Some may disagree...
But what I do during the winter months in WI. is:
First check the water level in all of the batteries, then fully charge the cart,
After it's charged, disconnect the charger for 5 minutes,
Then... plug the charger back in again, until it shuts off again
when it's done charging the second time, remove the charger, and put the run/tow switch in "TOW"
and disconnect the
2 main positive and negative cables from the whole pack, and your stored!
hope this helps!
