Abstract
A method of testing applicable to the routine testing of batteries for automotive vehicles and like batteries is described. The method comprises: providing a battery to be tested; providing a test electrical load for connection to the battery; providing a control circuit to connect the load to the battery for an interval of less than one second; and providing analysis means to analyze the battery's reaction to said load. The invention is characterized by causing the load to cause the battery to deliver a macro-current which is comparable to currents arising in use of the battery; causing said control circuit to connect the load to the battery for a transient time interval lying in the range of up to 100 milliseconds; and providing the control circuit as part of handset apparatus adapted to be operated and connected to the battery in the manner of a testing handset, and the transient macro-current generating an amount of heat in relation to the handset which can be accommodated by apparatus of the handset kind.
