Microprocessor controlled chargers are the latest technology
and are completely automated. They continuously monitor either
the voltage or the temperature of your batteries and are able
to determine precisely when to cease fast charging. They then
switch to trickle charge mode. Batteries in any charge state
can be brought up to full charge in less than 4 hours without
risk of overcharging.
