Battery Replacement | Ridgeway Jaguar Oxford

What we do and why?

Why does my battery need replacing?

When a battery is fully charged it supplies approx 12.6 volts. If the charge falls to 12.0 volts, the power it supplies drops from around 100% to approx 25%. A battery's efficiency is also temperature dependant and when cold, conductivity is reduced. If your battery is not holding its charge and we have a cold snap, it may cause your Jaguar not to start.

How often does it need to be checked?

The battery is so important that it should be checked at every service.

What happens if i don't replace it?

Sludge builds up in the bottom of the case and can short the cells out. Deep discharges, heat, vibration, over-charging, under charging or non-use, accelerate ageing. Ultimately if not replaced, the battery will fail, which means eventually your car won't start.

What do we do?

We check the battery's ability to hold it's charge. We may need to replace the battery if it's not holding a charge or look into the reasons why it's not charging when you drive.
