I have purchased batteries from Midnight Sun here in Yellowknife and they are absolutely no good. 

The cheap knock offs of UPS batteries that Midnight Sun is selling won't get you half the amp hours they are rated for and for some reason, they actualy weigh less than competing brands of equivalent batteries. I notified them of this and they did nothing about it.

They intend to continue ripping off customers wtth deficient batteries thinking no one will test them.
