How much does mobile car battery replacement cost?
The price depends on the battery type, the case size, where it sits, and whether the car needs the new battery registering. We'll quote that car. We fit in London, Birmingham and Manchester.
The figure is for one car
Two replacements are not the same job. A flooded battery under a bonnet, with no registration, is a shorter visit than an AGM in a boot floor that has to be written into the car with a scan tool. Asking for a single public price ignores that difference.
Mobile Car Battery Fitting does not print a tariff. You type your mobile number on the quote form. We call you back with a figure for the vehicle and the place, in London, Birmingham or Manchester.
What the callback is pricing
Technology comes first. Flooded, EFB and AGM are different batteries. An AGM must not be downgraded, so that car is quoted as AGM. An EFB may stay EFB or move up to AGM. Case size, Ah and cold cranking current have to match the label.
Location is next. Engine bay, boot or under a seat changes the panels that come off. Registration is commonly required on Volkswagen Group and many BMW and Mini models and varies on other marques. When it is required, it is inside the quote, not a surprise after the clamp is tight.
What does not belong in the price conversation
A jump start is not a discounted replacement. Leads do not equal a new battery, and a cracked, leaking, swollen or frozen case is not jumped at all. The alternator is not a bulk charger, so a plan to drive the battery better is not a quote.
Access still matters. A clear drive is different from a boot against a car park pillar. Say which it is. If the car is in a live lane, call 999 before you ask what a fit would cost.
Questions before you send a quote
Why will you not give a price on this page?
Because the car sets the job. The callback gives the figure after you leave your mobile number.
Does registration change the quote?
Yes, when the model needs it. That is common on Volkswagen Group and many BMW and Mini cars.
Can I supply the battery to change the quote?
Yes, if it is the correct spec. Say so on the form. A wrong battery is not fitted.
A worked example
A 2017 Volkswagen Golf with stop-start, an AGM battery in the engine bay and registration on the visit is a different quote from a 2008 Ford Focus with a flooded battery and no registration. The difference is the battery, the registration step and the case. The figure is given on the callback, not from a menu.
