If you are trying to find out if the battery (or batteries) for your mobility scooter needs to be replaced, then you’ve found the right place. In this FAQ page, we will go over the different types of scenarios you may encounter when trying to troubleshoot your mobility scooter and ultimately find out if your batteries are bad.

First, you must find out what type of battery you have and how many batteries the scooter uses. If the scooter is a normal travel-size scooter, it likely has a pair of 12-volt Sealed Lead Acid batteries inside of a battery case as shown below.

If this is the case, you will want to check each battery to see what the voltage is while under load and while not under load. When the term “under load” is used, that simply means while the scooter is in motion, or when the motor is activated and physically moving the scooter. When a mobility scooter’s batteries have gone bad, typically, the voltage of the scooter will drop below 22 volts which is a sign that they are going bad. The lower the voltage gets, the worse the batteries are. The normal operating range for voltage under load is around.
