Battery Replacement & Lighting in Ashford, TW15
Car won't start? Battery warning light on? At Salek Tyre & Mechanic on Feltham Road, Ashford, we test, supply and fit car batteries for all vehicle types — from £79, with same-day service usually available. We also carry out full lighting checks and replace headlights, brake lights, indicators and LED bulbs.
Signs your car battery is failing
Most batteries give warning signs before they fail completely. Look out for:
- Slow engine cranking — the starter motor sounds laboured when you turn the key or press the start button.
- Battery warning light on the dashboard — can indicate a failing battery or a problem with the alternator (charging system).
- Needing a jump start — especially if it has happened more than once, your battery is no longer holding charge reliably.
- Electrical gremlins — erratic behaviour from the radio, windows, central locking or interior lights can be caused by low battery voltage.
- Dim headlights at idle — if lights brighten when you rev the engine but dim at idle, the alternator or battery may be struggling.
- Battery age over 4 years — even without symptoms, a battery approaching 5 years old is worth testing. Most fail between 3 and 5 years.
- Swollen or corroded battery case — visible corrosion on the terminals or a bloated battery casing are signs it needs replacing immediately.
Cold weather is the biggest killer of weak batteries. A battery that copes in summer may fail completely on a cold winter morning. If your battery is over 3 years old, get it tested before the temperature drops.
Battery testing and replacement at our Ashford garage
We use a professional battery tester that checks cold cranking amps (CCA), state of charge, and internal resistance — giving a definitive verdict on battery health, not just voltage. This is more accurate than a simple voltmeter check.
If your battery needs replacing, we carry a range of batteries covering most common vehicles. We fit the right battery for your car's specification — including AGM (Absorbent Glass Mat) batteries for vehicles with start-stop systems, which require a specific battery type. Fitting a standard battery to a start-stop car damages both the battery and the vehicle's charging system.
Alternator testing
A flat or failing battery is sometimes caused by a faulty alternator — the component that charges the battery while the engine is running. If your battery keeps going flat despite being new, the alternator may not be charging it correctly. We test the alternator output as part of our battery diagnostic at no extra charge.
Lighting checks and bulb replacement
We carry out full lighting inspections and replace all types of bulbs:
- Headlights (halogen, HID/xenon, LED)
- Sidelights and daytime running lights (DRL)
- Brake lights and rear lights
- Indicators (front, rear and side repeaters)
- Reverse lights
- Number plate lights
- Interior and boot lights
A blown bulb is an automatic MOT failure and is also illegal while driving on public roads. Most bulb replacements can be done while you wait and take under 30 minutes.

Frequently asked questions — battery & lighting
How do I know if my car battery needs replacing?
Slow starting, a battery warning light, needing jump starts, or a battery over 4 years old are all signs. Bring your car in for a free battery test — we'll give you a definitive answer with a proper diagnostic tester, not just a voltmeter.
Do you offer same-day battery replacement?
Yes — same-day fitting is usually available. Call us on 07341 216705 and we'll confirm stock and availability. If we don't have your battery in stock, we can typically source it within a few hours.
Is a blown bulb an MOT failure?
Yes — any non-functioning headlight, brake light, indicator, or number plate light is an automatic MOT failure. It's also illegal to drive with broken lights. Most bulb replacements take under 30 minutes while you wait.
My car has start-stop — does it need a special battery?
Yes. Start-stop vehicles require an AGM (Absorbent Glass Mat) battery, which handles the much higher charge and discharge cycles that start-stop systems demand. Fitting a standard battery to a start-stop car will damage it quickly. We always fit the correct battery type for your vehicle.
