I heartily agree with the earlier reviews, this IS a very impressive battery, and you have to shop for good prices. I have found excellent prices on this battery here on Amazon - simply by looking around.
A bit of caution: Size C Low Self Discharge batteries are often just a AA LSD inserted into a C shell. This is NOT the case with the AccuEvolution. The AccuEvolution C is a real battery through and through - with a capacity of 4,500 mAHs (over twice as much as a 2,200 mAH re-wrap). This is why the AccuEvolution is noticeably heavy.
Real cost: I recently came across an interesting article online that compares the actual cost per amp hour of a typical alkaline battery vs this battery. A name brand size C alkaline on sale for $0.94 is shown to cost $46.81 for 100 mill amp hours, while an AccuEvolution size C priced at $9.98 costs just $0.19 (including cost of electricity and charger) per 100 milli amp hours. This is a difference of slightly over 300%.

These batteries are absolutely amazing. Low self discharge, high capacity, and capable of super high currents. They might seem pricey, but if you have high drain devices that use C-cells, then you NEED these batteries. I make custom high-output LED flashlights and these are a perfect, safe, high-output power solution that provides always ready, high output and long runtime in four of my favorite 3*C-cell torches.
If your application fits ordinary Alkaline C-cells snugly, then these might not fit as they are a hair wider. I have also found that the ones branded AccuPower Evolution are slightly fatter than the newer ones branded AccuEvolution.

I bought a set of these for one of those electric canine toenail grinders, and I can say they work great! They hold a charge for a looong time, and source very good power when I use them. An electric motor is a very good test of batteries, as it is a very high current drain device. I charge them once, and leave it in the drawer until I want to use it, which is a long time in between, and when I finally go for it, it still has a good charge, and provides plenty of power...
