For some critical application like Aircraft auxiliary supply or on board a large ship or submarine, It becomes necessary to check the performance of a battery bank on a regular basis just to see how well it will cater to a fixed load for the entire duration of its journey including emergency operations. This is usually done by measuring its Ampere Hour Capacity. The Capacity Tester is one such equipment or device useful for measuring the capacity of Lead-Acid or Ni-Cd battery bank of 6V, 12V & 24V up to 500Ah capacity. It also has the facility of checking the capacity of a single 2V cell 200Ah capacity.
