Replacement Process and Warranty
At MWorks MOT, Tyres & Bodyshop in London we follow a clear, professional battery replacement process designed to deliver dependable performance and peace of mind. Our procedure begins with a comprehensive battery health check and electrical system test to diagnose the fault, and continues through careful selection, supply and fitment of the correct 12 volt unit. We register the manufacturer warranty on your behalf and responsibly recycle the old battery. Every job is supported by a transparent written quote and post‑fit testing to confirm lasting performance.
Thorough pre-replacement checks
Before any replacement we carry out a systematic battery health check and full electrical system test. These checks include static voltage measurement, load testing to assess cold‑cranking capability, and an alternator/charging system assessment to ensure the vehicle is charging correctly. Results are recorded and used to pinpoint whether the battery alone requires replacement or if a secondary fault exists in the charging or starting circuit.
Selecting and fitting the right 12 volt battery
We stock a broad range of 12 volt batteries to suit modern and classic vehicles, including start‑stop compatible options and specialist units where required. Our technicians match the replacement battery to the vehicle’s OEM specifications — considering capacity, cold cranking amps, physical dimensions and terminal layout — and fit it using safe working practices. For vehicles that require battery registration or ECU coding after replacement we complete any necessary programming to ensure correct system operation. Once fitted we register the manufacturer warranty on your behalf and supply the warranty documentation for your records. The old battery is collected for authorised recycling in line with UK regulations.

Transparent quotes and responsible disposal
You will receive a clear written quote before we proceed, showing parts, labour and any diagnostic fees so there are no surprises. We only fit batteries that meet the vehicle’s specification and will explain any alternatives and their implications for warranty and performance. When replacing your battery we dispose of the old unit responsibly through certified recycling channels, providing a disposal record on request to demonstrate compliance with UK battery waste regulations.
Post-fit testing and warranty support
After fitment we perform post‑fit testing to verify correct voltage under load, charging system operation and reliable starting. We provide a copy of the test results together with the manufacturer warranty paperwork and guidance on what the warranty covers and how to make a claim. Manufacturer warranty terms vary by product; MWorks registers the warranty for you, retains proof of registration and will assist with any warranty enquiries or claim administration. Advice on routine checks and recommended intervals for battery inspection is included to help prolong the life of your new battery.

Battery care that makes a difference
Simple, routine habits significantly prolong battery service life. Avoid frequent short trips where the alternator cannot fully recharge the battery; combine errands into longer runs when possible. Reduce parasitic drains by switching off lights, infotainment and accessories when the vehicle is parked and by checking for aftermarket devices that draw power. Keep battery terminals clean and free of corrosion; a quick visual check and a terminal clean with a suitable brush and protector can prevent poor connections. For vehicles stored for long periods we recommend a maintenance charger or periodic engine runs to maintain charge. Image keywords: battery, terminals, charger
