Battery

Yuasa is the best I have found (my opinion and experience), but I have a FirePower Lithium in my race bike - it is over 7 years old and works fine. Most Yuasa last about 3 to 5 years depending on frequency of use, maintenance and size of battery - the larger the battery the longer it will last.

For a 570, the quad logic battery relocate with larger battery is nice.

Having said that, I was 400 miles away from home when my factory 1 year old battery died (Polaris made by Yuasa)..It was either end our trip early (not cool on first day after 400 mile drive), or Walmart.

Walmart has been in my machine for 3 years, and still working well.

I have same opinion as Latebird, I’ve used Yuasa batts for many years and have been happy with them. My 850 OEM Yuasa AGM batt is 4 years old and going strong, but it’s also maintained with a batt tender Junior.
I think the prob with the 570 is Polaris installed a Yuasa liquid lead acid batt, and its location makes it hard to check and maintain the acid level. If it were me, I’d buy a Yuasa AGM batt, and a Batt tender pig tail long enough to reach the dash or other easily accessible location. install it back into the belly of the beast and never have to worry about it again for 4-6 years.
