Waiting around in the cold when you should have been dropping of kids or in an important meeting is no fun either. Having a flat battery usually means having to call for roadside assistance, and roadside assistance isn’t cheap. Significant charging requires driving much longer distances.īy using an onboard charger like MultiCharger 1204, you ensure that your battery is always fully charged and ready to start your car. At -10☌, you have to drive an average of 7 kilometers before the battery even starts charging. Unlike what many car owners believe, a typical driving pattern is not enough to keep the battery sufficiently charged over time, especially in winter. MultiCharger 1205 Flex keeps your battery fully charged.

Using fuel-operated heaters only exacerbate the problem, as they draw a lot of power from the battery when starting. Along with the power needed for an increasing number of electronic systems in modern cars, this leads to the battery becoming drained. Frequent use of comfort features like seat and window heaters is another factor that draws a lot of power from the battery. Most of us are almost as unhappy about the cold as batteries are. Without the use of a battery charger, the battery routinely only charges to 60-80% of its capacity during winter. Cold weather also increases the resistance in the battery, reducing how efficiently the car’s alternator can recharge it. At -18☌, even a new battery can only perform at 40% of its original capacity. Sub-zero temperatures weaken the battery more than most people realize. Getting to your car on a cold morning and discovering that it won’t start because the battery is flat is as infuriating as it is common, especially in winter. Avoid flat batteries and get a car that always starts.
