To avoid getting stranded with a dead battery, accurate battery bank monitoring is essential. Voltmeter Method—Voltage can be used to measure of the SoC of your battery. The difference from a fully charged battery to a fully discharged battery is only 1.0V in a 12V system, so the meter must have good resolution and accuracy. This method is generally sufficient to monitor batteries which experience intermittent use, such as starter or thruster batteries. However, a battery must not have been charged or discharged for over 12 hours for this measurement to be trustworthy. This makes the Voltmeter Method unsuitable for monitoring house batteries which charge and discharge often. Amp-Hour Method—A convenient and accurate way to measure SoC is with an Amp-Hour Monitor. This is a complex calculation of the energy available, energy consumed, and energy returned to the battery during charging. SoC can be expressed as amp-hours used, amp-hours remaining until the battery is empty, or time remaining until the battery is empty. The advantage of this method is that it works well for batteries in a constant state of charge and discharge.
