The Ram 1500 draws heavy current for its V8 starts and accessories, and eTorque models add an auxiliary battery. Most Ram 1500s use a Group 94R (H7) battery. Here is the group size, cost, and how to replace it.
| Model / Years | Group size | Typical CCA | Part cost |
|---|---|---|---|
| Ram 1500 2019-2025 | Group 94R (H7) AGM | 800-850 CCA | $220-$350 |
| Ram 1500 2011-2018 | Group 94R or 65 | 730-850 CCA | $180-$320 |
| Ram 1500 older | Group 65 | 700-800 CCA | $180-$280 |
| Ram eTorque aux | Aux battery | Low CCA | $60-$130 |
The modern Ram 1500 typically uses a Group 94R, also called H7, battery, often an AGM type from the factory. eTorque mild-hybrid models add a small auxiliary battery to support the start-stop and torque-assist system. Older Ram trucks commonly used a Group 65 battery. Confirm the fit by checking your existing battery.
Aim for high cold cranking amps, often 800 or more, to handle the HEMI starter and cold-weather starts.
A Group 94R AGM battery typically costs about 220 to 350 dollars for the part. Standard flooded versions cost less. With shop installation, add roughly 30 to 80 dollars in labor. The small eTorque auxiliary battery is a separate part.
With the truck off, disconnect the negative terminal first, then the positive. Remove the hold-down, lift out the heavy battery, and set the new one in place. If your truck came with AGM, replace it with AGM.
Reconnect positive first, then negative, secure the hold-down, and reset the clock. eTorque models may require servicing the auxiliary battery separately, and some trucks benefit from battery registration.
Watch for slow cranking, dim lights, a clicking start, and warning messages in the display. On eTorque models, an auxiliary battery warning can appear even when the main battery is healthy, which points to the small auxiliary unit.
