Danny,
I know you like your big Power Sonic batteries, but I'm curious if you've tried gel batteries.  Their longer life is attractive.

My old Power Sonics lasted a little over 8 years.

I replaced them with a similar battery from our local golf cart shop. It was their private label house brand model. So far so good.

8 years?? :o  Ok, I'm impressed.  My smaller batteries are good for 3-4.

I can't speak to the gel batteries, but like Danny, my own Powersonic PS-121000U also lasted 8 years - Jan/2014 to Jan/2022.  (I have 5 devices on it, split between 5V, 7.5V, 9V, and 12V, but I suspect the total current draw is pretty low.)  I wonder if it might have gone longer if I'd been better about running the reconditioning cycle on the CTEK 7002 charger occasionally.  I replaced that battery with the exact same model and now have a reminder on my phone to run the recondition cycle every 6 months.

Another key is to never discharge them to below about 12.5 volts.
