Why is my Invacare XPO100 Oxygen Equipment battery gauge dark when charging?

If the battery gauge on your XPO unit is dark while charging, first, try another power outlet and check all connections to the charger and the unit to ensure they are secure. The internal battery may also be outside the allowed temperature range for charging. Allow the unit to cool down to less than 95ºF, or warm up to 50ºF.
