If your Nissan Altima cranks slowly or will not start, the 12-volt battery is the first thing to check. Most Altimas use a Group 35 battery, the common Japanese-fit size. Here is the group size, cost, and replacement guide.
| Model / Years | Group size | Typical CCA | Part cost |
|---|---|---|---|
| Altima 2013-2025 | Group 35 | 550-640 CCA | $140-$240 |
| Altima 2007-2012 | Group 35 | 550-620 CCA | $140-$230 |
| Altima V6 models | Group 35 | 550-640 CCA | $150-$250 |
The Nissan Altima uses a Group 35 battery across most model years. This widely stocked size is the same one used by many Toyota and Nissan models, so it is easy to find. Confirm the fit by checking the existing battery and tray.
Around 550 to 640 cold cranking amps is appropriate for the Altima's starter and electrical load.
A Group 35 battery typically costs about 140 to 240 dollars for the part. With shop installation, budget roughly 180 to 300 dollars. Many parts stores install this accessible battery for free.
With the car off, disconnect the negative terminal first, then the positive. Remove the hold-down bracket, lift out the old battery, and set the new one in the same orientation.
Reconnect positive first, then negative, secure the hold-down, and reset the clock and radio presets.
Watch for slow cranking, dim lights, a clicking sound at start, and warning lights on the dash. A battery over four years old showing these signs is usually near the end of its life.
