Slee dual-battery tray battery size?

[Pskhaat]

Slee's dual-battery tray is made for "optima" sized batteries. In the group-size parlance, what is this? ~ Group 24? 31?

I am wondering the same thing....going to add the Slee second battery tray soon.

Just measured mine: Looks like 10-1/4"L x 7-3/8" W x 8.5"H is about the max size battery it and the space will accommodate.

Looks like a Group 24 or Group 36. I just had to buy a 9-year Group 36 for another application, so good to know I can use it in the Hundy when the time comes.

FYI: The max height would be to the top of the posts; you might be able to get a little more.
