Know what you’re replacing.
A slow crank, clicking, or electrical glitches on start-up usually mean your Ram 1500 needs a new battery. Most of these swaps take about 30 minutes. If your vehicle has Auto Start-Stop, it needs an AGM battery. On eTorque (mild-hybrid) trucks there is also a separate 48V battery pack behind the rear seat — never disconnect or service it. This guide covers the main 12V battery under the hood.

A little preparation first.
- Match the group size and type on your old battery's label, or look it up by VIN at a parts store.
- Engine off, key or smart key away from the vehicle, glasses and gloves on.
- Note radio presets; some settings may reset.
One step at a time.
2Disconnect the negative (–) terminal first
Loosen the black terminal and move the cable away from the post. If there's a sensor on the negative clamp, disconnect at the clamp, not the sensor plug.
3Disconnect positive and remove the hold-down
Remove the red terminal, then unbolt the hold-down with a socket and extension.
4Lift out the old battery
Lift straight up with both hands — expect 40–55 lb — and keep it upright.
5Install the new battery
Seat it the same way, refit the hold-down, connect positive first, negative last, and tighten both clamps.
