How to Check If Your Battery Needs Replacing

Here are a few ways to check your 124R battery before it fails completely:

Slow start – If your engine cranks slowly or hesitates, that’s a red flag.
Voltage test – A healthy battery should read 12.6 volts or more at rest.
Load test – While cranking, the voltage shouldn’t fall below 9.6 volts.

Don’t have a multimeter? No problem. MobileBattery offers battery testing and replacement right at your home, office, or roadside—saving you the hassle of a shop visit.

Battery Lifespan in Canadian Conditions

In Canada’s cold and varied climate, a Group Size 124R battery typically lasts 3 to 5 years. Cold starts, short trips, and high accessory use (like heated seats and defrosters) can shorten lifespan. That’s why regular checks—especially before winter—are essential.
