This is more hardware related so I do not know if you can answer. Just thought I would check with you to see if you have an opinion.
I have my computer and monitor plugged into a UPS. Due partly to where I have the router and modem located, I had them plugged into a second older UPS.
The router and modem were plugged into a APS UPS ES 650 unit that I bought in September of 2007. I initially used in for my computer and monitor. In April of 2012 I bought a new one for my computer , monitor and printer (with printer plugged into a surge only outlet). I then plugged my modem and router into the older UPS.
The older unit is over 8 years old. I think either the battery or the unit itself is dead. Right now the modem and router are just plugged into a surge protector strip. I am thinking I would be better off going ahead and getting a new smaller UPS for the modem and router rather than trying to get a battery for the old unit.
(I am not even sure about replacing the battery)
I just curious as to what you think - get a new unit or a new battery.
If I decided to get a new one for router and modem, I am looking at this onehttp://www.amazon.com/APC-BGE70-Back-UPS-3-outlet-Uninterruptible/dp/B00KH07WRC/ref=sr_1_9?s=pc&ie=UTF8&qid=1456708198&sr=1-9&keywords=battery+backup
It is only 2 prong -which my current router and modem are 2 prong. Just do not know it hat applies to all of them , when I have to get another , will it likely be 2 prong.
I think I will go ahead and order the one I posted above. Not sure if it is the right thing or not, but it appears to have pretty good revies bor the mostpart - and is APC, so , it think it should be ok.
