Using different battery for RTC on the Beagleboard
I need to have correct system time and date for my Beagleboard (rev C4, on Ubuntu 11.10), in which the board will not be connected to the internet or any other input device (aside from a webcam). The Beagleboard's service manual recommends using the VL-1220/VCN battery by Panasonic-BSG, which is only available from Digi-key at the moment.

I'm pressed for time for completing a project I'm working on and it is imperative that the system time is correct. My question is: Can I use any other Lithium battery (3v at different capacities) connected to the board, safely?
