Benchtop Charger for 6 V and 12 V Batteries
This Westward benchtop unit charges AGM, deep-cycle and lead-acid batteries at 6 V or 12 V. It delivers a 100 A boost at 12 V for jump starting, a 15 A charge rate at both voltages and a 2 A maintenance mode. Automatic on/off control handles the cycle without user intervention.
Suits Workshops Needing Boost and Maintain
Technicians who need a single bench device for boosting, charging and long-term maintenance of 6 V and 12 V lead-based batteries will find the required modes here. Buyers who require a portable jump pack, a charger for lithium chemistries or a higher continuous charge current should look at other equipment.
100 A Boost Current at 12 V
The 100 A boost rating at 12 V is the decisive figure for starting vehicles with discharged batteries. If the application only needs charging or maintaining, the lower 15 A and 2 A rates apply, but the boost capability is what separates this unit from basic maintainers.

Questions about this item
How do I connect the 6 ft cables to a 12 V battery for the 100 A boost without reversing polarity?
Attach the red clamp to the positive terminal and the black clamp to the negative terminal on the 12 V battery, then plug the unit into a 120 V AC outlet and select the boost function; the automatic charge type will manage the 100 A surge.
When should I expect the internal cooling fan or the 2.2 A input circuit to require service after repeated 15 A charging cycles?
The charger has no user-serviceable fan or fuse listed; keep the 6 ft cables and vents clean, and if the 15 A charge rate drops or the auto on/off function fails, have a qualified technician inspect the 120 V input stage.
At what point does the 100 A boost mode time out or overheat during a prolonged engine start attempt?
The automatic boost function monitors battery voltage and will reduce current or shut off if the 12 V battery reaches full charge or if internal temperature exceeds safe limits, protecting both the charger and the vehicle electrical system.
