Glad to "let me..help you..to help me...to help you... to help me....."
ad infinitum
works for me.
I would suggest just going on the ebay applicable for your region...before you do...copy and paste the title of his ad....change the settings to worldwide and looky-loo ...considering he ships worldwide...he'll pop up with the right input info. So I don't think you need to use ebay.ca nor ebay whatever just use whatever ebay is meant for your geo- region.

Blow- up?!?
Real bad knockoffs possibly...I've never had a prob with any batt. personally..mind you I keep away from supposed high capacity alternatives and real obvious knockoffs.
And Hey... the n800 ain't a pinto man! (the car that is....small minor defect.....had a habit of blowin up reaaallllll gud)
