Be Ready. Be Charged. Be Winter Smart.

As winter sets in and temperatures drop, battery performance can reduce by as much as 50%. In colder weather you need much more power to get the vehicle started and an increase in short journeys puts the battery under a huge amount of strain. As a result, battery failure is the single biggest cause of breakdowns during the colder winter months. 

The alternator may only get the battery up to 60% of its capacity. To get the most out of your battery, so that it can keep all the vehicle’s electric systems working and always start when you need it to, charging the battery with a smart battery charger is essential – especially in winter. 

Take control of your vehicle battery and make sure you don’t get stranded out in the cold and dark with a flat battery this winter. Be charged and power through the cold!
