ADAC Tip: This is How Full Batteries Prevent Car Breakdowns

The cold season is approaching, and with it the risk of vehicle breakdowns due to dead starter batteries increases – according to the ADAC breakdown statistics, the most common cause (around 44 percent) for stranded vehicles; incidentally, also for electric cars. The mobility club therefore points out that vehicle owners can avoid battery failures through simple measures.

Regular Maintenance Especially Important

Regular maintenance of the starter battery is particularly important to prevent unpleasant surprises during the winter months. A well-charged battery not only ensures a trouble-free start but also prevents damage from deep discharge or even the freezing of the battery.

To preserve the battery, trips over very short distances, where the alternator has little time to sufficiently charge the battery, should be avoided if possible. Ideally, longer trips should be undertaken regularly. This allows the battery to fully regenerate. The battery should also be regularly checked to avoid leakage currents. It is also important to protect the contacts from corrosion.

Important to note

For vehicles that are not used for extended periods or frequent short trips, it is advisable to regularly charge the battery with a suitable charger. When purchasing a charger, consumers should pay attention to the following features:

• Compatibility: The charger must be suitable for the specific battery technology (for example, lead-acid, AGM or gel).
• Multi-stage charging system: A charger with multiple charging phases ensures a gentle and thorough charge. This extends the life of the battery and protects it from overloading.
• Protection mechanisms: A good charger should have overcharge protection, short circuit protection, and protection against incorrect polarity. These features ensure safety and prevent damage to the battery.
• Maintenance charging: Especially during longer vehicle idle times, such as often occur in the winter months, a maintenance charging function ensures that the battery remains at an optimal charge level without overcharging it.
