Electrocine [sales] corporation offers battery capacity tester. It is manufactured to discharge the battery at certain current to calculate current discharging capacity of the battery in amp/ hour. The advantages in this electronic solid state battery capacity discharge test set is that the discharge current can be continuously adjustedfrom 0 to 10 or to 20 or 0 to 30 or any other specific range and the discharge current remains constant or reduce even if the battery voltage reduces. Hence the discharge current is constant during its entire test period. The tester facilitates a voltage set limit to shut off the test when the preset level of battery is achieved. A clock is provided along with it to register total time for discharging a battery to urn permissible level of voltage. The system can also be given with constant charging current facility and a counter to count charge and discharge cycles of the battery.
