Car Battery Replacement in Epsom
We test the battery, the alternator and the charging system before selling you anything, then fit and code the correct battery for your car at your address.

Overview
A flat battery is not always a dead battery
Every winter, the first properly cold morning produces a run of cars across Epsom that will not start. Most of those are genuinely worn-out batteries, because a lead-acid battery in UK conditions typically lasts three to five years and cold weather is what finally exposes one that was already marginal.
Selling you a battery you do not need is easy and we would rather not. So we test before we sell: battery state of health and cold cranking amps under load, alternator output at idle and at speed, and a check for parasitic drain where the symptoms suggest it.
Where the battery does need replacing, fitting the correct type matters more than it used to. Any car with stop-start needs either an EFB or an AGM battery depending on specification, and fitting a standard flooded battery to a stop-start car will destroy it within months.
What's included
What a battery replacement visit includes
Diagnosis, the right battery, correct fitting and the coding that most people forget.
Full charging system test
State of health and CCA under load, alternator output, drain if needed.
Correct type and size supplied
AGM, EFB or flooded. Right case size, right terminals, right CCA.
Fitted with memory retained
A memory saver keeps radio codes and stored settings alive throughout.
Registered to the BMS
Without coding, the car charges for the old battery and undercharges.
Terminals cleaned and protected
Corrosion cleaned back, clamps checked, terminals greased and the battery properly secured in its clamp.
Old battery taken away
Lead-acid batteries are hazardous waste.
Step by step
How we replace a car battery on site
Around thirty minutes for most cars, including the testing and the coding most replacements skip.
Describe the symptoms
Slow crank, clicking, dashboard lights dimming, or dead overnight.
Tested before anything is sold
Battery under load, alternator charging output, and a parasitic drain check if the car goes flat while parked.
Correct type fitted
Right type, right case size, memory saver on so settings survive.
Coded in and verified
Registered to the battery management system, then charging output verified.
When to call
Signs your battery is on the way out
Batteries usually give warning.
Slow, laboured cranking
Turning over more slowly than it used to, worst on a cold morning.
Clicking but no crank
Voltage reaching the solenoid, but not enough current to turn it.
Dashboard lights dim when starting
Voltage collapsing under load.
Battery over four years old
Three to five years is typical in UK conditions.
Cost and detail
What determines the battery you need
Fitting the wrong specification is a false economy that rarely lasts a year.
Battery typeStandard flooded for older cars without stop-start.
Case size and terminal layoutBatteries come in standard case codes.
Cold cranking ampsThe CCA figure is the current the battery can deliver in the cold.
Amp hour capacityMatters more on cars with high standing loads: heated seats, big infotainment, aftermarket accessories, lots of short journeys.
BMS registrationMost stop-start vehicles require the new battery to be coded in.
Included as standardTesting, fitting, memory retention, terminal cleaning, coding where required and disposal of the old battery.

Why us
Why have a battery fitted rather than doing it yourself
We test before we sell
Half the cars we are called to for a battery have a different problem.
Coding included
A stop-start car that is not coded in will undercharge its new battery and fail early.
Memory retained
No lost radio codes, steering angle sensor faults, window one-touch relearns or throttle adaptations.
Fitted and secured properly
An unclamped battery moves, chafes and can short.
Awkward locations handled
Under seats, in boot wells, behind wheel arch liners.
Old battery recycled
Lead-acid is hazardous waste and cannot go in a household bin.

Questions
Car Battery Replacement in Epsom: frequently asked questions
Straight answers to what customers ask before booking.
How long should a car battery last?
Three to five years is typical in UK conditions.
Do I need an AGM or EFB battery?
If your car has stop-start, yes, one or the other. EFB suits basic stop-start systems, AGM is required where there is regenerative braking or a heavy electrical load.
What is battery registration and does my car need it?
Most cars built in roughly the last fifteen years with stop-start have a battery management system that tracks the battery's age and adjusts charging accordingly.
Will I lose my radio code and settings?
Not with us. We connect a memory saver before disconnecting the old battery, which keeps the vehicle's modules powered throughout.
My car is flat but the battery might be fine. Can you tell?
Yes, and this is exactly why we test first.
Can you replace a battery that is not under the bonnet?
Yes. Modern cars put batteries under the rear seat, in the boot well, in the wheel arch or behind trim panels, and many have vent tubes that must be reconnected.
Do you replace batteries on hybrids and electric cars?
We replace the 12V auxiliary battery, which is what runs the electronics and wakes the car up, and which is the usual cause of a hybrid or EV that is completely dead.
What do you do with my old battery?
It leaves with us and goes to a licensed recycler. A lead-acid battery is classified as hazardous waste, cannot go in a household or garden bin, and is close to fully recyclable.
