My car battery is oversized for the car. The battery is a bit old but usually works fine. The battery is flat (I left the lights on).
My fancy new modern charger senses a poor battery and only puts in very little charge.
I used to use a really old charger to charge this battery successfully. I opened up the old charger and saw it was only a transformer and a big rectifier. That's it. No soothing.
Is this ok for a car battery or is it way too crude?
