What is the best way to maintain the battery life of a Vauxhall Grandland?

I have noticed that the battery life of my Vauxhall Grandland is decreasing. What are some tips and tricks to maintain its longevity?

Regularly check and clean the battery contacts to ensure proper charging and avoid buildup of corrosion. Also, avoid leaving the radio or lights on for extended periods when the engine is off.

Consider investing in a battery maintainer or trickle charger to keep the battery charged when not in use.

Make sure to fully recharge your battery after it has been drained, as repeated partial recharges can decrease its lifespan.
