Compact 4-in-1 charger for lead-acid batteries

The BFKK unit combines a battery charger, maintainer, trickle charger and desulfator in one portable device. It works with 6-volt and 12-volt lead-acid batteries including flooded, gel, AGM, SLA, VRLA and maintenance-free types. Suitable for cars, motorcycles, boats, lawn mowers, golf carts, ATVs and UTVs. Not for lithium-ion or other non-lead-acid chemistries.

1.75-amp output with 7-stage repair program

The charger delivers a 1.75-amp current through a 7-stage cycle: desulfurization, trickle charging, constant current, constant voltage, current detection, compensation charging and floating charge. An LCD screen shows charging status, percentage, voltage and current. Built-in repair technology helps restore performance to old or idle batteries.

Automatic modes with 12.5-volt maintenance

STD mode cuts off power when the battery is full, while trickle mode maintains voltage at 12.5 volts. The charger locks its current mode during power outages and restarts automatically in the same mode when power returns. Extra-long 6.6-foot SAE cord with detachable alligator and ring terminals included. Not for buyers needing higher amperage for rapid charging of large banks.

Questions about this item

What does the 1.75-amp rating mean when the charger is connected to a battery?

It supplies up to 1.75 amps during the constant-current stage, then tapers off as the battery reaches full charge so the unit can maintain the battery without overcharging.

How does the SAE connector limit what I can plug in?

The 6.6 ft SAE cord accepts only the included alligator clips or ring terminals, so you must use those leads to reach the battery posts or a permanent SAE pigtail.

What clearance do the detachable alligator and ring connectors need to fit on a battery terminal?

The alligator clips open wide enough for standard top-post terminals, while the ring terminals bolt onto threaded posts or stud mounts with typical automotive spacing.
