Battery Notes

For logistic reasons the µGame 10 is shipped without a battery. The user has to attach and solder the battery themselves (before attaching the display). Pretty much any lithium battery will work with the built-in battery charger, but as the charger works at 400mA, it is important that the battery can be charged with that current. Usually this means that the battery has to be at least 400mAh in size. The Nokia BL-5B battery is recommended, as it has the right size and shape, stores around 800mAh, and is contained in a safe package that fits well on the back of the device. Any other phone battery of similar size should also be suitable.

Note that to charge the battery, the power switch has to be on while the device is connected to the USB port.
