What's the best way to preserve the battery life of my Audi e-Tron during long periods of inactivity?

I will be away for a month and won't be using my Audi e-Tron during that time. I'm worried about preserving the battery life. What can I do to ensure the battery remains in good condition during this long period of inactivity?

The best way to prevent battery drain during long periods of inactivity is to keep the battery charged to around 50-60%. This will help prevent the battery from fully draining and potentially damaging the cells.

If possible, it's always best to store your Audi e-Tron in a cool, dry place. Extreme temperatures can have a negative impact on the battery life. If a garage or covered parking spot is not available, try to find a shaded area to park.

Consider investing in a trickle charger or a battery maintainer. These devices can be connected to the battery during periods of inactivity to keep it charged and maintain its health. Just be sure to follow the instructions carefully to avoid overcharging.
