Normal driving will not restore the battery to a reliable level of charge. Instead, it should be recharged using a suitable multistage battery charger – and allow up to 48 hours for a flat battery to recharge.

What is sulphation in car batteries?
Sulphation is the chemical reaction between the sulphuric acid and the lead plates within a battery. When a battery discharges, ‘sulphate’ crystals form on the plates, which reduces the battery’s capacity. Batteries kept in a poor state of charge will form ‘hard’ sulphation – this causes permanent damage and can void your warranty. To reduce sulphation, fully recharge the battery as soon as possible.

Why is it important to check my car battery?
Your car battery may look good on the outside, but what’s going on the inside it can be a different story. If your battery is feeling sluggish to start or you can see any visible wear, this can indicate you may need a new battery. We recommend having your battery checked and tested by a professional.

When do I need to replace my car battery?
Many times the first hint of a battery problem shows up during the starting process.
If the car battery is too weak to provide a sufficient voltage to the starter, you'll hear a distinctive clicking sound and the engine won't crank over. This clicking indicates that the battery is not fully charged.
AA Battery Service can perform a battery test to determine if the battery needs to be replaced. Sometimes a faulty alternator will be the culprit, but other times the test will reveal a weak battery not capable of holding a charge. This means the battery must be replaced.
