Method of testing a lead battery for the purpose of charging it under optimal conditions
First Claim
1. A method of testing a lead battery for the purpose of charging it under optimal conditions, wherein it consists in testing the lead battery for the purpose of obtaining information relating to its condition by applying a test current thereto and by increasing the voltage at the battery terminals, and wherein the method comprises a step of controlling the current by generating a variable-frequency function intended to produce a test cycle comprising the production of a current which increases up to a reference value chosen according to the capacity of the battery, which is held for a specific time defined by the capacity of the battery and which decreases such that there is significant excitation of the battery until a voltage close to its degassing voltage or greater than this voltage is obtained.
