Schumacher SC1437: Professional Heavy-Duty Manual Charger

The Schumacher SC1437 is a high-performance manual battery charger designed for the professional shop environment or the serious home mechanic. Unlike automatic chargers, this manual unit gives the operator full control over the charging process, making it an essential tool for reviving deeply discharged batteries that "smart" chargers might ignore. It is built for 12V lead-acid batteries and can handle everything from motorcycles to heavy-duty trucks.

Key Technical Features:

• Powerful 150 Amp engine start for immediate vehicle ignition.
• 30 Amp quick-boost mode for rapid energy recovery in minutes.
• Heavy-duty transformer and rugged steel case for long-term durability.
• Easy-to-read analog meter for monitoring charging progress.

The SC1437 features an integrated 135-minute timer for precision charging and a "Hold" position for continuous operation. Because it is a manual charger, it requires monitoring to prevent overcharging, but it offers the raw power needed for fleet maintenance and emergency jump-starting. Its heavy-duty clamps and thick cables ensure maximum current transfer even in cold weather.
