12V Smart Charger for Lead-Acid Batteries

This BatteryJack inc. charger maintains 6V and 12V lead-acid batteries from 2Ah to 90Ah. It supports SLA, AGM, GEL, and VRLA types with an LCD display and automatic operation. The unit delivers up to 3.8A charging current at 14.4V or 14.7V maximum voltage. Full protection covers reverse connection, over-charge, short-circuit, over-temperature, and high-low voltage faults.

Suits Motorcycle, Car and Seasonal Vehicle Owners

Riders and drivers wanting a maintainer for motorcycles, cars, or snowmobiles will find the selectable terminal settings and automatic modes convenient. Buyers needing to charge lithium-ion or LiFePO4 chemistries should look elsewhere, as this unit is designed solely for lead-acid types. Those requiring input voltages other than 120V 60Hz cannot use this charger without external conversion.

Detachable Leads and LCD Change Daily Use

Interchangeable alligator clips and ring terminals let you switch between quick garage top-ups and permanent vehicle-mounted connections. The LCD indicator shows real-time status so you can confirm charging progress without guesswork. Automatic float and trickle modes mean the charger can stay connected long-term without manual intervention.
