Your anecdote leaves out an important piece of the puzzle -- charge
cycles. Are you charging a battery 50 times per year or 1000 times per
year?
Depending on the job, sometimes I charge the batteries daily.
Sometimes once a week (or two). *Average is most likely 75 charges per
year. *
The 18V batteries are XRP series.
Have you been following the best practices listed here?
