Schumacher Electric 700-Watt Power Backup System

Don't waste your time or money

This charger maybe alright if you need to charge a low voltage battery, but for a battery that has been completely discharged, this charger will not turn on and will not charge it. The one i purchased did not work at all on the jump start mode, no leds turned on, nothing. Almost like the switch was not even connected inside the charger.
