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.

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.
