Our Services

Battery Testing & Diagnosis

Not every starting issue is caused by a dead battery. Our auto electricians provide battery testing services to check whether the battery, alternator or starter motor is at fault. With accurate testing, you’ll only replace a battery when it is truly needed.

Supply & Installation

Matt Gates Automotive stocks and sources reliable batteries for a wide range of vehicles. Our service includes supply, professional fitting and checking connections to make sure your new battery performs properly from the start. We install stop/start batteries, hybrid batteries and standard replacements for all makes and models. All new batteries come with a manufacturer warranty for added peace of mind. Conventional batteries include a 36 month warranty, and stop start batteries have 24 months warranty.

Mobile Car Battery Replacement

If your vehicle won’t start, we can help with mobile car battery replacement and jump starts. Our team comes to you, tests your battery on-site and installs a new one if required. This means you’re back on the road quickly without needing a tow.

Recycling & Disposal

Old car batteries contain hazardous materials and must be disposed of correctly. We recycle and dispose of every battery we replace in line with environmental standards, giving you peace of mind that your old battery won’t end up in landfill.

Why Car Batteries Fail

Car batteries can fail for a range of reasons, including:

01

Heat and cold

High temperatures speed up fluid loss and corrosion, while cold weather slows chemical activity and makes starting harder.

Most car batteries last 3 to 5 years depending on the brand, driving conditions and whether your vehicle uses stop/start technology.

If your battery is swollen, leaking, corroded around the terminals, or no longer holds charge, it’s likely failing and should be replaced soon.

A battery that has gone flat from lights left on can often be recharged. However, if it goes flat repeatedly or fails to hold charge after recharging, replacement is the best option.
