Battery Size Group 36R

Group Size 36R Battery: A Compact Powerhouse for Daily Canadian Drivers

The Group Size 36R battery is a compact yet capable option, ideal for older cars and smaller vehicles that don’t need a large or high-output battery. It’s not as common as some other group sizes but plays an important role in powering vehicles that require a reversed terminal layout and a compact footprint—especially in colder Canadian conditions where starting power matters.

Size, Specs, and Cost in Canada

Group 36R batteries are 12-volt and typically measure around 10.25 inches long, 7.06 inches wide, and 8.88 inches high. These batteries are built for vehicles with moderate power needs and specific terminal layouts.

Typical specifications include:

• Cold Cranking Amps (CCA): 550 to 650

• Cranking Amps (CA): 675 to 800

• Amp-Hour (Ah): 50 to 60Ah

In Canada, a Group 36R battery will usually cost between $150 to $210, depending on the brand and warranty. Most offer a 2- to 3-year free replacement warranty, which is standard and practical for everyday drivers.

Vehicles That Use Group 36R Batteries

This battery group is primarily found in older Ford, GM, and Chrysler vehicles that are designed with reversed terminal positions. Common vehicles include:

• Ford Taurus (early 2000s models)

• Mercury Sable

• Buick Century

• Chevrolet Celebrity

• Oldsmobile Cutlass

Battery Lifespan in Canadian Driving Conditions

On average, a Group Size 36R battery will last 3 to 5 years in Canadian climates. With regular city driving, cold winters, and short-distance trips, batteries wear down over time. Regular testing after year three is the best way to avoid being caught off guard.
