    I intend to operate a set of APs in a large application area where wired electrical power is sporatic at best, and as such intend to operate them of standard rechargable batteries. Does anyone have any experience in these matters that can offer advice, or know where I can go to read up on this or similar setups?

    Also, Assuming one uses a WRT54G, and loads third party firmware to boost the signal to 50 or 100mW as opposed to the standard 18, what exactly is the electrical demand from such a device? Is it simply 82mW more than normal, or is more demand placed on other parts of the device as well?

    Get a good UPS.
    Car battery lasts about 2 days with a WRT on max power.

    You have to deal with about 3 - 6W, depending on router model. The 250mW of the wireless makes virtually no difference on power requirements, it just heats up the radio it seems.

    If you can charge a 12V 7Ah lead-acid battery for about 8 - 12h out of 24 hours at maybe 14.5V, you should be OK. I'm not sure what the impact on the life of the battery would be, as I think 12V lead-acids like to be charged at not more than 13.8V.
