I need to replace the battery on my U800.  I know it's 12V 30Ah, per manual, but are some makes better than others?

It's been hit or miss for me. Wal-Mart batteries have been the worst. Yusa have been ok but I habe had some of the off brand ones last too.  Some have a year warranty on them. If they are not far for you to send back, might be ok. I find if they last a year, they will make the distance.

I have had good luck with the Shorai Lithium-Ion battery in my Brute. I think because with no lead or acid it doesn't have anything to slosh around off-road or parts to take a beating. But...they don't give those away. I think one for these would run in the 220 range. Paid 170 for the one in my Brute like 5 years ago. Still spins the starter like it's hooked up to ..way more then 12 volts. You do have to be careful  when charging them or maintaining them.

Thanks for the input.  I looked at a lithium battery as well, but the charger I have would not work with it, so that was a no go.
I ordered a Scorpion AGM for $95 shipped.  It gets pretty hot here in Texas, so I'm hoping the AGM will hold up better than the wet cell.
