Re: Battery Cache

[Pete Helgren <Pete@xxxxxxxxxx>]

The weird thing for us is that WE just did this 4 months ago.  Either we 
are all getting bad batteries from different sources or something is up !

I just "cycled" mine this weekend (unplugging, testing, and 
re-connecting) and all is well again.  The system is on lease and is 
going back the end of August so not much risk in our approach.

Strange "coincidence" though.
