After a looooong search through the commuting forum (especially both light related stickies) I still cannot find the info I'm looking for. Perchance someone here knows:

What are the specifications of the sealed lead acid battery that comes stock with the NiteRider Road Rat? I bought a used RR on Craigslist for super cheap, but the guy said the battery had died on him and he threw it out. Obviously, this guy isn't into DIY and recycling. No matter. I've replaced batteries on my NiteRider Classic before, saving the plug end and the capacitor and resoldering on a new battery.

The info I'm looking for is: battery amp hours, dimensions, capacitor size (if it comes with one) and *hope hope* part number for the plug . Has anyone done this proceedure? I simply want to order a similar battery, and hop on down to Radio Shack for a plug and cap.
