AA batteries for HT ham radios (particularly Baofengs)
For those of you who use AA battery packs as backup power supplies for your HT radios, particularly Baofengs, what kinds of batteries do you use? Alkaline? Disposable lithium? Rechargeable? How long do they batteries tend to last when powering the radio? (I realize this is dependent on the usage, but some idea would be helpful.) How many sets of batteries do you carry for your radio?
