46. ntroduction Why should I use the Magnum Battery Monitor To ensure your batteries perform satisfactorily and have a long life they need to be properly maintained and charged There are several devices that help to determine if the batteries are being fully charged e DC Voltmeter An accurate DC voltmeter can be used to measure the Open Circuit Voltage OCV across the battery terminals and compare the readings with the OCV values from the battery manufacturer A DC voltmeter is the least costly but is also the least accurate and requires the batteries to be at rest This rest requirement means the voltage measurement should only be done when there is no current moving through the battery for a pe riod of time most experts say a minimum of 1 hour Using a DC voltmeter when the batteries are at rest is generally impractical because the batteries are usually always powering loads or being charged e Hydrometer A good hydrometer can be used to measure the concentra tion of battery electrolyte in each individual cell and compare these readings with the specific gravity values from the battery manufacturer A hydrometer is very accurate but can be time consuming and becomes unpleasant when working with sulfuric acid A hydrometer won t work with sealed batteries e Amp hour Meter An amp hour meter is an electronic measuring device that uses a precision shunt to calculate the amp hours going into charging and coming out of dischargi
