Step-by-Step Instructions
Follow these steps carefully
1
Park, power down, and open the hood
Park flat, set the parking brake, switch the engine off. Turn off headlights, blower, and unplug chargers; pop the hood. Note: gasoline Camrys only — on hybrids the 12-volt battery lives in the trunk, so check your manual if yours is a hybrid.
2
Find the battery in the engine bay
On gasoline Camrys, the battery sits low in the front corner of the engine bay. Positive wears a red flip-up cover over the plus terminal; negative is black with a minus. Snap a phone photo of the routing before loosening anything.
3
Disconnect the negative terminal first
Loosen the negative terminal nut with a 10mm socket until the clamp frees, then twist the cable end side to side and lift it straight off — never pry with a metal tool, which can crack the post seal.
4
Flip up the red cover and disconnect the positive terminal
Flip the red cover up, loosen the positive clamp nut with the 10mm socket, and twist the cable end off. Keep it off the battery, bare metal, and the air filter housing beside the battery — and keep the two cable ends separated.
5
Locate the 12mm hold-down bolt and confirm the battery is free
The hold-down bracket at the battery's front base takes a 12mm bolt — reach it with a socket extension. Rock the battery to confirm it's free; forcing a clamped battery can crack the tray or case.
6
Lift out the old battery
Lift the battery straight up with both hands, keeping it level — it weighs about 40 pounds. Install the new battery facing the same direction, matching size and terminal positions, then refit the hold-down and snug the 12mm bolt.
7
Reconnect positive first
Reconnect positive first: tighten the 10mm nut until the clamp won't rotate by hand, flip the red cover down. Check the manual for radio-code or window resets, and recycle the old battery at a parts store.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Panicking when the engine stumbles or dies on the first start after reconnecting — just restart it; that is normal on these Camrys.
- • Using a 10mm socket on the 12mm hold-down bolt and rounding it — check the size before applying force.
- • Forgetting to flip the red positive cover back down, leaving the terminal exposed.
- • Installing the new battery without matching the old one's label — wrong terminal layout means the cables will not reach.
