TK1

Checked both batteries and they are full. I'm going to call the manufacture tomorrow and see what they say. It happened one time before but stopped so maybe the unit is going bad.

Thanks!

HI, I have the 3 bank model that is 1 yr old. I'm still new to bass boats. When I plug in in to charge I hear a buzzing sound from the one or both of the tm batt's and it sounds like bubbling or boiling coming from the batteries. The charger seems to be charging fine according to the lights on it. Could it be that the water in the batteries is low? They batteries are ever starts and 1 yr old. Thanks!
