Proper automotive battery maintenance helps extend its lifespan and reduces the risk of starting problems.Nowadays, most automotive batteries come in two types: Maintenance-Free (MF) and Conventional (wet cell). Each type requires slightly different care, but the key practices are as follows:
1. Check Electrolyte Level: For conventional (wet) batteries, check every 2–4 weeks or every 1,000 km. For maintenance-free batteries, check every 3–6 months or every 10,000 km. If the level is low, refill with distilled water. Do not exceed the maximum level, as this helps prolong battery life.
2. Clean Battery Terminals: If there is corrosion buildup, clean it using a brush or a cloth with warm water, then wipe dry. This helps prevent further corrosion and ensures good electrical conductivity, extending battery life.
3. Check Tightness of Terminals and Battery Hold-Down: Ensure that the terminals and mounting brackets are securely fastened to minimize vibration, which can shorten battery lifespan.
4. Inspect Charging System (Alternator): If the battery warning light appears on the dashboard, the engine is difficult to start, or the lights are dim, the alternator may be malfunctioning (overcharging or undercharging). It should be checked immediately to prevent battery damage.
5. Start the Vehicle Regularly: Leaving the vehicle unused for long periods can lead to self-discharge. Start the engine and let it run for about 15–20 minutes, 1–2 times per week, to allow the alternator to recharge the battery.6. Avoid Using Electrical Devices Without Starting the Engine: Avoid using headlights, audio systems, or other electrical devices for extended periods while the engine is off, as this may drain the battery and prevent the vehicle from starting.
