RE: Cache Battery question

Base controller in the P7 8205 CEC still has cache batteries, (I actually forgot about these, playground LPAR)
Thanks for that tip.

I think so, I play heck trying to find anything on my 'host' lpars under 9.  Work with resources containing cache battery packs in SST.
57CE-001


And I don't think my VIOS lpars have cache batteries either

The newer controllers (5913,etc)  no longer have a cache battery, is this 
correct?

If you have maintenance on the system (even from the third party guys) 
changing the batteries is baked into the price so why do you really care 
how much the batteries are or how long they have a shelf life for?  They 
get swapped every three years anyway.

The batteries are so expensive for two reasons; first transporting them 
has become a real headache since they cannot be shipped by Air with any 
charge at all.  (Technically you're not even allowed to have a second 
battery for your laptop/phone with you on the airplane, yea everyone 
ignores that one.) Secondly these batteries are very expensive to dispose 
of so that has to be taken into account. 

Aside from the mystery about the OP battery degradation (I suspect a bad 
controller card) there's not much point to trying to determine how fast 
the batteries charge or decay.  Besides, IBM already knows all of that. 
Why do you think they put a shelf life on them?

That is a great idea so we can get some clarification. If i find some 
spare time (puh...) i will go on with some older controllers and put in 
some measure cables to see what will happen. As there is not often the 
chance to see the behaviour after an outage, we will simulate this...

At least the modern batteries starting with the power6 boxes are rather 
expensive and have a date after which they should not be used any longer.
This date is current timestamp + 3 years if i remember correctly, 
something like this. Would be strange if (under controlled charging 
environment) IBM do not trust their 250$ batteries only for 3 yrs..
