Mods if this isn't in the correct place I apologize and please move it where it belongs.
I have built a nice little AP+Captive Portal for my neighborhood (condo townhouses, lots of houses in range), works great, not stellar range mind you but that will be fixed later. It lives in my attic and for fun I would like to give it a battery backup (also due to it taking for freaking ever to boot up and having issues when it reloads).
Materials I have:
12v 4a lead acid battery
Pico-PSU and 12.65v 5a adapter
18w PC (measured at idle with el-cheapo power measurement dealy)
Sh!t ton of misc electronic parts for battery backup solution
couple Toshiba 15v laptop adapters for funzees
Idea is, I want to use the battery as a backup when my power goes out (which is about 3 times per week, stupid Ottawa Hydro). The 12v adapter can supply 12.65v, which should put the battery at 80 to 90-ish percent capacity. I think. Just needs to work for 1-2 mins max while waiting for power to come back up. Thought about using 10 or so nimh's (I have a battery addiction, so there are probably 30-40 AA's kicking about) but I'm unsure if they can handle the 1-2 amp draw.
I would love to just chuck the battery in parallel and call it a day, but I am going to assume this won't work, or will kill my gear, which would not be exciting. So I'm asking if anyone has ideas how to make this work, without things going 'splodey.
