I have a RAID card in my home server and the battery went dead. It's a lithium ion chemistry with the circuits to tell the RAID card miscellaneous information. I could buy another L-Ion battery to solder in there, but I'd rather upgrade to a supercap for about the same price.
My question is. What kind of affects would I get from just soldering a cap in place of the L-Ion pack? Will the charging circuit work? At the end of the day, the cap should be better than the l-ion pack in all regards, right?
Note: The charging circuit limits current to 500mA
