Hi

Can anyone tell me what the normal charge voltage is for a V40 2.0T, it has heated seats etc so I don't know if that makes a difference.
At the moment it's about 13.4v and the battery drains over time.

Thanks

Sim

 

You are pretty close but what is the amperage you are putting out?
You need to check for a parasetic draw on your car.To make sure something is not staying on while the car is off.
