Fitting advice
Guides
These guides answer the questions that come up before a mobile battery visit or a jump start.
How much does mobile car battery replacement cost?
Mobile car battery replacement cost depends on type, size, location and registration. The figure is on the callback.
AGM versus EFB battery
AGM replaces AGM. EFB can be replaced or upgraded to AGM. A plain flooded battery is the wrong substitute.
What battery does my car need?
Match flooded, EFB or AGM, plus case size, Ah and cold cranking current, before a mobile fit.
Stop-start battery replacement explained
Stop-start cars need an EFB or AGM battery, fitted at the vehicle and registered when the model requires it.
Can you fit a car battery at home?
Yes. A car battery can be fitted at home, at work or in a car park in London, Birmingham and Manchester.
Battery registration: which cars need it?
Battery registration is common on Volkswagen Group and many BMW and Mini models. Other marques vary.
Mobile battery fitters: what to expect
What a mobile battery fitter does at the car in London, Birmingham and Manchester, after a quote callback.
Fitting a battery you have already bought
A correct customer-supplied battery can be fitted at the car. The type, size and terminals must match.
Battery under the seat or in the boot
Some car batteries sit under a seat or the boot floor. The mobile fit follows that location, at the vehicle.
CCA and Ah ratings explained
CCA is cold starting current. Ah is capacity. Both should match the battery the car was specified with.
How long does a car battery last?
Battery life depends on trips, heat and stop-start use. This page gives no year count. Replace it at the car when it is finished.
Wrong battery type on a stop-start car
A flooded battery in a stop-start car can disable stop-start. Fit EFB or AGM and register when required.
Disposing of an old car battery
On a supply-and-fit visit the old car battery is taken away. It does not go in household rubbish.
Battery hold-down and terminals
The hold-down stops the battery moving. Clean, tight terminals keep the cranking path sound.
AGM battery replacement cost factors
AGM replacement cost follows the AGM spec, where the battery sits, and whether the car needs registration.
EFB battery replacement at home
EFB battery replacement at home is a mobile fit on the drive or at another parked car in the three cities.
Fitting a battery on a driveway
Driveway battery fitting means the fitter works at the parked car, with the handbrake set and room to open the bonnet or boot.
Van and SUV battery fitting
Van and SUV batteries are often larger, or hidden under a seat or boot floor. We'll come to the car.
Hybrid 12V battery replacement
Hybrid 12V replacement covers the auxiliary battery only. The high-voltage traction pack is left alone.
What happens during a mobile battery fit
A mobile battery fit is a set sequence at the car: inspect, test, replace, secure, register if required, and check charging.
