) —
A battery composed of
lithium, a light metal with high electrochemical potential. Lithium
batteries are light and store high amounts of electrical energy. Because of
this, lithium-polymer batteries are ideal for your portable device. Lithium-
polymer batteries do not use poisonous metals, such as lead, mercury, or
cadmium, and have no "memory effect" problems (caused by not being
fully discharged before a new recharge, and remembering a shorter
battery cycle). However, they are more expensive than conventional
nickel-cadmium (NiCad) and nickel metalhydride (NiMH) batteries.

(MB) —
About 1 million bytes. Bytes, megabytes, and
gigabytes are measures of how much data a storage device can hold.
For example, a 3-minute MP3 encoded at standard bitrates is
approximately 3 MB in size.
MP3 —
A member of the MPEG compression family, MP3 is a
commonly used compressed digital-audio format. MP3 encoding
transforms digital audio files (like WAV) to provide reasonable audio
quality in relatively small file sizes.
