Maintaining Your Porsche’s High-Voltage Battery: Best Practices

Generally, as long as you charge the battery between 20% and 80%, stay away from extreme heat, and use OEM charging equipment, you’ll avoid the biggest consequences of poor battery maintenance. Keep reading to learn specific tips for maintaining the battery system on your electrified Porsche.  

Porsche High-Voltage Battery Maintenance Tips

Charging Habits

Try not to let your battery fully drain or discharge. Ideally, you don’t want your Porsche battery charge level to fall below 20%, but you also don’t want it to exceed 80%. If you can, try not to charge your Porsche every night.

Your driving style and driving conditions can negatively impact your Porsche battery’s longevity. Extreme heat, whether it’s from long periods sitting in traffic or heavy continuous use, can cause excessive wear on the battery as well as short bursts of heavy power usage which can degrade the battery.

Preferred Chargers

Level 1 and Level 2 OEM chargers are preferred over the DC fast chargers. While their quick charging ability is certainly convenient, DC fast chargers can reduce your Porsche battery’s lifespan if used too frequently. Use the My Porsche App to monitor your charging status when using the DC fast chargers, and try to stop charging before the battery level goes above 80%.

Best Practices when Driving

When you take your Porsche out, try to park in a shady spot or inside a covered garage. Leaving your Porsche in direct sun can lead to the battery overheating which can impact its reliability. Driving your Porsche outside of the ideal temperature range usually won’t cause irreversible damage, but if you’re driving it far outside its ideal range of 32 to 68 degrees Fahrenheit, expect additional wear and tear on the battery system.

Maintenance and Care

If you’ll be leaving town or know you won’t be driving your Porsche for a while, plan to regularly check its battery level to keep it within the ideal charge range. You can periodically start it and also connect a trickle charger to prevent the battery from draining completely.

You should also consider deactivating Instant Charging if it’s a feature of your Porsche. Instant Charging can lead to overcharging and increase the chances of damage to the battery. To ensure you haven’t missed any maintenance tasks and to check your Porsche battery health, you can visit our Porsche Center and let the service department inspect your battery and perform any suggested maintenance.

Do your best to adhere to the maintenance tips listed above and your Porsche’s battery system will remain safe and reliable until you’re ready to upgrade to a new Porsche EV or hybrid in the future.
