Is it regular lithium batteries? Those things fall off sharply around 3-5 years for most regular charge/discharge use cases, ie an iPhone. Lead acid isn’t great either but I’ve found it is possible to revive some with an electric welding machine. It’s kind of unsafe but does work
Yes it’s just lifepo4 lithium batteries but the technology just keeps advancing quickly. They advertise like 5000-40000 cycles… iPhone is getting discharged to 0% daily.. if you have enough panels you shouldn’t discharge it that much making it last a lot longer
