Battery Capacity Tester
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 Battery 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.
- Rugged construction and portable.
- Long service life since the unit is fully solid-stat, micro-controller based.
- Provision of 6V, 12V and 24V battery capacity test and protection against wrong Battery Switch Selection.
- User friendly, all controls and settings are provided on the front panel. The under voltage setting at which the battery discharging is terminated is done through Key Pad.
- Temper proof settings such that the unit stops all operation reset if the settings are changed during operation.
- Provision of a direct Ah reading.
- Audio alarm for “Battery Low” and “Test Completed”.
- Retention of capacity reading even after power shut-down.
