Schumacher Electric 1.5A Car Battery Charger and Maintainer, 3-in-1 Solution, for 6V/12V Power Sport, Automotive, and Marine Batteries, SC1355.

What It Is

The Schumacher SC1355 is a 1.5-amp automatic battery charger, maintainer, and desulfator designed for 6V and 12V lead-acid batteries. It’s ideal for maintaining the battery in riding mowers, lawn tractors, zero-turn mowers, and other small-engine equipment during storage or off-season.

Fitment & Compatibility

• Battery voltage: Works with both 6V and 12V lead-acid batteries (flooded, AGM, gel, and deep-cycle). Does not support lithium batteries.
• Battery size: Best for batteries from 5–50 amp-hours (typical for riding mowers, ATVs, motorcycles, and marine starting batteries).
• Connector: Comes with clamps and a ring terminal harness (hard-wire to battery). Check that your battery terminals are clean and accessible for either connection type.
• No deck or engine fitment needed – this charger connects directly to the battery, not to the mower’s electrical system.

Key Things to Know

• Fully automatic: Once connected, it monitors and maintains voltage without overcharging. No manual settings to adjust.
• Desulfator function: Helps recover and extend the life of sulfated batteries – useful for batteries that sit unused for months.
• Low amp output (1.5A): Not designed to jump-start a dead battery. It will slowly charge a deeply discharged battery, but expect 12+ hours for a full charge on a 30Ah battery.
• Weather resistance: Not fully waterproof. Keep the unit dry or under cover during outdoor use.

Should You Buy It

If you own a riding mower, tractor, or zero-turn that sits idle for weeks or months, this charger is a solid, affordable pick. It’s easy to use, works on both 6V and 12V batteries, and the desulfator feature adds real value for battery longevity. Skip it if you need a fast-charge or a jump-starter – this is for slow, steady maintenance only.
