Battery pad that inhibits corrosion on the tray

never used a battery mat...

a good 3 stage charger will eliminate electrolyte boiling and spillage. and give better battery life and performance.

I'm a big fan of por15.

I just clean my batteries and tray once a year. lots of baking soda and water, and I pull all the batteries out and clean under them as well.

If and when my battery slideout starts looking less than new, it will get the por15 treatment.
