The battery group sizes to shop for are:
In certain instances you may find a battery that has a number that's off by one digit...like a 47, H6, H7, 93, or 94. Again, price check and look at the specs...sometimes a 49 class size battery may have more reserve capacity than a 95...but the 95 will usually cost more.
Here's some examples of Autozone batteries in the group sizes listed above (not an endorsement, just examples of what's available):
You can also check your battery's voltage if you unlock your OBC and run TEST 9 with the ignition in position 1 (engine not running). The best time to do this is on a cold engine or 2 hours after running the engine...this gives time for any surface charge to deplete (from being recently charged up by the alternator/charging system) and shows a more accurate state of the battery's voltage.
At 11.89 volts...the battery is at 0% state of charge. It can still illuminate interior lights & radio etc from the reserve capacity etc...but may not have enough juice to start the vehicle...and strange electrical gremlins can occur (as others have already stated).
Below are the instructions on how to UNLOCK the OBC so you can run TEST 9. You can also click the link below to see the description of each of the 21 TESTs that can be accessed after the OBC has been unlocked:
