1142.7How to tell battery rev.PFSVAX::WUENSCHELLMon Jan 27 1997 14:353
    The batteries that failed were marked 6-96 as a date code, but did not
    have a "B01" marked on them.  Since the "B01" batteries came out in
    March of 96, can I assume these batteries are "B01"?
1142.8....is that week or month 6??KERNEL::LOANEComfortably numb!!Mon Jan 27 1997 18:041
    6-96 could be Week 6; we've had one marked 22-96!!
1142.9Week batteries?ALBANY::HOLCKWed Jan 29 1997 10:218
    When the FCO came out last spring the batteries I received were marked
    3-96 REV B01. My understanding was that REV B01 batteries started in
    March 96 so it looks like the "3" is the month. All of the batteries I
    installed(and thats lots of batteries)lately have been either 6-96 or
    8-96. 
    I have never seen any with 22-96....

1142.10formulae lost...sorryTINCUP::RIDGEI don't know where I'm at, but I'm nearly there!Wed Jan 29 1997 14:555
yes mfg has lost the formulae on how to mark
batteries... and therefore the 22-96 should go away..

1142.11Battery rev identificationSSDEVO::THOMPSONPaul Thompson, Colorado SpringsMon Feb 03 1997 18:503
It was during February of 1996 that the vendor introduced the changes that produced
rev B01 batteries.  Therefore, all current batteries dated 3-96 or later are rev
B01's.  Some, but NOT all, of the batteries dated 2-96 are B01's as well.
1142.12Battery shelf life...?ALBANY::HOLCKThu Feb 20 1997 09:5110
    The latest update I have on my IPMT is not to install any batteries
    that are more than 3 months old-from the date stamp on the top of the
    battery. It looks like long shelf life in not a feature with these
    batteries. Batteries that are installed which are over 3 months
    old have a higher failure rate. An order is placed with our logisitcs
    to order enough batteries to update the 28 hsj40's on my site.

    <---- What is an IPMT?  More importantly, could you post a copy
    of it??

1142.14IPMT?ALBANY::HOLCKThu Feb 27 1997 16:2812
    An IPMT (CLD) its the process used to escallate an on-going problem to 
    engineering. Its based in our CHAMP system. The log number for this
    case is E32B13140 and can be displayed using CHAMP. This update
    to our case from engineering was not(at this time)documented in our
    plan. The message came from a conference call a few days earlier.
    
    The bottom line was to replace all batteries with new ones  less 
    than 3 months old...

    re: -1
    
    Thanks, Harry.  Your note was the first I had heard of this.  Because
    of your info I ordered a battery replacement kit specifying that it be
    less than three months old.  Subsequently, I found out that the
    batteries in 60+ HSZ's at one of our accounts here in Dallas were
    replaced recently with batteries that were more or less straight from
    the factory (Date stamped Feb.), and they _all_ worked.  The engineer
    who did the work told me today there has been no infant mortality so
    far. Hopefully, this is the answer we have been waiting 2 years for.

1142.16Re .14SSDEVO::THOMPSONPaul Thompson, Colorado SpringsWed Mar 12 1997 19:573
Engineering did NOT recommend replacing ALL batteries with batteries less than
three months old.  What was recommended was that replacement batteries should be
less than three months old.
1142.17Proactive battery swapsALBANY::HOLCKWed Mar 19 1997 13:369
    You are right,the recommendation was to replace the failing batteries
    with batteries less than 3 months old. Because are mission critical
    customer(s) have been seeing 2-3 battery failures per week lately, we are
    swapping all batteries during scheduled off-peak times rather than
    waiting for batteries to show up failed at critical times.
    Replacing batteries proactively may not be necassary for less critical
    customers...
