Manitoba, Canada | The batteries won't freeze unless they are discharged. I would suspect you have a slow drain on the battery that discharges them over time. Does the semi sit for a couple of months at other times of the year and are the batteries dead then? If near a power source it is a good idea to hook up a battery maintainer to keep the batteries charged up. I would try to find the power drain to correct the problem. If the drain is not fixed and the semi is not near a power source and will sit for an extended period of time I would disconnect the batteries. | |
