Smart Charger for Lead-Acid Batteries

The BatteryJack Banshee is a fully automatic 0.75 amp charger and maintainer designed for 6 V and 12 V lead-acid batteries. It automatically senses the battery voltage and selects the correct charging profile. An integrated voltage tester and LCD with bar graph show the state of charge. Digital prompts guide the user through each step of the process.

Replacing Manual or Single-Voltage Chargers

This unit replaces separate 6 V and 12 V chargers as well as basic trickle chargers that lack maintenance logic. The jump is worth it when you store vehicles, boats, lawn mowers or tractors for weeks and need the battery kept at full capacity without overcharging. It is not for buyers who need rapid charging of large automotive batteries or simultaneous charging of multiple banks.

Sustained Maintenance Behaviour

During prolonged connection the charger holds the battery at a safe float voltage of 7.2 V or 13.9 V depending on the detected system. Protection circuits guard against short circuit, reverse polarity, overcharge and overheat continuously. The hook attachment keeps the unit outside the work area while it maintains the battery indefinitely through seasonal storage.
