Possible MH Engine Battery with Amp Hours Too? UPDATE

My idea with the OP battery is no good, as pointed out by Mex, regardless of the sticker numbers.

Land-yacht has it right with his AGM using it for both jobs in his small RV.

BTW you can't just use a 24 in there instead of OEM. They have pos and neg attachments on top that add height, as the new way of doing things. So that is why the OEM batt is so low. Same thing in our Chev Sonic. The wires are too short to reach the posts in a taller size regular 24. They are out to get you! :( Not an RV problem though.
