Follow these steps carefully
Put on safety glasses and gloves before you begin. Park on level ground, shift to Park, set the parking brake, and switch the ignition fully off. These trucks carry their main starting battery here — unlike the heavy-duty Rams, the 1500 does not hide a second battery under the passenger seat.
It monitors charging and must transfer intact to the new battery's negative post — handle with care, never cut or bypass its wiring. Photograph the clamp and connector, and confirm the wiring has slack to move aside.
That sensor rides on the clamp, not the battery — the same clamp and sensor go back on the new battery's negative post. I've seen people try to buy a new sensor with the battery; you don't need one unless its wiring is damaged.
Loosen the negative clamp bolt with the wrench or socket that fits — 10mm or 13mm on these trucks — turning counterclockwise until the clamp loosens. Ease the clamp off the negative post with a gentle twisting motion — do not pry it or yank the sensor wiring.
Open the red cover on the positive terminal and loosen its clamp bolt the same way, then twist the clamp off the post. On some trucks the positive clamp assembly is a multi-piece unit with extra cable lugs stacked on it — keep those pieces in order and photograph them so they go back the same way. Rest the positive cable where it cannot contact bare metal, and inspect both cable ends for corrosion that you will clean before reassembly.
Lift the battery straight up and out with both hands, keeping it level. Set it upright on the ground, clear of foot traffic.
Brush corrosion and grit out of the tray and scrub the inside of both cable clamps with a terminal brush until bright metal shows. Check that the plastic stop is still seated correctly in the tray, then lower the new battery in with the same orientation as the old one so the posts align with their cables. Refit the hold-down wedge against the battery’s base lip and tighten its bolt until the battery cannot rock or slide; a loose battery in a truck tray will hammer itself to an early death on rough roads.
Reconnect the positive cable first, tightening its clamp bolt until snug, then reconnect the negative cable — sensor assembly included — last, making sure the sensor connector is fully seated. Start the truck and confirm strong cranking, then check lights, blower, and wipers.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
