How to charge Audi Car Battery

If your Audi battery died because you forgot the lights or the radio on, it doesn't mean that you need to replace the battery. To fix this problem, charge the battery the using a trickle charger. A trickle charger provides a small current which brings the battery back to a fully charged state. 

Of course, you can always jump start your Audi with a jump box or another car, but doing so can have an impact on the life of the battery. It can trigger low voltage fault codes in various modules and even send your Audi in limp mode in some cases. If time is not a restraint, charge Audi battery following the directions below.

What you will need

trickle charger outputs between 2 and 12 amps. Smart chargers prevent the battery from overcharging which could be damaging.

Allow the battery to charge for a few hours. Monitor the vehicle for the first couple of hours and not leave the vehicle unattended. If the battery overheats during charging disconnect the charger. We recommend using a Smart Charger to prevent the battery from overheating. If your Audi battery is completely dead it can take more than 5 hours to charge the battery.
