Lightweight and fully automatic, this unit combines a simple plug-in design with multi-stage charging and built-in safety features so batteries receive the right voltage and current throughout charging and maintenance cycles.

How will this charger protect my battery from damage?

The SC1299 uses a multi-stage charging algorithm to bring batteries to full capacity and then shift to a low-current maintenance mode that prevents overcharge. It also includes reverse polarity protection and spark-free clamps to reduce connection errors and safety risks.

• Multi-stage charging adapts voltage and current as battery condition changes.
• 0.8A trickle rate keeps long-stored batteries healthy without stressing cells.
• Reverse polarity protection prevents damage if clamps are accidentally reversed.
• Spark-resistant, color-coded clamps make safe connections easier.

Which battery types and vehicles is the SC1299 compatible with?

The SC1299 supports 12V lead-acid batteries, including standard flooded, AGM, and gel designs, making it versatile across many vehicle types. It’s suitable for motorcycles, ATVs, cars, trucks, SUVs, and many marine applications where a gentle maintenance charger is required.
