Battery Monitor does it all!
Charge up a battery and maintain the charge with just one unit. Its built in 3 step charge allows for charging up to 90% capacity at 2.7amps, then switching to a timer controlled charge at 14.7 volts to bring the battery to full capacity and finally holds it there indefinitely with a float charge.
Indicator lights show each charge step.
12 volt battery only.
