Best battery for a 1978 KZ1000

I have a Odyssey in a custom battery box for one of my bikes and the first one lasted 7 years. I do remove the battery's from my bikes in the winter and bring them in from the cold northeast.  I also have a stock 1978 KZ1000 ltd and would like a odyssey for that but can not find any parts numbers. What high end battery's do you guys like? I prefer to not replace every 2-3 years.

Motobatt gel in all my Z's. 

LIFEPO batterys in all of my bikes incl. my Kz since 2018. Starts the bike on the first push of the button after the winter hibernation.
Battery capacity loss is only 1% per month and can be installed in any position!
