We offer a Battery fitting service in store where they can retain the radio code using specialist equipment.

A fully charged battery will show 12.5 volts.
It is possible to charge a battery above 12.5 volts. Charging a battery above 14.4 volts will cause the battery to gas and electrolyte will be lost.

Calcium batteries use advanced chemistry for the internal construction giving a superior performance and benefit from a longer guarantee

Halfords car batteries comply to the new EN battery standard used by all motor manufacturers.
This new standard uses different test criteria. A comparable rating is approx. 44AH

Some modern batteries do not require external vent pipes. We advise you to visit your local store for further assistance.

For years the accepted bench charging rate of a battery was 10% of its capacity. We recommend using Halfords battery chargers which will not damage the battery.

The number is the month and year of production. If the battery is in a low state of the charge, the battery charger may not be sophisitcated enough to recharge the battery correctly - this is common with older / budget chargers being used on calcium batteries. Also, if the battery has been left in a low state of charge - ie below 12.4volts, sulphation damage may have started. This is a chemical reaction that takes place within the battery - the sulphate from the sulphuric acid attaches itself to the plates - if it is allowed to 'crystalise' it forms permanent and irresversible damage to the plates that prevents the battery absorbing the charge.

Please see our advice centre for detail.
