When I use a 12 volt car battery to supply the router it will not complete the boot-up sequence. Continuously cycles. Works normally with AC powered wall-wart. Voltage is 12.55 VDC. Have tried two different batteries. Any ideas?

"A" != "D". D7000[v1] or D7000v2, or what? Look for "Model" on the product label.

With or without the engine running? Cable length?

That's a little vague. The LEDs flop around as in a normal power-on, but don't get stable, or what?
I've never tried it, so I know nothing, but I'd expect a bare battery to work well. A running engine (generator) might add some potentially troublesome (electrical) noise, but I wouldn't expect it to matter. A sufficiently long cable might make a local filter/bypass capacitor desirable close to the load.
I happened to have handy an adapter cable stub which was deformable into compatibility, so I've now tried it with a D7000[v1]. Worked as expected (although without Internet access). The LEDs look dim outdoors, but that's true with the AC adapter, too. My cheap-Chinese meter said 12.3xV ("x" varied), for what that's worth, with the engine off.
It did take about a minute and a half to initialize (either way).
