The 2016 Ram 1500 uses a 12-volt automotive battery. In most configurations, it’s a standard maintenance‑free lead-acid unit, while models equipped with a factory stop‑start system typically require an Absorbed Glass Mat (AGM) battery. Exact group size depends on the engine and options, but replacements commonly fall in the Group 65, 75, or 78 range with about 700–800 cold-cranking amps (CCA) and roughly 100–120 minutes of reserve capacity.
Battery basics for the 2016 Ram 1500
Understanding the options helps you pick the right replacement for your truck’s drivetrain and climate.
Stop-start vs non-stop-start considerations
Vehicles with factory stop-start systems generally demand an AGM 12-volt battery to handle frequent cycling and higher current demands. Non-stop-start models typically use a conventional flooded lead-acid battery, which is cheaper but still must meet original CCA and reserve capacity specs.
- Non-stop-start setups: conventional 12V flooded lead-acid battery; typical CCA around 700–800 and reserve capacity near 100–120 minutes.
- Stop-start configurations: AGM 12V battery recommended or required; higher CCA and longer RC to cope with frequent starts.
- Common group sizes seen for the 2016 Ram 1500: Group 65, Group 75, or Group 78, depending on engine, trim, and climate.
- Replacement guidance: choose a battery that matches or exceeds the original specifications (group size, CCA, and reserve capacity) and fits the battery tray and cable layout. OEM or reputable aftermarket batteries with equivalent specs are advised.
Concluding: The Ram 1500’s battery is a 12V unit. If your truck has a stop-start system, an AGM battery is typically used; otherwise, a conventional flooded battery is common. Verify the exact group size and CCA/RC specs for your VIN to ensure a proper fit and reliable performance.
How to confirm the exact battery for your truck
Follow these steps to ensure you purchase the correct replacement.
- Check the owner’s manual or the battery label for Group Size, CCA, and RC specs.
- Look at the vehicle’s door jamb or under-hood sticker for battery information or a part number that matches your VIN.
- If your Ram has stop-start, confirm the battery is AGM-rated as recommended by the manufacturer.
- Consult a dealer or trusted parts retailer with your VIN to verify the exact replacement battery.
Tip: Using the correct group size and chemistry ensures proper fit, charging compatibility, and long-term reliability for your Ram’s electrical system.
Summary
The 2016 Dodge Ram 1500 relies on a 12-volt automotive battery. The exact type depends on whether the truck is equipped with a stop-start system: non-stop-start models use a conventional flooded lead-acid battery, while stop-start models typically require an AGM battery. Common replacement group sizes include 65, 75, or 78, with roughly 700–800 CCA and 100–140 minutes of reserve capacity. Always verify the exact specs for your VIN via the owner's manual, door sticker, or a trusted parts retailer, and choose OEM or equivalent replacements.
