Dead CMOS Battery - NEC Powermate portable

Same stuff that combines in the atmosphere (clouds) to form rain made of sulfuric acid - acid rain. My previous post on the exploding lithium on a NiCD port I failed to mention what it did to the traces and open chip legs - corroded the crap out of them and it did indeed stink the hous eup but I always leave my shop window open a crack since I have a habit of using a lot of volatile chemicals for cleaning and such. => -----Original Message----- => From: owner-classiccmp(a)classiccmp.org => [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Joe => Sent: Sunday, February 10, 2002 6:37 PM => To: classiccmp(a)classiccmp.org => Subject: Re: Dead CMOS Battery - NEC Powermate portable => => => At 03:11 PM 2/10/02 +0000, you wrote: => >> => >> It is, perhaps, a stupid question; and I'm familiar with 3 volt => lithiums.
