RAM Battery Replacement – Mobile Heavy-Duty Service Across Canada

Onsite battery replacement for RAM 1500, 2500, 3500, and EcoDiesel models. Fast, certified mobile service with OEM-grade batteries available across 50+ Canadian cities.

RAM trucks are built for power, performance, and durability — but even the toughest vehicles need a reliable battery to stay running strong. Whether you're hauling, towing, or commuting, a failing battery can leave your RAM stranded. That’s why MobileBattery offers expert RAM battery replacement delivered right to your location.

We install the correct battery group size and CCA-rated batteries for gas, diesel, and hybrid RAM models — all done by certified technicians with full warranty coverage.

Why RAM Battery Replacement Requires the Right Approach

RAM trucks come equipped with high-load electrical systems, especially in trims with:

  • Diesel engines (Cummins, EcoDiesel)

  • Dual battery setups in heavy-duty trucks

  • Start/stop technology in newer 1500 models

  • Winches, LED lighting, and trailer brake systems


Incorrect battery installation or using the wrong group size can cause:

  • Poor starting performance

  • Malfunctioning electronics or sensors

  • Shortened battery lifespan

  • Voided factory warranties


Our team ensures the right battery, safe installation, and system verification — all at your location, on your schedule.


RAM Models We Service

We replace batteries for all RAM trucks, including:

  • RAM 1500 (Classic, Big Horn, Rebel, Laramie, Limited)

  • RAM 2500 & 3500 Heavy Duty (Gas and Cummins Diesel)

  • RAM EcoDiesel models

  • RAM ProMaster and ProMaster City

  • RAM TRX and off-road/towing variants


From light-duty to commercial fleet trucks, we have the tools and battery inventory to get you back on the road quickly.


Signs Your RAM Battery Might Need Replacing

  • Slow cranking or clicking noise during engine start

  • Dim headlights or flickering interior lights

  • Dashboard warning lights (battery or alternator symbol)

  • Engine start/stop system malfunction

  • Battery is over 3–5 years old or corroded


We begin every visit with a free on-site battery and charging system test to confirm whether a replacement is necessary.


Common Battery Group Sizes for RAM Trucks

RAM trucks require robust batteries with high cranking power, especially for cold weather and towing. We carry:

  • Group 94R (H7) – Used in many RAM 1500 gas models

  • Group 65 – Common in older RAM 1500 and V8 configurations

  • Group 49 (H8) – Seen in some RAM 2500/3500 trims

  • Group 31 & Dual 94R – Used in RAM 2500/3500 with diesel engines (dual battery systems)

  • AGM Batteries – Required for start/stop or higher electrical loads


Our technicians confirm your battery requirements using the VIN or existing battery specs.


Our RAM Battery Replacement Process

Step 1: Onsite Testing

We begin with a full battery and alternator diagnostic to ensure a replacement is needed.

Step 2: Correct Battery Selection

Based on your RAM model, engine size, and electrical load, we choose the correct group size and battery type (standard or AGM).

Step 3: Safe Removal & Installation

We remove the old battery, clean the terminals, and install the new battery securely to OEM specs.

Step 4: Dual Battery Sync (if applicable)

For diesel or heavy-duty models with dual setups, both batteries are tested and replaced in sync if needed.

Step 5: System Check & Battery Recycling

We test electronic functions (lights, radio, trailer power) and responsibly recycle your old battery.
