I'd heard this before but I'd never seen it work. Yesterday at 30 °F my loader tractor (800 series Ford) started and died, started and died and then would barely turned over. Pulled battery and put on charger. Battery showed 12.7 volts after charging at six amps and passed the load test right off the charger. This seemed encouraging but the charger had been still delivering 3.5 amps after several hours before the load test. I put it back on at two amps thinking I'd top it off and then load test it after sitting overnight. After a couple of hours the charger was still delivering 2 amps. So I shook the battery a few times. Tilted it back and forth picked it up shook it, etc. I then hooked the charger back up at two amps and could watch the amp needle move to zero in a matter of minutes. Seems that sediment must have been shorting some cells??
I'm going to go load test it in a few minutes after sitting for 15 hours, what do you think I'll find? It's a five-year-old battery - 575 CCA. Wouldn't mind getting a few more months out of it, but will replace it if the test fails as I'd like it to start on cold days. I'd heard of the shaking cure, but had never seen it in action.
