Replacing your Power Mobility Batteries is a great way to breathe new life and the extend the range of your Mobility Scooter or Chair.

Mobility Battery Replacement, How To


If you are buying a new battery you will need to follow the steps below (and any in your owners manual) to help find the right one for your mobility scooter or chair.  You can purchase new batteries from the scooter manufacturer, but be prepared to pay significantly more.  HME Medical Shop Offers Universal Mobility Batteries along with Batteries sourced directly from the Mobility Manufactures at lower costs.You may purchase the same battery size and strength as you have been using.  You can also upgrade to a longer lasting battery to extend the distance your scooter or chair can travel.  That's right, you can get a new, extended range battery.  The Power (Volts) will stay the same, though the increased AMPs to extend your mobility devices range.  Read below for more information. . .


3 Key Points When Replacing Your Mobility Battery

One:  Amps and Volts (ah and V) - How Strong and how Far will it Take Me?

Most Scooters and Chairs use a 24 Volt Motor - this will require two 12 volt mobility batteries.   Be sure to reference your owners manual or current batteries to verify the battery types.  The existing batteries will have the voltage and amps right on the side or top of the battery cover.  Just like we discussed in the previous section, you need to keep the same Voltage (V), but you can get one with higher Amps (ah).  Just be mindful of the Battery's physical size.

Two:  Battery Size - Will it fit in your Scooter?

If the numbers on the side of the battery (i.e. UB1220, UB1280, etc) match what you are purchasing, then it will fit 99% of the time.  See how big your current battery is to make sure the one you are purchasing matches the old battery size.    If you are upgrading be sure to measure the battery pack or case, some do not leave room for upgraded  batteries.  You can purchase an upgraded case by itself, usually for around $100-$150 -  feel free to chat with us about finding the right case for you.  Again, when in doubt, measure!

Three:  Terminal Type - Will It Fit My System?

Without the correct terminal type, the battery will not connect to your scooter or chair correctly.  The Two most common are F1 and F2 Battery Terminals.  Simply put, the F1 is smaller than the F2.  The F1 is 1/8" (4.75 mm) and the F2 is 1/4" (6.35 mm). The F1 is the most common for Mobility Batteries, though be sure to measure or consult your owners manual to be sure.  Below is a side by side comparison.  Again, if in doubt, simply measure your current batteries.

How To change A Battery

We always recommend the instructions included with your item.  If these are not available you can call the manufacturer for a new set or for a phone consult.  Overall it is similar to changing a car battery and pretty straight forward.  To disconnect, Be sure to use the right tools and always disconnect the Red (Positive) connection before disconnecting the Black (Negative).  And never let the connections or wires come into contact with each other.  We included an example video of a Drive Medical Scooter having it's batteries replaced, though your specific scooter or chair may differ.
