Another Useful Tip
Another of the extremely useful tips from All-Battery [see margin for link] is included in quotes below...
"Battery capacity ratings are meaningless when used to compare different types of batteries or to compare the capacity of batteries powering different types of devices.
This means that you may not be able to predict how long your electronic device will run just by looking at the capacity rating of a battery. For example AA alkaline batteries typically have a capacity rating of over 2,500 mAh and AA NiMH batteries have rated capacities of only 1,200 to 2,600 mAh. But when it comes to actually powering an electronic device like a digital camera, the NiMH batteries will often run the device for three or four times as long.
Unfortunately, even comparing the capacity ratings of similar types of batteries won’t always work because different manufacturers often measure battery capacity in slightly different ways."
