Advanced functions and features can be found in many modern battery monitors, including:
- Time Remaining—Provides a rough estimate of how long the batteries could sustain a given load based on time-averaged increments (i.e., 4, 16, or 32 min.).
- Cumulative Amp-Hours—A cumulative count of Ah in or out of the batteries. Useful in estimating battery age or total charging-source production.
- Peukert Exponent—Factors in the discharge rate’s effect on battery capacity.
- Charge Efficiency Factor—Accounts for charging efficiency losses.
- Multiple DC Inputs—To monitor more than one battery bank, charging source, or load simultaneously.
- Data Logging—Uses a communication port to export data to a computer, a data logging device, or the Internet.
- Remote Display—Allows a separate display to be conveniently mounted away from the monitor.
- Usage Readings in kWh—Make it easier to directly relate the amount of remaining battery capacity to the load ratings of household appliances.
- Relay Control—Activates a relay at a preset voltage point to start a generator, manage a load, etc.
- Alarms—Signal low battery, loss of meter power, etc.
- Battery Temperature—A sensor can be placed on the battery and wired into the monitor to report battery temperature.
