Apex Auto Spare Parts — Battery Guide
Truck Battery Replacement Guide — By Make & Model
Quick-reference battery group sizes for the most common trucks on Canadian roads
Every truck brand has its own typical battery specification — and they’re not all the same, even across similar-sized trucks. This guide from Apex Auto Spare Parts gives you a starting point for the most common North American trucks, organized by brand. Always confirm against your CURRENT battery’s label before ordering, since trim level and options can affect the spec.
Ford F-150 (2009–2023)
| Most Common Group Size | Group 65 |
| CCA Range | 760–850 |
| AGM Required? | Some EcoBoost trims with Auto Start-Stop — check your label |
| Notes | Earlier 12th Gen (2004-2008) may use different group size — confirm before ordering |
Ford F-250 / F-350 Super Duty
| Gas Engines | Often Group 65 or 78 |
| Diesel Engines (Power Stroke) | Group 31, sometimes dual-battery setup |
| CCA Range | 850–1000+ for diesel |
| Notes | Dual-battery diesel trucks should have BOTH batteries replaced together with matched batteries |
Chevy Silverado 1500 / GMC Sierra 1500
| Most Common Group Size | Group 48 (H6) |
| CCA Range | 730–760 |
| AGM Required? | YES if equipped with Auto Stop/Start (very common on 2014+ trims) |
| Notes | Side-post terminal variants exist on older models — Group 75 dual terminal covers both |
Silverado 2500HD / 3500HD & Sierra HD (Duramax Diesel)
| Group Size | Group 31 |
| CCA Range | 900–1000+ |
| Configuration | Often dual-battery — replace both as a matched pair |
| Notes | Higher reserve capacity (200 min) supports glow plugs and extended idling |
Dodge Ram 1500
| Common Group Sizes | 94R (H7) or Group 65 depending on year/engine |
| CCA Range | 750–850 |
| Notes | Confirm terminal polarity (the ‘R’ in 94R = reversed) against your current battery |
Dodge Ram 2500 / 3500 (Cummins Diesel)
| Group Size | Group 31 — often dual-battery |
| CCA Range | 950+ |
| Notes | Cummins diesels are notorious for needing strong, well-matched dual batteries — mismatched ages cause one battery to fail prematurely |
Toyota Tacoma (2005–2023)
| Most Common Group Size | Group 35 |
| CCA Range | 600–650 |
| Notes | 2WD and 4WD generally share the same battery spec; confirm by trim if uncertain |
Toyota Tundra
| Common Group Sizes | Group 35 (earlier years) or larger depending on V8 trim |
| CCA Range | 650–800 |
| Notes | V8 Tundra trims may specify higher CCA than 4-cylinder/V6 equivalents |
Nissan Frontier / Titan
| Common Group Sizes | Group 35 (Frontier) / larger for Titan V8 |
| CCA Range | 600–800 |
| Notes | Many Nissan trucks share battery specs with comparable Toyota models — confirm by label |
💡 The golden rule: Regardless of what this guide says, the label on your CURRENT battery is the definitive source for your specific truck’s group size, terminal layout, and minimum CCA. Trim level, engine choice, and factory options all affect the spec — even within the same model year.
Dual-Battery Diesel Trucks — Special Notes
- Always replace BOTH batteries together, even if only one tests as ‘bad’
- Use matched batteries — same brand, group size, age, and type for both
- An old and new battery in parallel will charge unevenly, shortening both their lifespans
- Group 31 is the standard size for most dual-battery diesel setups
Frequently Asked Questions
My truck’s trim level isn’t listed here — what do I do?
This guide covers the most common configurations, but the definitive answer is always the label on your current battery. Call us with your VIN and we’ll confirm the exact spec for your truck.
Can I upgrade to a higher CCA than what’s listed here?
Yes, as long as the physical group size and terminal layout match (or you choose a dual-terminal option like 34/78 that covers multiple configurations). Higher CCA is never a problem, only lower CCA than spec.
Why does my Silverado have side-post terminals but the chart says top post?
Some GM trucks use side-post (threaded) terminals instead of top post. Group 75 dual-terminal batteries provide both connection types on one battery — useful if you’re unsure which your truck has.
Is it OK to mix battery brands in a dual-battery diesel setup?
It’s best to use the same brand and type for both batteries in a dual setup, ideally purchased and installed at the same time, so they age and charge together evenly.
Does 4WD vs 2WD affect battery specification?
Generally no — battery specs are typically tied to engine choice and electrical equipment (trim level, Auto Stop/Start, etc.) rather than drivetrain configuration.
