Smart Charger for Lead-Acid Batteries

The Banshee Smart Charger Maintainer automatically senses 6V or 12V lead-acid batteries and delivers a 750mA charge current. It suits owners of motorcycles, lawn tractors or seasonal vehicles who need to keep stored batteries topped up without manual intervention.

Automatic Voltage Detection

The unit detects whether a connected battery is 6V or 12V and selects the appropriate charging voltage of 7.2V or 13.9V. This single function decides if the charger matches the battery in your application.

Protected Maintenance Charging

Under sustained connection the charger switches to maintenance mode to prevent overcharging while guarding against short circuit, reverse polarity and over-temperature. The LCD shows measured voltage and a charge-level bar graph throughout the cycle.

Questions about this item

What does the 750 mA charge current mean for a battery sitting in my garage?

It delivers a gentle 0.75 amp trickle charge that keeps a lead-acid battery topped up during storage without overcharging.

What does the dual 105-125 V and 220-240 V input actually let me do?

You can plug it into standard household outlets at either 60 Hz or 50 Hz without a separate adapter.

How does the hook attachment help when I mount the unit?

The built-in hook lets you hang the charger outside the work area so cables stay clear and the unit stays ventilated.
