The 2018 Ram 1500 uses a standard 12-volt lead-acid automotive battery, typically maintenance-free. It powers the starter and the truck’s electrical system and is not a lithium-ion or high-voltage hybrid battery.
Battery type and configuration
Below are the core characteristics of the stock battery for most 2018 Ram 1500 trucks, with notes on variations by trim and market.
- Type: 12-volt automotive battery (lead-acid)
- Design: sealed, maintenance-free, typically VRLA (valve-regulated lead-acid)
- Function: provides starting power and supports the electrical system; recharged by the alternator once the engine runs
- Variations: some configurations may use an AGM (Absorbent Glass Mat) option or different CCA ratings depending on trim/engine; verify exact specification for your vehicle
In short, the standard 2018 Ram 1500 battery is a 12-volt lead-acid unit, most often maintenance-free. Exact model details vary by trim and market.
Context for the 2018 model year
Notes on technology evolution
The Ram 1500 lineup evolved into 48-volt mild-hybrid eTorque technology starting with the 2019 model year, which changed the way the electrical system consumes power. The 2018 model did not include the eTorque system, and relied on a conventional 12-volt battery for starting and electronics.
Maintenance and replacement considerations
If you are maintaining or replacing the battery on a 2018 Ram 1500, keep these guidelines in mind:
- Expect a typical lifespan of about 3–5 years under normal usage; battery age is a key factor in performance
- Check for signs of weakness: slow cranking, dim lights, or frequent electrical faults
- When replacing, choose a battery with equal or higher cold-cranking amps (CCA) and reserve capacity; ensure proper fitment for the engine bay and positive/negative terminal orientation
- Clean corrosion from terminals and apply a protectant; ensure clamps are tight
Regular inspection and timely replacement helps prevent starting problems and electrical issues in the Ram 1500.
Summary
The 2018 Ram 1500 uses a standard 12-volt lead-acid, maintenance-free battery. While most trims use this conventional setup, variations can occur by market or configuration. For precise fitment and specifications, consult the owner's manual or a dealership, especially if you’re comparing to the 2019 model year which introduced the eTorque system.
Can I use a group 24 battery instead of 35?
Group-24, Group-27
The Group 24 and 27 Batteries are mostly found in older American Cars, and some Hondas, GMs and will be often used in boats. They are basically the same size except for length. Our Group-35 can be used in place of a Group-24; it is only 1-inch shorter left to right dimensions.
What is the best battery for a Dodge Ram truck?
