In my experience, with a 16MB Silicon Disk, the battery can only maintain the contents for about 1 day. Now that memory is very old, and I can't remember if I did a careful test, so it might be as long as 3 days, but the battery life was very short when the machine was off, and the Silicon Disk was large.
If you have a large Silicon Disk, leave the Outbound plugged in all the time. That's really what Outbound recommended any way. Lead acid batteries often die if they are discharged completely.
As Unity stated, that LEM is wrong. Also, the OS compatibility is wrong.
On my list of projects which I will never get to, but have nevertheless tried to buy parts for, has been to build some 30 pin SIMMs with a PLD and SRAM to see if replacing the CMOS RAM with SRAM will lower the power consumption significantly and increase the battery life.
