Did you know that the average agm battery has an average service life of about 1500 full charge cycles ?
The average lithium is about 2500 full cycles

The average sodium battery 4000 full cycles

Why does this matter
Your 230 dollar harley agm battery is probably good for 3to 4 years of normal use
A good lithium in the 300-500 dollar range should last 4 to 5 years
A good sodium battery 7-8 years expected life

All batteries fall off in perfromance over time , capacity drops , discharge rates are reduced.

But spending a few bucks more on a battery will help you have less problems over the long run
