Why does my Lexus battery keep dying?
There can be several reasons why a Lexus battery keeps dying. Here are some possible causes:
1. Parasitic power draw: If something is drawing current from the battery even when the car is turned off, it can drain the battery over time. This could be due to a malfunctioning component or an interior light that doesn’t turn off.
2. Charging system issues: Problems with the alternator, battery, or battery cables can cause the battery to drain. If the alternator is not generating enough energy to recharge the battery, it can lead to a dead battery .
3. Faulty battery: A battery with dead cells or leaks can cause it to die unexpectedly.
4. Short driving distances: If you frequently drive short distances, the battery may not have enough time to fully recharge, leading to a drained battery.
It’s important to note that these are general possibilities, and the specific cause of the battery drain in your Lexus may require further diagnosis by a mechanic.
