We've had ours for maybe 6 or 7 years (this is our 9th season, and we started with NXT)?  We are just starting to experience intermittent problems; though no show stoppers.  We did purchase a second battery this year as a backup.

Any experience on how many years these battery last. We bought a new one last season. It’s working ok so far this year.  We are debating whether to buy new battery this year. Any suggestions ?

Thanks,
