After reading a number of on-line reviews, I was all set to send a 1.3 Ah
12V DeWalt drill battery pack off to MTO:

I gathered your info into a spreadsheet.
This is an eye-opener with a 2:1 spread in dollars per watt hour.
The Primecell NiMh at U$0.39 per watt hour is the cheapest and the
MTO NiMh at U$0.81 per watt hour appears to be the most expensive.

I can see that the Primecell 3.3 AH NiMh (at U$0.61 per WHr) may be
the value leader, considering its high capacity and '$/WHr' price
near the middle of the range.

The MTO 'Regular Duty' 2.1 AH NiCd battery loses the competition
because it is near the top of the cost range (at U$0.09 more per WHr
than the 3.3 AH Primecell NiMh).
