The recent email from Sonice reminding me that my phone won't work in a power outage has me working again to solve my battery backup problem. We purchase the PS18L UPS when we did our installation. This is good for ~8 hours and was all that was offered at the time. Now they offer the PS36L, which is good for up to 24 hrs, but only to new customers. Does anyone know where I can buy the PS-36L UPS at retail? It is not on Amazon, not on eBay, and every internet supplier I've contacted doesn't sell retail.
I'm not interested in getting a traditional UPS that would convert 110 to 12v, 12v back to 110, and then the ONT power supply would convert 110 back to 12v.
Eventually I'll need to do something. The battery in the PS18L will need to be replaced in a few years. I don't know why Sonic won't sell the UPS or even just the replacement batteries to their customers.
So, to wrap up this rant, does anyone know where I can buy a 12v only UPS that will last ~24 hours?
Thanks
