Micro Snort pump specs - voltage question

[Slats]

Mike and David,
the sticker on the pumps says 6V - I have been running at 7.2v for sometime with no (known) problems. I note the spec below says * Rated Voltage DC3-7.2V on your pumps page. But wondering why the sticker says 6v.
I take it 7.2v remains to be ok?
Thanks

John

Yeah David I get it 7.2v is fine- from God to the king of sarcasm you speak my language....but sarcasm aside - I am puzzled by the pumps sticker of 6v. Usually I find labels like that are the manufactures max voltage, or is this a case of manufacturers being overly cautious?

OK, I've had my fun.

Seriously: I can't speak to what this particular Chinese firms criteria is as to voltage tolerance and how it's applied to their labeling. All I know is that I've run these pumps at a voltage as high as 11.1-volt (limited duty, of course) with no apparent ill effects. So, I'm comfortable running this pump-motor at 7.2-volts all day.

(crackle of thunder) I HAVE SPOKEN, SO LET IT BE WRITTEN!
