We put a car in storage over the winter with one of those little 1A trickle chargers on the battery to keep it topped up.
It didn't work. The battery went dead, and I'm trying to figure out if it was operator error or something wrong with the charger.
It's possible I chose a bad ground point when I connected it, but when I metered the output of the charger expecting to see 12VDC, instead I saw what looked like pulses. Is that normal?
I reconnected the trickle charger to the battery and the red "charging" light came on. 24 hours later, the battery reads 2.7 VDC. If there's nothing wrong with the charger, then the battery is toast, but I'm not sure how to determine if the charger is OK.
