Crazy. I've had this unit for 12 years, still works great 😂
I've actually gotten better results with self servicing the batteries, you can get higher wattage than what OEM is. I actually learned this tactic working at a support gig. YMMV I guess.

I think mine was about 8 years old when it failed like that. It was the original battery, so 8 years is a lot to ask from an SLA battery.
It was in a closet where a return air duct was, when the hvac turned on it blew nasty smells out with a little smoke. I spent like an hour tearing the furnace apart trying to figure out then eventually traced the smell back. Never tripped the circuit breaker just sat there smoldering when the battery pack went dead short internally (pretty common for me).
I was quite impressed.
Lucky it didn't burn anything down 😬 I keep mine under my desk, I like anything with batteries to be out in the open. That can have downsides too though. I had one fail because my dog used it for a bathroom. Can't blame the unit for that though 🤷♂️
8 years is a long time yes 😅 I replace them every 4 years, yay for reminders in my calendar, otherwise I would forget. This one gets pulled apart again in February actually. I wonder how much more the batteries are going to be this time? 😮💨
XD
Yeah I think Im at 4 years on my big units. They're cyperpower units and the batteries are packed in a steel cage you purchase as an assembly. Its like $200/pack iirc so it's not terrible to buy them, but if I can save a few bucks that would be nice.
