I could not find any information regarding the required battery size for the Nissan Altima Hybrid. After seeing that Amazon lists the size as either Group 35 or Group 34, I took the plunge and bought this battery at the local automotive store (minus 35% off coupon & $25 Rebate). Installation was simple. No modifications to the terminals was necessary. The vent tube fit right onto the Bosch vent.

Bosch Platinum Series AGM Group 34. The battery was not tall enough so I had to put some washers under the hold-down.

Any issues so far? Do you have the NAV package, and if so, does everything work fine?

 

No issues so far. I don't have the Nav package.

Car has 128K miles and still going strong.
