Car Battery Testing & Replacement: an overview
A weak battery is one of the most common reasons a car will not start — but it is not the only one. A battery that keeps going flat may be fine, while the real problem is the charging system or something draining power when the car is parked.
We test before we replace, so you only buy a battery when you actually need one.
Problems we can help with
- Engine cranks slowly or clicks when starting
- Car will not start after standing overnight
- Battery warning light on while driving
- Battery keeps going flat
- Swollen, leaking or corroded battery
- Electrical items behaving strangely when starting
What we do
We test the battery's condition and its ability to deliver starting current, then check the charging voltage from the alternator with the engine running. If the battery keeps going flat, we check for a parasitic drain — something drawing power when the vehicle is switched off.
If the battery needs replacing, we fit one of the correct size and capacity for your vehicle, clean and secure the terminals, and confirm the charging system is working. Some vehicles need the new battery registered with the car's computer, and we tell you if yours does.

Car Battery Testing & Replacement: frequently asked questions
How do I know if it is the battery or the alternator?
A battery that cannot hold a charge causes starting problems, while a failing alternator stops the battery being recharged while you drive — often with a battery warning light. Testing both is the quickest way to know which one is at fault.
How long does a car battery last?
It varies with the battery, the climate and how the vehicle is used. Frequent short trips and long periods parked shorten battery life. A test shows how healthy your battery is now.
My new battery went flat too. Why?
That usually points to a charging fault or a parasitic drain rather than the battery. We test the charging system and check for drains to find the cause.
