Popis: In France, the annual average purchases per person is 19 primary household batteries and 2 rechargeable batteries. Despite the obligation for each battery seller to have a collection point, only 50% of these domestic accumulators are recycled in France. Among the numerous reasons that users do not use home rechargeable NiMH batteries to their discharge limits, this article will mainly discuss the lack of easy-to-use and inexpensive function testing. An "open source" tester-loader with many possibilities is proposed. In particular, a test by the linear regression method making it possible to reduce the test duration of NiMH batteries from 6 hours to 1.5 hours to check the energy capacity of each accumulator is presented. Since 2019, lithium-ion batteries in domestic cases have been marketed with few characteristics provided by manufacturers on their obsolescence and their capacities. In this article we present performance tests carried out to verify the energy capacity as a function of the output current.
