Here we list details about the battery inside the JBL Charge 2 Plus speaker, including capacity, dimensions, mAh value and play time.
Furthermore, the mAh or milliamp-hour value tells us how long the battery will supply sufficient power based on amount of current drawn from it. Explicitly, the mAh figure tells us how many amps the battery will provide for an hour.
Plus, using a bit of math you can also gather from this number how long the battery will last for any amount of current drawn from it. The calculations go like this. If you double the amount of current, you halve the 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 unit very loud lessens the speaker 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) yours. Finally, this is why playing softly lengthens the time it can run per recharge.
