Schumacher Electric 1.5A Battery Charger & Maintainer — 6V/12V Auto-Detect, Desulfation for AGM/Deep-Cycle

The Schumacher Electric SC1355 is a compact 1.5A charger and maintainer that automatically detects 6V or 12V batteries to charge, maintain, and desulfate standard, AGM, and deep-cycle batteries.

If you keep vehicles or equipment that sit for weeks or months—classic cars, motorcycles, ATVs, lawn tractors, or seasonal boats—the SC1355 is designed to give you reliable starts without the hassle of frequent battery replacements. This 3-in-1 unit combines a steady 1.5-amp charge rate with multi-stage charging control and a desulfation routine to help recover and preserve battery capacity. Its automatic voltage detection and safety features make it easy for non-experts to use while offering practical protections for the workshop.

How does the SC1355 simplify charging for different battery types?

The SC1355 recognizes battery voltage automatically and adjusts charging behavior accordingly, so you don’t need to select modes manually. It supports standard flooded, AGM, and deep-cycle batteries for both 6V and 12V systems, and applies a controlled multi-stage charge to protect battery chemistry.

• Automatic detection of 6V or 12V batteries on hookup
• Compatible with standard, AGM, and deep-cycle batteries
• Multi-stage charging minimizes overcharge and stress
• 1.5A output suited for maintenance and slow recharges

Can this unit help revive older or sulfated batteries?

The SC1355 includes a desulfation feature intended to reduce sulfate buildup that limits battery performance. While results vary by battery condition, this mode can sometimes restore partial capacity to neglected batteries and extend usable life.

• Desulfation routine targets sulfate crystals on plates
• Designed to improve performance of lightly to moderately sulfated batteries
• Works best as part of regular maintenance rather than guaranteed recovery
• Safe to leave connected during long-term trickle maintenance

Is the SC1355 safe and user-friendly for home garages?

Yes—safety and simplicity guided the SC1355 design. It offers reverse polarity protection, automatic voltage recognition, and smart trickle charge so you can connect the unit and leave it to maintain batteries without constant monitoring.

• Reverse polarity protection prevents accidental clamp damage
• Smart trickle charging avoids overcharging during long storage
• Quick-connect clamps and ring terminals make setup fast
• 6-foot power cord and 5-foot booster leads provide good reach

What comes in the box and who benefits most from this charger?

The SC1355 ships ready to use with quick-connect battery clamps, ring connectors, and a user manual. It’s built for hobbyists, DIY mechanics, and anyone maintaining seasonal or infrequently used vehicles who wants an affordable, low-maintenance solution.

• Includes SC1355 unit, quick-connect clamps, ring connectors, and manual
• Compact footprint suits crowded workbenches and small garages
• Ideal for classic cars, motorcycles, lawn and garden equipment, ATVs, and boats

Who is this for: The Schumacher SC1355 fits owners who prefer a simple, reliable charger that protects battery health over time without technical setup—budget-conscious drivers, weekend mechanics, and homeowners who need dependable maintenance charging and occasional reconditioning to avoid premature battery replacement.
