WTB: 570 battery

[fuscob]

I saw a couple other "WTB" threads for 570 batteries with no responses, but I figured I'd give it a try anyways

Does anyone have a working battery (doesn't have to be in perfect shape, just enough so I can leave it off of AC power for a bit) for a 570? I just picked one up (for free ) and I'd love to make it a complete system.

Thanks in advance!
