The Nissan Altima uses a Group 35 battery. Some 2019-and-newer trims add stop-start, which needs an AGM battery. Read the label on your old battery to confirm the exact fit.
The Nissan Altima takes a common Group 35 battery, so replacements are cheap and easy to find.
The real questions are whether your car has stop-start and how cold it gets where you live. Here is the exact fit and the picks worth buying.

01Best Overall
DieHard Platinum AGM (Group 35)
DieHard
Group 35640 to 680 CCA CCAAGM3 yr free replacement warranty
Start-stop ready with a strong free-replacement warranty, and easy to find. The safe default for a newer Altima.
The Altima uses a Group 35 case with top-post terminals and wants roughly 590 to 640 cold cranking amps.
Group 35 is the spec that must match, a different size will not sit or clamp correctly. Check the label on your current battery to be sure, because trims and years vary.
Flooded or AGM
A standard flooded battery is fine for most Altimas in a mild climate. If your car has stop-start, added on some 2019-and-newer trims, fit an AGM instead.
Stop-start works a battery far harder than normal driving, and a flooded unit will fail early in that role. AGM also copes better with short trips and heavy electrical loads.
How we picked
We ranked only Group 35 batteries that fit the Altima, scored on published cold cranking amps, warranty length, price, and owner-reported reliability.
We do not bench-test batteries, so this is a fit, spec, and value ranking, and a reviewing technician checked the fitment before it went live.
The battery is the easy part of Altima ownership.
The bigger used-car question is the transmission, so read the years to avoid before you buy, and compare it against rivals in the best first cars list.
Frequently Asked Questions
What size battery does a Nissan Altima take?
The Altima uses a Group 35 battery with top-post terminals and about 590 to 640 cold cranking amps. Confirm against the label on your existing battery before you order.
Does a Nissan Altima need an AGM battery?
Only if it has stop-start, which appears on some 2019-and-newer trims. A stop-start Altima should get an AGM, while other Altimas can run a standard flooded battery.
What is the best battery for a Nissan Altima?
The DieHard Platinum AGM is the best overall pick. Step up to the Odyssey 35-PC1400T for cold climates, or save with the EverStart Maxx-35N if your car has no stop-start.
How long does an Altima battery last?
Three to five years is typical, and heat shortens it. Replace a battery over four years old if it is slow to crank on cold mornings.
Why does my Altima battery keep dying?
A parasitic draw from cabin electronics or short trips that never fully recharge the battery are the usual causes. A higher-CCA AGM helps, but have the charging system and draw tested if it keeps happening.
