simple method to measure battery capacity
Without sophisticated electronics, simple method to measure battery capacity : 1 relay, 1 zener, 2 diodes, a resistive load, 1 timed switch, time counting accessory.

good morning ,
I designed this to measure the status of some second hand batteries , but i wouln't use hard electronics circuits ( processor) nor integrated circuits ( op amp , comparators ...) !
1 relay with parallèl diode ,
1 zener ,
1 diode ( protection against load current ),
1 load ( could be a car lamp ...)
1 temporary switch ,
1 time counting accessory .
that's all , best regards , Alain
