|I've found that they will happily sell you a dead battery just like it was a good one too. Putting it in upside down might also be a reason for missing OP in a good way, it obviously wasn't saving BIOS settings.when it should have been. The side with the numbers/symbols/text should be readable after installation just for the record.|
riider's claim of power thru rebooting cycle but not powered off case while accurate may not apply in the case of backwards battery. Since power is used in conjunction with battery we have to assume that there is a resistor keeping the battery from being overcharged during use and this resistor would then not be able to supply enough current with backwards battery even with power still on reboot. It never was saving that CMOS info but especially not with backwards battery. I'm assuming the OP got what he wanted and left for that reason probably a little embarrassed about upside down battery installation the first time around.
As to second paragraph in #9 in posted link, I have a 97 chaintech that will refuse to boot if you leave it plugged in after shutting down for a good while. The good while part is the power still applied part like in days. Try to reboot and it just fails, no error beeps, nothing, it won't even turn on the monitor - absolute door stop time. Shorting the battery out and priming the empty pump with the power button while unplugged as advised does nothing for it. Tried all that in at least three different episodes. It just takes days of no power at all except for the battery and at some point it will boot again as if nothing was wrong in the first place. But this is probably a fluke case. They still had BIOS bugs they didn't even know of back in 97 yet, and little from then probably even applies to a unit seriously being considered for revival today.
