Great value for Pre-Charged Batteries - with some caveats
on October 24, 2009
The Kodak KAARPC NiMH 2100 mAh belongs to the latest generation of low-self-discharge NiMH cells. It may not be as well-known as other brands (SANYO eneloop, Rayovac Hybrid, Duracell Pre Charged) but it is just as good according to my own testing:
1. The battery capacity is specified as 2100mAh. But the average capacity I have measured (using my La Crosse BC-900) is actually closer to 2200mAh!
2. After three months in storage, the capacity lost is only around 10%. This is even better than the results I got from eneloop and Hybrid (both close to 15%). Note that the difference could be due to measurement error and different ambient temperature, since those cells were not tested during the same period.
I have used more than a dozen of those Kodak Pre-Charged AA cells in digital camera (Canon S5), external flash (Canon 420EX), plus various toys and gadgets with great satisfaction. This Kodak 4-pack is an excellent buy, especially since it can be found at lower prices than other brands of pre-charged cells. If you are also looking for a fast and compact travel charger, then I highly recommend buying it with the KODAK K6200.
However, there are a few caveats when buying or using those Kodak Pre-Charged cells:
1. Those cells are slightly fatter than ordinary alkaline cells. Most appliances have no problem accepting them, except for my Microsoft wireless keyboard which has a very tight battery compartment. In this particular case, I have to use Hybrid AA cells since they are slimmer than others.
2. One great irony is that: you can use these Kodak rechargeable batteries in most digital cameras that accept AA cells, except for KODAK cameras. The reason, as least according to my own undersatnding, is that Kodak want you to buy their Kodak KAA2HR-PC battery pack instead. There is a micro-switch inside each Kodak camera battery compartment, which gets depressed when the Kodak battery pack is inserted. That's how the camera knows rechargeable NiMH cells are being used. If the switch is not depressed, the camera assumes alkaline cells are used. Therefore it will trip 'low-battery' signal prematurely, because the nominal voltage of NiMH cell is lower (1.25V, compared to 1.5V for a freash alkaline cell).
