Amp Hour Meters

With the use of an amp-hour meter, you can tell the condition of your batteries at a glance.   An amp-hour meter is the best indicator of your system’s condition.   As you use power, the meter counts how many amp-hours are used.  As the battery is charged, the meter goes backwards, toward zero.  When the battery is full, the meter reads zero.  This type of meter is a must for nickel-cadmium and nickel-iron batteries, where it is hard to tell state of charge from voltage, or specific gravity.  The main destroyer of lead-acid batteries is sulfation caused by undercharging.  These sophisticated meters help you keep track of your battery’s state of charge so you can keep’em charged.   Get maximum life out of your batteries and save money and system down time.
Note: Amp hour meters lose accuracy if batteries are always run in a very discharged state.
