Smart 12 V charger with LCD

The BatteryJack 12 V maintainer is a fully automatic smart charger designed for lead-acid batteries in motorcycles, cars and snowmobiles. It detects the connected battery type and manages the charge cycle without user intervention. The built-in LCD shows real-time status so owners can confirm progress at a glance.

2–90 Ah capacity range with 3.8 A peak

The unit charges 6 V and 12 V SLA, AGM, GEL and VRLA batteries from 2 Ah up to 90 Ah. Maximum charging current reaches 3.8 A with a tolerance of ±10 %, while peak voltage is limited to 14.4 V or 14.7 V depending on chemistry. Batteries larger than 90 Ah fall outside the supported range and will not charge correctly.

Swappable leads and full protection suite

Detachable alligator clips and ring terminals are included so the same charger fits permanent or temporary connections. Reverse-polarity, over-charge, short-circuit, over-temperature and high-low voltage protections are all active. The charger operates from a 120 V 60 Hz mains supply and requires no additional software.
