Also, the mAh or milliamp-hour value tells us how long the battery will supply enough juice based on amount of current drawn from it.  Explicitly, the mAh figure tells us how many amps the battery will provide for one (1) hour.

Plus, using a bit of math you can also gather from this number how long the battery will last before dying, for any amount of current drawn from it.  E.g. If you double the amount of current, you halve the remaining play time.  E.g. If you draw two (2) amps, a one amp-hour battery will last for thirty (30) minutes or 1/2 hour.  Thus, this is why playing the speaker very loud lessens the Boombox 2 play time per charge. Also, if you cut the current by half, then you double the play time per charge. E.g. If you draw just half (1/2) an amp, our hypothetical one amp-hour battery will last for double the time, or two (2) hours.  Finally, this is why playing the speaker softly lengthens the time it can run per recharge.
