Note: Battery characteristic varies depending on factors such as ambient
temperature, charging method, load current, aging, etc.
For example, at low temperature the chemicals of the battery are more
inactive, thus decreases the output power.
The battery gauge should only be used as a reference. Please do not
expect it to show the exact amount of the power remaining.
There is no memory effect on Lithium Ion battery cells. However,
discharge the battery to nearly empty every month will help calibrate the
internal gauge.
