Wow, seems like this is a common practice eh! Im glad I kept it.. Just a matter of sourcing a good priced cell.. awesome... thanks for the input guys..
While im on the subject though, I remember my boss getting these units about 3 years ago.. is this their typical life span ?
Yeah, I have a few 'garbage' ones that work didnt want any more. I think a lot of people dont realize this...
I havnt timed it but I know I replaced them shortly after moving out here in 2017, and I just replaced them before xmas, so your 3 year timeframe (depending on use) seems about right.
