Re: Cache Battery question

[DrFranken <midrange@xxxxxxxxxxxx>]

That's not correct, the controllers DO charge the batteries. Think about 
what would happen if they didn't, you lose power for a few hours and 
your server goes down. The battery holds the cache during that time and 
of course discharges partially in that effort. When power is restored 
you bring up the system no problem.  If the batteries did not get 
charged by the controller then the remaining battery life might not be 
sufficient to hold up the cache during your next outage.

In addition it is no longer legal to transport bulk batteries of this 
type in the U.S. with a full charge. As a consequence most batteries 
installed are only partially charged and the controller completes the 
charge.
