2. The accuracy of the percentage of battery charge remaining depends on operating conditions

and the present loading of the UPS. The accuracy will be much more precise at the lower
percentages than it is at the higher percentages (where the performance curve flattens and a
perfectly correct interpolation is more difficult - in the 92-100% range).
