I have used this battery for at least 10 years with great results, but I change to a new one every three years. They are the best AGM I have found for a ST1300.

However, I am going on a trip next week and am taking a leap of faith with a lithium battery since my current PowerSonic AGM is now three years old, but working fine.
This battery appears the be identical to the Scorpoin "Stinger". I have a Stinger in my Ducati, and it works great. Let's see how well this one works in my ST.
