Many different battery brands include AAA batteries some examples of AAA battery brands include two of the biggest battery brands, Energizer and Duracell.
Battery brand isn't that important. The time to charge is mainly dependent on the capacity of the battery and the capacity of the charger. Any reasonable modern charger should sense when the battery is full and cut power when it's done. It can take some hours for a full charge.
Look for a plus symbol on your battery. The plus sign, or +, indicates the positive terminal. On AA, AAA, C, and D batteries, the positive end should be slightly raised.

It depends how long you use it. The more songs you play the more battery you use up as you might know. It probably has longer life than normal batteries though. Hope this helped. :)
This depends on the working conditions.
Duracell!!!

AAA is the size of the battery, there are many types and makes of AAA battery and the shelf life for each is different.
That depends entirely on the rating of the charger !
