NOOK has a 10 day battery life, assuming 1 hour per day usage.
NOOKColor has a much shorter battery life.
The NOOK charging cable (and I suspect this is what Best Buy sold you) shouldn't be used with NOOKColor because it doesn't provide enough power to charge NOOKColor's battery.
You may need to go to B&N to see if they have the proper charging cable.
I don't think it's the NOOKColor; I think it's the cable.
First of all, what you are describing as battery use is way above normal. While 10 days should not be expected for a Nook Color (that is what a Nook Classic gets), 10 hours is probably possible. I don't know how much your Nook was charged before you started using it, etc., but you might have a bad unit. However, if you have WiFi on but no WiFi available, if your screen brightness is set to maximum, etc., there might be a reasonable explanation. I don't know what the normal range could be, but I only charge mine every several days.
Second, both the Nook Color charger and the Nook Color charging USB cable are special. Best Buy might have real replacements, but it sounds like you may have gotten a Nook Classic charger, which is more of a standard USB charger. This sort of charger does seem to work, though very SLOWLY, and only if the Nook Color is off or asleep.

The Geek Squad assured me however that this was the replacement cord to use. I told him the device didn't hold a charge for long and he told me that I should try to turn off wi-fi while reading.
Sounds like Best Buy sold you the wrong cord. The NOOK cord is white, the NOOKColor cord is black
The regular Nook charger will not work. The following paragraph was cut and pasted from PCmag.com.
"Although the Nook Color looks like it has a standard micro USB port, it will only charge with the Nook Color AC adapter. I tried both 5V and 10V adapters, with no luck. Nor can you charge the device by connecting it to a PC. Turns out the cable that comes with the Nook Color has a few extra pins in it, to enable faster charging. The custom connector supports 2000mAh charging, whereas most mobile electronics use 500mAh chargers."
I returned my Nook Color for a refund. I had purchased a NewTrent universal battery with a USB interface to extend usage due to the relatively short battery life. I get stuck in airports quite often and hate being tethered to a wall outlet ( if I am lucky!). Alas, the B&N engineers deliberately designed this toy to be incompatible with any aftermarket chargers or extenders. No wonder the technical department never responded to my query after I pre-ordered on the first day of availability. I understand the tradeoffs of weight, heat, etc when designing for batteries but I am incensed they eliminated all options from consumers to extend battery life yet retain portability. Shame, shame, shame.
