Schumacher Electric 12V Battery Charger & 50A Engine Starter SC1305A — 3-in-1, 10A Boost

The Schumacher SC1305 is a compact 3-in-1 12V battery solution that starts engines with 50A, delivers a 10A boost, and charges/maintains batteries up to 6A–2A with smart, multi-stage control.

Built for garages, workshops, and owners of seasonal vehicles, the SC1305 combines an engine starter, a faster boost charge, and a trickle maintainer in one rugged metal housing. It handles common 12V battery types—standard flooded, AGM, and LiFePO4—using automatic charge stages and safety features so you can revive, recharge, and preserve batteries without guesswork.

How does the SC1305 help when my vehicle won't start?

The unit offers a 50-amp engine start mode designed to provide the surge current needed to crank most 12V car and light truck engines. Use the heavy-duty color-coded clamps and starter cables to connect quickly; built-in reverse polarity protection reduces the risk from incorrect hook-ups. This is a fast, portable option for jump-starting stalled vehicles without relying on another car.

• 50A engine start output for quick jump-starts
• Heavy-duty clamps and booster cables included
• Reverse polarity protection to prevent connection errors

What charging and maintenance modes are available?

The SC1305 provides multi-level charging: a 10A boost for faster replenishing, plus 6A and 2A modes for full charging and long-term maintenance. The charger shifts automatically through charge stages to protect battery health and minimize manual adjustments. A trickle mode keeps seasonal vehicles, stored equipment, or rarely used machines at safe charge without overcharging.

• 10A boost for quicker charge recovery
