Winter Charging

Winter smart charging

Be winter smart. Charge your battery. Keep moving.

Your battery has to work so much harder to get your car started in colder weather. Your battery’s performance can also reduce by 35% when temperatures hit freezing and fall by as much as 50% if temperatures fall below zero.

So not only is your battery working less efficiently when the thermometer starts to drop, you’re also running the risk of vehicle breakdown, which can be expensive, not to mention extremely inconvenient.

So, when its cold outside, it’s absolutely essential to keep your battery fully charged and maintained with a reliable, efficient charger. And you’ll be reassured to know that you can rely on CTEK’s easy to use battery chargers to keep you out on the road, whatever the weather.

Peace of mind for cold weather starting

Charge your battery, extend its life

Avoid winter breakdowns
