2019 R-27OB starter/thruster and house batteries?

[Blueboy#1]

Hi Jared,

I’m replacing the batteries in my RT27OB and I want to make sure that I am getting the right size and group. The batteries in the house bank are Interstate 31AGM 7 and the starter/thruster battery is the same dimensions and like the same size but a different brand.

Are these good replacements or are there other batteries that I should buy?

I’m not sure why the image I sent is not right but I would appreciate a reply anyway—thanks!

Those are fine to replace, as long as they match the same type of Group 31 AGM battery already used in the boat. The brand is not an issue and is more of a personal preference.

Thank you for your help!
