A flat or dying battery is the most common reason a car won't start, and it almost always happens where the car is parked. That is exactly the job a mobile mechanic is built for. We come to your home or work, test whether it really is the battery, and fit a new one on the spot. That saves you jump-starting a flat car and driving it across town hoping it doesn't cut out on the way.

We replace batteries on all makes and models, including stop-start cars that need an AGM or EFB battery coded to the vehicle. Every battery is tested before we fit it and the charging system is checked so you're not left with the same problem a week later. Based in Soham, we cover Ely, Newmarket, Cambridge and the villages in between, and we can usually get to you the same day.

We come to you, same day where we can

A flat battery is the ideal mobile job. We fit the new one where the car sits, so you never have to risk a jump-start and a drive with a car that might cut out.

The right battery, tested before it goes in

We match the correct size, type and cold-cranking rating for your car, and test every battery before fitting so you get a good one, not just a new one.

Stop-start (AGM/EFB) coding included

Newer stop-start cars need the battery registered to the vehicle or the electrics play up. We do that coding as part of the job. Some places charge extra for it or skip it.

We check it's the battery, not the alternator

We test the charging system as well, so if the alternator is what's flattening the battery we spot it and tell you, rather than selling you a battery that won't fix it.

Battery or alternator? Why the test matters

A new battery only fixes the problem if the battery is the problem. Fit one when the real fault is elsewhere and you're back to square one in days. Here's what we actually check before recommending anything:

Is the battery holding charge?

We load-test the battery to see if it still holds and delivers the power your car needs to start, or whether it's genuinely worn out.

Is the alternator charging it?

If the alternator isn't charging properly it slowly flattens a good battery. We check the charging voltage so you don't pay for a battery that won't cure it.

Is something draining it overnight?

A stuck relay, a boot light or an aftermarket gadget can drain a battery while the car sits. We look for the obvious culprits before condemning the battery.

Is it just age and short trips?

Most batteries last around 4 to 6 years, and lots of short journeys in winter finish them off early. Sometimes the honest answer is simply that it's had its day.

Signs of a dying car battery

A battery rarely dies with no warning. Spot these early and you can replace it on your terms, not stranded on a cold morning. Notice any of them and we'll do a free battery health check.

The engine cranks slowly when you start it

A sluggish, laboured crank is the classic sign the battery is struggling to deliver enough power. It usually gets worse in cold weather.

It's fine one day, dead the next

A battery on the way out can start fine, then have nothing left in it the next morning. Once it starts doing this it rarely recovers.

The lights and dash dim, or the stop-start stops working

Dim headlights, a flickering dash or stop-start that quietly gives up all point to a battery that can no longer hold a strong charge.

A battery or charging warning light on the dash

The battery-shaped light means the charging system needs looking at. It can be the battery or the alternator, so it's worth a proper test rather than a guess.

You keep needing a jump-start

If you've jump-started it more than once, the battery is telling you it's finished. A jump gets you going, it doesn't fix the battery.

The battery is more than five years old

Most batteries last around 4 to 6 years. Past that, a battery can fail suddenly, so it's sensible to test it before it lets you down.

What affects the price

Whatever your car, the price is agreed with you up front and in writing: a £20 call-out, then a clear quote for the work. No hidden fees, no surprise on the bill.

  • The battery your car takes, size and cold-cranking rating vary a lot by model
  • A standard battery, or an AGM/EFB battery for a stop-start car
  • If the battery needs coding to the vehicle (included, but it's more involved on some cars)
  • Same-day or out-of-hours call-outs, where a small surcharge is clearly stated up front

The same job, without losing your day

Same tools, same quality parts, same standard, done at your home or work instead of a workshop. It is James who turns up, every time, so you are not explaining the car to someone new. Where a job genuinely needs a ramp he'll tell you straight, but most of what a garage does, we do on your driveway.

Mobile Car Battery Replacement, your questions

The common ones are slow, laboured cranking when you start, lights and the dash dimming, stop-start no longer working, a battery warning light, and needing repeated jump-starts. A battery over five years old is also more likely to fail suddenly. If you've noticed any of these, we'll do a free battery health check and tell you honestly whether it needs replacing.

It depends mostly on the battery your car takes. A standard small-car battery costs less than a large AGM battery for a stop-start car, and the coding some cars need adds a little time. Our fitting is from £80, plus the battery to suit your car and a £20 call-out, and we confirm the full all-in price before we start. Send us your reg and we'll come back with the exact number, free.

We can't quote another company's prices as they change, and their fitting is usually a separate charge on top of the battery. The honest thing is to compare the full price, the battery plus fitting. Our fitting is from £80, the battery is quoted to suit your car, and there's a £20 call-out, with coding included where the car needs it. We come to you rather than you driving a car with a dying battery to them. Send your reg for your price.

Fitting charges vary and are often quoted separately from the battery itself. With us the fitting, testing and any stop-start coding are from £80, plus the battery to suit your car and a flat £20 call-out, done on your driveway. Nothing starts until you've approved the quote.

It can be, but it's living on borrowed time. Most car batteries last around 4 to 6 years, so a 7 year old one is past the usual lifespan and more likely to fail suddenly, especially in cold weather. If yours is that age we'd recommend a free health check so you can plan a replacement rather than get caught out on a frosty morning.

Yes, that's the main reason people call us. A flat battery almost always happens where the car is parked, so we come to your home or work, test it there and fit a new battery on the spot. You don't have to jump-start it and drive anywhere with a fault you can't see. We can usually get to you the same day.

It's a flat £20 to come out to you, then the agreed price for the battery and fitting on top. Nothing starts until you've approved the quote, and there are no hidden fees. Same-day or out-of-hours visits carry a small surcharge, which we always state up front.

No, coding a stop-start battery to the vehicle is part of the job for us. Cars with stop-start need the new battery registered or the system won't work properly and the electrics can misbehave. Some places charge extra for this or skip it altogether. We include it.

That's exactly what we check before selling you anything. If the alternator isn't charging properly it slowly flattens even a good battery, so a new battery alone won't fix it. We test both the battery and the charging system on site and tell you which it actually is, in plain English.

We're based in Soham and come to you across Ely, Newmarket, Cambridge, Burwell, Fordham, Littleport, Mildenhall, Stretham, Witchford, Haddenham, Cottenham and the surrounding villages.
