How to Check Your Car Battery’s Age
Battery age predicts failure better than anything — and it’s stamped right on it. A Cranbourne West specialist explains.
Reading the date code
Most batteries carry a manufacture date — sometimes printed plainly, often as a code on a sticker or moulded into the case. Common formats: a letter for the month (A=Jan, B=Feb…) plus a digit for the year, or a simple month/year stamp. Some retailers add their own fitted-date sticker, which is the more useful number.
No sticker and no legible code usually means it’s old enough to test anyway.
What to do with the answer
Australian heat is brutal on batteries: 4–6 years is a typical life, less for cars doing short trips. Past 4 years, have it load-tested before winter — a battery almost always fails on the first cold snap after its warning signs (slow cranking, stop-start disabling itself) were ignored.
We load-test batteries free with any service, and fit the correct type (AGM/EFB, coded where needed) when it’s time.
