Nissan Versa 12V Battery Size and Replacement: What Fits a 2012 Versa
The short answer
For a 2012 Nissan Versa, parts catalogs most commonly list a Group 35 12V battery. Treat that as a starting point, not a final answer. The 2012 model year included two different Versa designs, and no confirmed fitment data was supplied for this article, so you should verify the size on your own car before buying.
A battery group size is an industry code that sets the case dimensions and the position of the positive and negative terminals. If the group is wrong, the battery may not fit the tray or hold-down, or the cables may not reach the correct posts.
Why the 2012 model year needs extra care
In 2012, Nissan sold a newly redesigned Versa sedan with a 1.6-liter engine alongside the Versa hatchback. The hatchback carried over from the earlier generation and used a 1.8-liter engine. Because these are different platforms, do not assume that one lookup covers both body styles. Search by body style and engine, or by VIN where a retailer offers it, rather than by "2012 Versa" alone.
Gap to note: the supplied material did not confirm whether the sedan and hatchback use the same group size, or what original-equipment cold cranking amp rating each one had. Confirm both using the steps below.
How to confirm the right battery for your car
Read the label on the battery currently installed. It usually shows the group size and the cold cranking amps (CCA). This is reliable only if the battery is the original unit or a correct replacement. Check the owner's manual or the maintenance section for battery specifications. Use a parts lookup that asks for body style (sedan or hatchback) and engine (1.6L or 1.8L), or one that accepts your VIN. Compare terminal positions with the existing battery so the positive post sits on the same side.
Ratings to match when choosing a replacement
Cold cranking amps measure how much current the battery can deliver to start the engine in cold weather. Choose a replacement that meets or exceeds the CCA rating shown on the original battery or in the manual. A higher rating is generally acceptable as long as the group size and terminal layout match. Reserve capacity, which indicates how long the battery can run essential loads if the charging system fails, is a secondary comparison point.

Replacing the battery: general sequence
Turn off the ignition and all accessories. Disconnect the negative (black, minus) cable first, then the positive (red, plus) cable. Remove the hold-down clamp or bracket, then lift the battery out carefully because it is heavy. Clean any corrosion from the cable ends and the tray. Install the new battery in the same orientation and secure the hold-down. Connect the positive cable first, then the negative cable, and tighten both firmly. Start the car and check that it runs normally. Reset the clock and radio presets if they were cleared.
Old lead-acid batteries should be returned for recycling rather than thrown away. Many sellers accept them when you buy a replacement.
When a new battery may not be the fix
If the car still starts slowly or the battery drains again soon after replacement, the cause may be the charging system, corroded connections or a parasitic drain. A parasitic drain is something that keeps drawing power while the car is off. Having the alternator and battery tested can help you avoid buying a second battery you do not need.
