Smart charger for 6V and 12V lead-acid batteries

The BatteryJack inc. smart charger automatically manages 6V and 12V lead-acid batteries from 2 to 90Ah including SLA, AGM, GEL and VRLA types. It suits motorcycles, cars and snowmobiles where a maintainer or full charge is needed. The LCD display shows status while the unit handles the process.

Sustained charging with full protection

The charger delivers up to 3.8A maximum current with voltage peaks of 14.4V or 14.7V depending on the selected mode. Built-in safeguards stop output on reverse connection, over-charge, short-circuit, over-temperature and high or low voltage conditions. This allows unattended operation without risk of damage.

Interchangeable leads for simple setup

Detachable alligator clips and ring terminals swap quickly so the same unit fits permanent or temporary connections. Select the terminal type then choose the vehicle profile and the charger runs automatically. Users must ensure the battery chemistry matches the supported lead-acid types.

Questions about this item

Does the 3.8 A charger run quietly and stay cool during long charging sessions?

The unit has no fan mentioned, so it operates silently; over-temperature protection will shut it down if internal heat exceeds safe limits.

What cables or connectors must I already have to use the 6 V / 12 V charger?

Detachable alligator clips and ring terminals are included, so no extra leads are required.

Will the automatic charger safely maintain the older 12 V AGM battery in my classic car?

Yes — it supports 2–90 Ah AGM, GEL, VRLA and wet lead-acid types with 14.4 V or 14.7 V maximum charge voltage and full protection circuits.
