Как безопасно заменить батареи в мобильно -скутере?
Your scooter is dead, and you need to replace the batteries. Doing it yourself feels risky, and a mistake could be expensive. I will guide you through the process safely.
To safely replace scooter batteries, always turn off the power and remove the key first. Then, disconnect the old batteries (negative first), install the new ones, and connect them positive-to-positive (red) and negative-to-negative (black), ensuring all connections are tight.
This is one of the most common maintenance jobs for any mobility scooter. After a couple of years, the batteries just don't hold a charge like they used to. At my factory, we design our scooters so that this process is as simple as possible. While many people take their scooter to a dealer, this is a job you can definitely do at home. You just need to be careful and follow the steps in the right order. Getting it wrong can be dangerous and costly, but getting it right is simple and will save you money.
What tools and safety steps are required?
You want to start the job, but aren't sure what you need. Using the wrong tools or skipping safety steps can lead to a broken scooter or even an electric shock.
You only need basic tools: a screwdriver and a wrench. The most important safety steps are to turn off all power, remove the key, and wear gloves before you touch anything.
You don't need a professional mechanic's toolbox for this job. We design our vehicles to be serviced with simple hand tools. The priority here is not the complexity of the tools but the safety of the process. A battery stores a lot of energy, and you need to respect that. A small metal tool accidentally touching the wrong two places can create a big spark and a short circuit. That's why following a safe order of operations is so important.
Here are the exact steps I teach all our new technicians:
- Power Down Completely: Turn the scooter's power switch to OFF and, most importantly, remove the key from the ignition. This prevents any chance of the system accidentally turning on while you are working on it.
- Work in a Good Space: Make sure you are in a well-lit and dry area.
- Wear Gloves: Simple work gloves will protect your hands from dirt and grime.
- Take a "Before" Picture: Before you disconnect a single wire, use your phone to take a clear picture of the battery setup. This photo will be your perfect guide for how to connect the new batteries. It's the most helpful trick in the book.
How to identify battery terminals and connections?
All the red and black wires look confusing. Connecting them the wrong way is a major worry, but there's a simple system to follow so you can't get it wrong.
Battery terminals are marked with a plus (+) for positive and a minus (-) for negative. The wires are color-coded: red is for positive, and black is for negative. Simply match the colors.
This is where people get the most nervous, but it's actually very straightforward. The entire industry uses a standard color code to prevent mistakes. Your job is to just match the colors and the symbols. Let's break it down so it's impossible to confuse.
- On the Battery: Look at the top of your batteries. You will see two posts, or terminals. One will have a
+
symbol molded into the plastic case next to it. This is the Positive terminal. It will very often have a red plastic cover on it. The other terminal will have a-
symbol. This is the Negative terminal, and it usually has a black cover. - On the Scooter's Cables: The wires coming from your scooter will follow the same color code. The Red wire must connect to the positive (+) terminal. The Black wire must connect to the negative (-) terminal.
The "Jumper" Cable
You will also see a short cable connecting the two batteries to each other. This is what links the two 12V batteries to create the 24V your scooter needs. Don't worry about this cable. Your "before" picture will show you exactly how it connects. When you put the new batteries in, just connect this jumper cable first, exactly as it was in the photo.
Wire/Terminal Color | Symbol | Connects To |
---|---|---|
Red | + |
Positive Terminal |
Black | - |
Negative Terminal |
How to replace batteries on different scooter models?
You've opened up your scooter, but it doesn't look like the pictures online. Finding the batteries and getting them out seems impossible. It is usually one of two ways.
Batteries are either in a removable pack (common on travel scooters) or under a plastic cover beneath the seat (on larger models). The pack lifts out, while the cover must be unscrewed.
While there are hundreds of scooter models, we manufacturers typically place the batteries in one of two main locations. The method for replacement is slightly different for each, but the principle is the same.
For Travel / Folding Scooters (Removable Pack)
These are designed for portability, so the battery system is made to be taken out easily.
- Locate the Pack: It's usually a single black plastic box sitting on the floorboard of the scooter, often with a handle.
- Lift It Out: There's often a simple latch or it just lifts straight up and out of the scooter.
- Replace as a Unit: For these models, you typically buy a complete, new battery pack. You simply drop the new pack in where the old one was. Sometimes you can open this pack and replace the two smaller batteries inside, but most people replace the whole unit.
For Mid-size and Large Scooters (Under the Seat)
On these more robust models, the batteries are part of the scooter's main frame for stability.
- Remove the Seat: The seat usually just lifts straight up and out of its mounting post.
- Remove the Shroud: You'll see a large plastic cover over the rear section of the scooter. This is the shroud. It may be held in place with a few screws or Velcro tabs. Remove it carefully.
- Access the Batteries: Underneath, you will now clearly see the two 12V batteries, strapped down and connected with wires. This is where you will begin disconnecting them.
What are common mistakes to avoid when installing batteries?
You've got the new batteries ready. A simple slip-up now could destroy your new batteries or the scooter's electronics. Don't let a small mistake become a huge cost.
The single biggest mistake is connecting the batteries backward (reversing polarity). This can instantly burn out the scooter's controller. Always connect red to positive (+) and black to negative (-).
This is the most critical part of the entire job. All the previous steps lead to this moment. When I train service teams for our international importers, I spend more time on this one point than anything else. Connecting a battery with the polarity reversed, even for a split second, sends electricity flowing the wrong way through your scooter's delicate electronic brain.
Here is what happens if you connect the red wire to the negative terminal:
- Instant Electronic Damage: You will likely hear a "pop." That is the sound of your scooter's controller—its most expensive electronic part—burning out. It can also destroy the charger port and other components.
- Blown Fuses: At best, you will blow the main fuse, which is designed to protect against this. But often, the damage is done before the fuse can react.
- Ruined New Batteries: Reversing the polarity can permanently damage the new batteries you just bought, reducing their lifespan or killing them completely.
- Fire Hazard: In the worst-case scenario, this creates a major short circuit that can melt wires and create a serious risk of fire.
Other Common Mistakes:
- Loose Connections: Not tightening the nuts on the terminals can lead to poor performance and sparks. Make them snug.
- Overtightening: Don't use all your strength. Overtightening can crack the plastic and break the battery terminal.
- Forgetting your "Before" Picture: If you get confused, that photo is your best friend.

Replacing scooter batteries is a safe and easy job if you are careful. Power off, take a picture, match the colors, and double-check your work. This simple task can save you money.
