6V and 12V lead-acid charger

This smart charger maintains 6V and 12V lead-acid batteries in motorcycles, cars, boats and RVs. It delivers a constant current of 3.0 A and automatically shifts through three charging stages. The unit operates from 100 to 240 V AC at 50 to 60 Hz and includes short-circuit, polarity and over-voltage protections.

For seasonal vehicles and standby batteries

Suits owners who need to keep starter batteries topped up during storage or infrequent use. The automatic float stage holds voltage between 6.7 and 6.9 V for 6V packs or 13.5 and 13.8 V for 12V packs without overcharging. Not for lithium chemistries or for rapid recovery of deeply discharged high-capacity banks.

LED status and safety cut-outs

A red LED shows charging in progress and a green LED confirms the battery is fully charged. The charger shuts off automatically once the float voltage is reached, preventing damage from prolonged connection. No extra cables or software are bundled beyond the mains lead and output clips.
