For serious car aficionados and home mechanics, a reliable manual wheel charger is a mandatory piece of garage equipment. While some people prefer an automatic charger, others want total control. For those who want control, the Schumacher SC1633 200 Cranking Amp 12-Volt/24-Volt Manual Timer-Controlled Wheeled Battery Charger and Jump Starter fits the bill. This manual design features a 135-minute timer and manual rate selection switch for precision control over the charging process, which must be monitored. The SC1633 reliably delivers a heavy-duty, 200-amp 12-volt engine start, which is powerful enough to start SUV, truck, and other large engine batteries. The unit’s boost mode will quickly bring deeply discharged batteries back to life with 50-amp 12-volt boost, 25-amp 12-volt boost, and 25-amp 24-volt boost modes. It also features a 10-amp 12-volt charge/maintain mode with enough power to keep batteries charged and healthy. An easy-to-read ammeter provides amps and engine start status. Compatible with most automobile battery types, the SC1633 works with 12-volt and 24-volt standard, AGM, gel, and deep-cycle batteries.
