Batteries and charging

The range of your vehicle

Most manufacturers of mobility products state the range of their vehicles either in the sales literature or within the Owners Manual.

The range stated sometimes differs from manufacturer to manufacturer even though the battery size is the same. Sunrise Medical measure the range of their vehicles in a consistent and uniform manner, but variances still occur due to motor efficiencies and overall product load weight.

The range figures are calculated to I.S.O. Standard 7178, Part 4: Scoota Energy Consumption Theoretical Range.

This test is carried out in controlled conditions with new, fully charged batteries, on a level test surface and a user weight of 75kg.The range figures stated should be seen as a theoretical maximum and could be reduced if any single, or combination, of the following circumstances occur:

1.User weight heavier than 75kg.

2.Batteries whose age and condition are less than perfect.

3.The terrain is difficult e.g. very hilly, sloping, muddy ground, gravel, grass, snow and ice.

4.The vehicle climbs kerbs regularly.

5.The ambient temperature is very hot or very cold.

6.Incorrect tyre pressures in one or more tyres.

7.Lots of start/stop driving.

8.Also thick pile carpets within the home can affect range.

All this technical information may seem complicated and a little daunting, but please remember, that the battery sizes available on your Sterling Elite XS should give sufficient range to cope with the majority of customer’s lifestyles.
