That's pretty good. Have you compared the two, normalizing for
capacity? PrimeCell claims to use higher capacity cells than
stock. If the PrimeCell rebuild gives you 10% longer run time,
that may tip the equation more in their favor. For some
combinations (NiCd to NiMh conversion) they claim up to 50%
longer run time. That's pretty remarkable.

That's the part that got my attention. Time is money.
