The alternator charges your battery and powers your vehicle’s electrics while the engine runs. A failing alternator is one of the most commonly missed faults – drivers often replace the battery repeatedly without realising the charging system is the actual cause. Batteries and More tests your alternator’s output on-site using proper diagnostic equipment, then either refurbishes your existing unit or supplies and fits a new one.
A battery stores charge; the alternator generates it while the engine runs. If your battery keeps dying shortly after being replaced or jump-started, the alternator is often the real cause - we test for this on-site.
Where possible, yes. We refurbish alternators rather than defaulting straight to a new unit, which can save you money.
Your battery will eventually be unable to hold charge, and you risk being stranded with a vehicle that won't restart.
