100 Amp engine start
2 amp slow and 1230 amp charge rates
Charges AGM, deep cycle, gel cell, SLA and standard batteries

This speedcharge charger has computer control to enhance the charge rate and it also monitors the battery condition to insure that the battery is not overcharged. With this charger, your batteries will be fully charged quicker than with conventional chargers. This charger is designed for use with 6-volt and 12-volt, deep cycle, gel cell and absorbed glass mat batteries.

The Schumacher SC-10030A SpeedCharge Battery Charger/Maintainer with 100-amp Engine Start is a versatile, fast and efficient battery charger/maintainer suitable for use with a variety of 6-volt and 12-volt lead-acid battery types used in everything from tractors, motorcycles, stand-up PWCs and snowmobiles, to those found in cars, trucks, SUVs and RVs. It features fully automatic microprocessor control; automatic multi-stage charging allowing for ease of use; two charge rates: 2-amp and 12<>30-amp; and the ability to choose the type of battery being charged. Additional features include 100-amps of built-in AC powered jumpstarter power, along with battery tester and alternator tester functionality.

Faster, Smarter and Safer 6-Volt and 12-Volt Charging

By combining conventional battery charging technology with state-of-the-art circuitry, the Schumacher SC-10030A SpeedCharge Battery Charger/Maintainer offers versatility, speed of charging and convenience rarely seen in a battery charger. The charger features an easy-to-use and monitor touchpad on which two output current rates are selectable: 2-amp and 12<>30-amp. The touchpad also allows for the selection of battery type being charged: 12-volt regular automotive, 12-volt deep-cycle, 12-volt AGM or gel cell and 6-volt regular batteries; and provides data percentages of a full charge that is stored. All these features and data are heightened by the prescence of a powerful microprocessor at the heart of the unit.

The microprocessor of the Schumacher SC-10030A SpeedCharge Automatic Charger and Maintainer monitors the attached battery’s voltage level from the moment it is connected, using this ever-changing data to improve the charging system’s multi-stage charging cycle. Multi-stage charging allows a battery charger to automatically cycle, between a variety of charging phases including desulfation, bulk charging, absorption, monitoring, float mode and a minimal drip charge maintain mode when a connected battery again falls below a certain set level. The microprocessor collected data is especially important in this cycle in that with it the SC-10030A can more accurately measure the charging needs of a connected battery, resulting in quicker charge times and a lessened chance of damage due to overcharging.

2-Amp and 12<>30-Amp Charging Rates

An additional key to the speed with which the Schumacher SC-10030A SpeedCharge Automatic Charger and Maintainer works is its 2 available charging rates: 2-amp and 12<>30-amp. By allowing users to choose the best rate for the right battery type and charging needed the SC-10030A is better able to supply exactly the right level of charge, at the right time in the charging cycle to get quick results and maintain connected batteries at theie proper levels. Details on the three available charging rates include:

  • 12<>30-amp Fast Charge – Self-adjusting, variable charge rates for everyday charging needs and maintaining your battery in peak condition. Charges and automatically desulfates and restores car, truck, RV, farm equipment, AGM, gel cell and deep-cycle batteries.
  • 2-amp Slow Charge – A gentle trickle charge for charging and maintaining small batteries; charges motorcycle, ATV, snowmobile and lawn tractor batteries.

Valuable Additional Features

In addition to serving as a battery charger the Schumacher SC-10030A also contains several automotive diagnostic tools that come in handy in any garage. These include: an AC powered battery jumpstarter, a built-in battery tester and an built-in alternator tester.

An AC Powered Jumpstarter

Your Schumacher SC-10030A battery charger can be used to jump start your vehicle using the built-in “engine start” feature if the battery is low. This feature is capable of delivering up to 100-amps of jumpstarting power via your household AC current.

A Built-In Battery Tester

Schumacher SC-10030A battery charger has a built-in battery tester that displays either an accurate battery voltage or an estimate of the battery’s relative charge based on the battery voltage and the Battery Council International scale.

Built-In Alternator Tester

Th built-in alternator tester displays either an accurate alternator voltage or an estimate of the alternator’s relative output compared to normal alternators. The Alternator % values displayed should be taken as general reference, not precise diagnosis.
