Hi people. Recently the battery of my Beetle is gone down. My friend told me to maintain the battery properly in cold weather. But Why one does needs a good battery in cold weather?

Basically in cold weather, the cranking load on the battery is much more compared to the summers. Because the weather is cols, the oil in the engine gets thicker and thus the cranking time goes high. If in that case, the battery of your car is low or let’s say the voltage is less than 12.45v, your battery needs urgent attention. If you ignore your battery then it will surely ditch you on the middle of the road.

Oh, I see! So it means the voltage should be minimum 12.45v in winters.

Exactly. If it is less, than you can recharge it using the portable car battery charger or by running your car every day for like 20 min. at40mph. Even that helps in maintaining your car battery.
