There's 15 cells in that pack. Let's figure a rough price of $3 a
cell (I dont think i've ever seen them at that price, btw). You're
already at $45 for 1 battery and you havent even figured in the cost
of labor.

I dropped my 12V DeWalt batt off at a rebuilder last week.
This is the standard OEM battery, not the XR.

"10 cells @ 3.50" = $ 35.00 CDN/24.00 US

Supposed to p/u Tues.
