What does "recondition the battery" mean?
The battery circuitry tracks charge level and usage patterns to estimate how much time you have left. If you go for a while without draning the battery all the way, the estimates can become inaccurate. Therefore it is recommended that you deep-cycle the battery about once a month, draining it all the way then charging it all the way up. This reminds the circuitry of the actual capacity of the battery, and this is what is called reconditioning.
Don't be tempted to drain the battery every time. While deep-cycling was necessary with NiCads and NiMH batteries, it's bad for Li-ion batteries.
