Battery Size Group 151R
Group Size 151R Battery: A Compact Power Option for Smaller Cars
If you drive a compact car and need a reliable, budget-friendly battery, the Group Size 151R might be the right fit. It’s a compact 12-volt battery designed to handle day-to-day driving needs, especially in vehicles that don’t require high cranking power. While smaller than many other batteries, the 151R holds its own when it comes to performance in urban Canadian driving conditions.
Specs, Size, and Cost in Canada
Group 151R batteries are compact and lightweight, measuring about 9.38 inches long, 5.06 inches wide, and 8.75 inches high. These batteries typically offer Cold Cranking Amps (CCA) between 370 and 500, Cranking Amps (CA) from 500 to 625, and Amp-Hour (Ah) ratings in the 35 to 45Ah range.
Because of their smaller capacity, they’re more affordable. In Canada, expect to pay between $120 and $170 for a new Group 151R battery, depending on the brand and warranty. Most come with a 2- to 3-year free replacement warranty, giving drivers peace of mind for short commutes and city driving.
Vehicles That Use Group 151R Batteries
Group 151R batteries are commonly found in small Japanese and Korean vehicles, especially:
Honda Fit
Honda Civic (2006 and newer)
Toyota Yaris
Mazda 2
Hyundai Accent and Kia Rio
These vehicles don’t require large batteries, making the 151R a great fit for space and power efficiency. If you’re unsure what group size you need, check your owner's manual or visit our Car Battery Replacement page for help.

How to Tell If Your 151R Battery Is Failing
You can catch battery issues before they leave you stranded. Here are three simple checks:
Slow starts – If your car takes longer to turn over, your battery might be weak.
Voltage reading – A healthy battery should show 12.6V or higher when charged.
Load test – During cranking, the voltage shouldn’t drop below 9.6V.
If you don’t have tools at home, no problem. MobileBattery offers at-home and roadside battery testing across cities like Vancouver, Edmonton, and Toronto.
Battery Life Expectancy in Canada
In Canada’s mix of freezing winters and hot summers, a Group 151R battery typically lasts 3 to 4 years. Smaller batteries often work harder in cold conditions, so testing annually is a smart idea—especially after year two.
