Schumacher's Automatic Battery Charger/Engine Starter utilizes a microprocessor to automatically adjust the amperage rate to charge and maintain batteries, with multi-stage charging for added precision, safety, and battery life. Charge rates include: 150 Amp engine start, for quick starting; 55 Amp rapid charge, for larger batteries; 20 Amp fast charge, for regular charging needs; 2 Amp trickle charge, for charging small batteries and warming large ones; and float-mode monitoring, to automatically maintain optimum battery charge. Features include: battery and alternator tester to help diagnose electrical system problems and battery state, reverse hook-up protection to ensure the charger will not operate if clamps are reversed on battery terminals, digital display and LED lights to indicate when the battery is fully charged, and timer control with automatic shut-off.
This charger is incredible, most of these full chargers are dummy models that have at most a timer, if you're lucky. This has timer functions AND a fully automatic mode just like the small Schumacher smart chargers.
The 150 amp mode is well thought out not to destroy the charger and protect the user from themselves, here's how it works: You turn it to the 150A setting after hooking it to your vehicle as described. The charger will engage the 150A current once it detects the car turning over (voltage drop) and will continue to apply that current for 10 seconds (the display shows the count down). After the first application, the charger will do a 180 second count down to allow the unit to cool, and will then be ready for another application as needed.
All of this capability in a fairly lightweight, sub-100 dollar model? You can't ask for more than that in my opinion. This charger is awesome!
