Frequently Asked Questions

What types of batteries is the BCD-12120B suited for?
This charger is designed for 12V lead-acid batteries, including AGM, flooded, and gel batteries ranging from 200Ah to 800Ah. It’s ideal for heavy-duty vehicles, backup systems, marine fleets, and large battery storage banks.

Can it maintain voltage during ECU programming?
Yes. With a stable 120A output, the BCD-12120B ensures constant voltage during diagnostic sessions and ECU flashing, keeping tools and vehicle systems online without voltage dips or restarts.

Is it safe for continuous use in a workshop?
Absolutely. The unit is fuse protected, with built-in over-current, over-voltage, and short circuit protection. It’s designed for continuous-duty cycles in high-traffic service areas, with reliable cooling and surge protection included.

Is the charger portable?
Yes. Weighing just 10.2 kg, and fitted with a wide carry handle and integrated clamp holders, it’s easy to move around the workshop. The 3-metre cables offer extended reach across bays and larger vehicles.

What makes this charger better than lighter units?
Unlike standard chargers, the BCD-12120B delivers sustained 120A output, making it capable of charging or supporting very large battery systems efficiently and without heat overload. It’s built for commercial reliability, not just occasional use.
