When a Toyota Camry is slow to crank or the dash lights flicker, the 12-volt battery is usually the culprit. Most Camrys use a Group 35 battery, and swapping it yourself is a 20-minute job. Here is the group size, cost range, and how to do the replacement.
| Model / Years | Group size | Typical CCA | Part cost |
|---|---|---|---|
| Camry gas 2012-2025 | Group 35 | 550-650 CCA | $150-$250 |
| Camry gas 2002-2011 | Group 35 | 550-640 CCA | $150-$240 |
| Camry Hybrid 12V aux | Group 35 or aux | 410-540 CCA | $150-$260 |
The great majority of Toyota Camry models use a Group 35 battery. This is the standard Japanese-fit case size, and it is widely stocked at any auto-parts store. Hybrid Camrys have a separate small 12-volt auxiliary battery in addition to the high-voltage traction pack, so confirm your trim before buying.
Aim for a battery with roughly 550 to 650 cold cranking amps for reliable starts in cold climates.
A quality Group 35 battery typically runs about 150 to 250 dollars for the part. Installed at a shop or dealer, expect roughly 200 to 350 dollars with labor. Doing it yourself saves the labor entirely, and many parts stores will test and install a battery for free.
Turn the car off and open the hood. Loosen and disconnect the negative (black) terminal first, then the positive (red). Remove the hold-down bracket, lift out the old battery, and set the new one in the same orientation.
Connect positive first, then negative, and tighten the hold-down. Reset the clock and any preset settings. On some models the power windows need a brief re-initialization.
Watch for slow cranking, dimming headlights at idle, a clicking sound when you turn the key, or dashboard warning lights. A battery more than four to five years old that shows these symptoms is usually near the end of its life.
