TESTING THE BATTERY
If your board suddenly quits working, its not likely the battery pack. Worn out or defective batteries usually result in range reduction. As your batteries age, your range will gradually decrease, until the point is reached the range is unacceptable, and they will need to be replaced. An immediate and severe drop in range can be attributed to a defective battery charger, or a defective battery (the battery pack is built with four separate 12 volt batteries). If the powerboard has not been used for some time, and the batteries have not been kept charged, it is very possible that the battery is the issue.
