Schumacher SP-1 2/4-Amp 6/12-Volt Automatic Battery Charger/Extender Review



Schumacher SP-1 2/4-Amp 6/12-Volt Automatic Battery Charger/Extender Feature

  • Automatic charger for 6- and 12- volt batteries
  • Microprocessor-controlled technology
  • Automatically determines if the battery is 6 or 12 volts
  • Quick Connect Harness easily changes between battery clamp and ring terminals
  • Ideal for power sport vehicles, motorcycles and small cars

The Schumacher SP1 is a fully automatic microprocessor controlled automatic battery charger that maintains both 6V and 12V batteries, keeping them at full charge using float-mode monitoring. SP1 is perfect for charging small batteries, but is also great for maintaining small and large batteries kept in storage, such as those for motorcycles, classic cars, RVs, and boats.

Ideal for motorcycle winterization, maintenance, or storage
Ideal for Motorcycle Maintenance and Storage
The 2-amp charger and maintainer automatically switches from Full Charge to Float-Mode monitoring. While the SP1 is great for charging nearly all battery types, it's especially ideal for maintaining the charge on winterized or stored motorcycles. Use the 50 amp clamps, 12 volt accessory plug, or permanently attach the ring connectors--great for hard-to-reach motorcycle batteries.

Fully Automatic Operation

The SP1 automatically switches from Continuous Charge to Float-Mode Monitoring, which allows the charger to maintain the battery when fully charged. The SP1 resumes continuous charging when the battery becomes discharged.

Auto Voltage Detection

The SP1's Auto Voltage Detection automatically selects battery voltage (6V or 12V) and charges properly depending on the type of battery connected.

LED Indicators

LED lights on the SP1 indicate the connected battery's status, including Power, Charging Battery, and Battery Charged.

Reverse Hookup Protection

Reverse hookup protection safeguards car battery, computer, and other Instant Power uses from damage if the cables are connected to the wrong terminals. The charger will cease to operate when clamps are reversed or touched together.
