The battery Group Size is H8. After that it is up to your pocket book. You have to make sure the battery is a vented style and comes with a vent kit. The kit is a fitting and rubber hose that runs through a hole in the floor pan to vent battery gases out of the trunk/boot.

 

Just curious. Why the need for a vented battery if sealed ones are available?

 

Sealed AGM batteries will still vent in an emergency (like an internally shorted cell), even though they don't vent at all during normal operation like flooded cell batteries. The AGM battery I bought for my car (https://www.walmart.com/ip/EverStart...up-h8/40647529) still has the vent hole on the side for the vent hose.
