Check Battery Voltage and Chemistry First

Verify that your battery is either a 12V or 24V model and that its chemistry appears in the supported list. Choose the current setting of 30%, 60% or 100% of the maximum output to match the battery size and condition before connecting.

Protection Maintains Output During Long Charging

Built-in temperature, low-voltage, overvoltage, short-circuit, overcurrent and electrostatic-spark protections keep the charger running safely from -10°C to 40°C. Pulse repair and trickle modes sustain the battery without stress during extended maintainer use.

Questions about this item

Does the charger come with cables or do I need to buy them separately?

The product information lists the charger unit with selectable current modes and multiple protection features.

Should I use the 12V 25A or 24V 13A setting for my battery?

Use 12V 25A for 12V batteries such as cars, motorcycles or lawn mowers. Use 24V 13A for 24V systems found on some boats, forklifts or golf carts. Match the voltage to your battery.

What does the 25A peak current mean when I am actually charging?

The 25A maximum is available at 12V on the high 100% setting. You can also choose 30% or 60% of that current. The charger then holds a lower trickle current once the battery reaches full charge.
