Frequently asked questions (FAQ).

Battery Capacity Meter

Accurately Measures Battery Capacity

Multi-colored LED scale monitors battery bank voltage and capacity in 10% increments. The LED's light one at a time to indicate percent of change.

Float, Equalize, & Low Voltage

The Battery Capacity Meter has separate LED's to indicate the Float Voltage, an Equalize Voltage and Low Voltage. These indicators are important for proper battery maintenance.

Advanced Circuitry

Advanced solid-state integrated circuits are used to accurately measure battery voltage. This package ensures that the BCM can be relied on for years, if not decades, of worry-free service.

Suitable For Marine Applications

Durable weather proof casing and solid-state circuitry make the BCM a valuable tool in marine or industrial applications.
