Depending on your device, you are going to look for different battery features. Click on the links below to sort the comparison table:
You are looking here for a low self discharge battery such a disposable alkaline or lithium battery.
Devices with a large battery turnover (heavily used or energy hungry):
You are looking for rechargeable batteries with the best value regarding capacity (and number of charge cycles).
Power hungry/high drain devices:
You will want a battery with a very low internal resistance (to let the current flow), measured in miliOhms. Rechargeable NiMh usually perform well here.
