How Long Does a Focus Battery Last?

[StHope]

The typical lifespan of a Focus battery ranges from two to five years, but with good usage habits, it can last over five years. The original battery features an inspection window where the color indicates the current battery status. The factory-installed Focus battery is a maintenance-free unit manufactured by Varta. To maintain the battery, avoid prolonged use of electrical devices like air conditioning, lights, or entertainment systems (e.g., radio) while the engine is off. If the vehicle remains parked for over a week, start the engine for at least half an hour to allow the alternator to recharge the battery. In winter, minimize repeated starter motor engagement to prevent excessive battery discharge and damage. The Focus is a compact sedan produced by Changan Ford, with dimensions of 4378mm (length) × 1810mm (width) × 1468mm (height) and a wheelbase of 2705mm.
