My batteries usually last up to five seasons.
I buy one for an average of $130 CAD from a reputable store like FortNine, acid filled, AGM, don't care. Presently I have an AGM and acid filled batteries in my two bikes.
Batteries are less likely to fail mid-season, and they usually warn the rider about this by, for example, slow cranking. Don’t ignore this first warning sign.
At the start of a new season, I do this simple test without any device: when engine is cold AM I crank 3 times in a row and if the 3rd crank is significantly slower, I replace the battery.
Of course the best and most professional is an AVR test.
