Rust Collector Posted December 15, 2022 Share Posted December 15, 2022 13 hours ago, wuvvum said: Cheap IMA Civic which isn't charging its main battery. I assume it's not just a standard alternator on these? You can build a mains charger using LED drivers. As long as none of the cells are physically damaged then you can limp some life out of them through mains charging. Using a bulb or big resistor you can discharge the pack before charging, doing this over a few cycles apparently helps balance the pack if there’s weak cells. My 22 year old pack in the Insight is being kept alive this way, as when left unused too long it sinks into a state of charge where the battery controller refuses to charge the pack. Obviously it’s just delaying the inevitable, but it’s still perfectly workable. Link to comment Share on other sites More sharing options...
