Fitting and everyday care
A caravan that spends the winter parked on the drive often comes back in spring with a flat battery. Keep a battery monitor reset after fitting new batteries. A motor mover that struggles may be a sign of a weak battery.
What lead-acid means for you
Wet lead batteries started engines long before the first motorway was built. Simple design makes flooded batteries easy to recycle. Keep flooded batteries upright.
