Tip
Geoff Noll says:
If you remove battery acid from each cell with your hydrometer, & keep in a
clean bucket for use later, dissolve 220grams of epsom salt into 550ml of rain
water, snow, or distilled water at 150 degrees, stir until the ES is all mixed
with the water, then add 83ml of this ES water to each cell, the top up the
cells to normal level using the saved battery acid, then charge the battery, or
install battery in your vehicle & jump start, then go for a drive, the vibration
will mix the ES water throughout the battery stripping off all sulphate allowing
a full charge to be achieved.!! ... I've done this 6 times, my battery was
bought in 1997.
