We test before we sell, install with proper torque and terminal protection, register the battery to the vehicle's BMS when required, and recycle your old core for free.

FAQ — Car Battery Replacement

A car battery replacement service tests your old battery under load, removes it safely, installs a new battery matched to your vehicle's specifications, and recycles the old core. Mobile Motors Ottawa does all of this on-site anywhere in the Ottawa region.

Car battery replacement in Ottawa typically costs $180–$380 installed, depending on battery type (flooded, EFB, AGM) and group size. Mobile Motors Ottawa quotes the exact price before dispatch — no call-out fee.

Slow cranks, dim lights at start-up, a battery warning light, a clicking sound at the key, or a battery older than 4 years are strong signs. We test on-site with a professional load tester and show you the readings before recommending replacement.

Premium flooded, EFB, and AGM batteries from major North American and European brands, sized to your vehicle's cold-cranking amps and reserve capacity requirements.

Yes. BMW, Audi, Mercedes-Benz, Volkswagen, Volvo, and Land Rover BMS registration is included when required.

About 20–30 minutes on-site, including load-testing, install, terminal cleaning and protection, BMS registration (if required), and cleanup.

We take the old battery away and recycle it responsibly at no charge. No core fee, nothing sent to landfill.

With proper installation and a healthy charging system, expect 4–6 years. Ottawa winters shorten battery life, so we recommend testing yearly after year 3.
