 12 volts.
