Hi. I've got an MP4 player watch which I can charge from either a wall outlet, or from the computer. Can you tell me what sort of battery do they have, how long should it take to charge and is it possible to "overcharge" one?
Thanks
John |

Most MP4 player wrist watches use Lithium rechargeable batteries, 2.7 to 3.3 volts. It takes about 6 hours to fully charge a completely drained battery.
Your MP4 watch's lithium battery comes with built-in circuitry that protects it from overheating, so leaving the MP4 phone to charge overnight or over a couple of days will not damage it.
Overheating can reduce the lifespan of your lithium battery....so, do not leave your MP4 player watch exposed to the sun, next to a heater or radiator, because that will surely reduce the battery life.
