Free replacement vs pro-rata

• Free replacement: if the battery fails inside the period, you get a new one at no cost.
• Pro-rata: you get a discount on a new battery that shrinks the longer you have had the old one. Some warranties start as free replacement and switch to pro-rata after a set number of months.

Ask which type you are getting before you buy, and whether the replacement battery restarts the warranty or continues the original one.

What usually voids a battery warranty

• The wrong battery for the car, such as a standard battery in a start-stop car that needs AGM.
• A charging-system fault. An alternator that overcharges cooks the battery; one that undercharges leaves it permanently flat. Neither is the battery's fault.
• Physical damage: a cracked or bulging case, damaged terminals, or a battery that was dropped.
• Deep discharge from a fault in the car, such as a light or accessory left drawing current for weeks.
• No proof of purchase.

Why a dead battery under warranty is sometimes the alternator

Many batteries brought back as faulty turn out to be flat rather than failed: something else in the car stopped them charging. That is why battery makers' testing guidance, such as GS Yuasa's, has the battery recharged and retested before it is judged. A new battery fitted to a car with a failing alternator, or with something draining it overnight, will go flat again. That is why we test the charging system as well as the battery before deciding anything. If it is a drain, read why a car battery keeps draining overnight.

Documents to keep

• The invoice, showing the battery brand and model, the fitting date and your car
• The battery's serial number or date code (printed or stamped on the case); a photo on your phone is enough
• Any test printout given at fitting

How to claim

1. Check the date: is the battery inside its warranty period?
2. Find the invoice and photograph the serial number.
3. Get the battery and charging system tested. Our battery test is free and done where the car is parked.
4. If the battery fails the test and there is no outside cause, the claim goes ahead under the warranty terms.

Is a battery replacement covered by the car's warranty?

Sometimes. A new car's manufacturer warranty often covers the original battery for a limited period, but usually not batteries as wear items after that. Check your car's warranty booklet or ask the dealer. A battery bought later is covered by its own battery warranty, not the car's.
