Overview of possible causes

A breakdown due to a depleted battery or a problem in the vehicle energy system is not necessarily the result of a defective battery. However, in some cases the battery can be damaged - no matter what the cause. The various causes can be placed in two main categories:

• Vehicle faults:
  • Vehicle does not assume sleep mode.
  • The vehicle keeps being woken up.
  • Excessive closed-circuit current.
  • Faulty alternator.
  • Faulty battery.
• Unfavorable customer behavior:
  • Side lights, parking light or hazard warning flashers were switched on for too long.
  • Terminal R or Terminal 15 switched on for too long
  • Long immobilization period.
  • Unfavorable driving profile.
