So, How to charge electric scooter without charger?
As people have a common misconception that scooter batteries can only be charged with the charger that’s provided by the manufacturer, that’s a myth.
But surely, you are going to need some equipment for this. You’ll be able to make a portable home charger yourself. This gadget provides an adjustable voltage current to charge your scooter battery with ease.
Let’s go over the steps of making one.
A Step By Step Guide on How to Charge a Scooter Battery without a Charger – Build Your own Battery Charger Easily
It doesn’t matter if the scooter is from stores or BabyGearsLab, you’ll need a charger to charge the battery. Making your scooter battery charger isn’t as complicated as you might think.
But as you can probably guess, alternative method runs a risk of damaging the battery in the long run. To avoid that, make sure to go through the following steps.
In order to make a portable charger, you will need a few pieces of equipment.
You are going to need some de-ionized water or electrolyte. You can easily find that on any hardware store. Then you’ll need some electric cables for the connections.
Also, you’d have to purchase a voltmeter and a hydrometer to see what’s going on and inspect the procedure properly.
Gloves and goggles are the most important thing that you have to get to ensure maximum safety. After you have everything, you’ll need a cool and dry place to work on.
To start the process, first, wear safety gears, which is the most important thing to do in the beginning. Working with batteries is not safe. Thus, it’s important to have good protection.
Now, remove the scooter’s battery and put it somewhere dry. Remove the chamber caps as well.
All you have to do now is full up the chambers with de-ionized water. Make sure to pour it slowly. You don’t want to spill the water everywhere. Once you are done, put the cables accordingly to the negative and positive terminals and turn the power on.
Now, you must check before proceeding any further. In this case, use a voltmeter to see if the battery is fully charged or not. If it’s done, you can power it off and put the chamber caps back on.
That will do the job perfectly while also charging your battery.

Setting the Voltage
This part is very important for the safety of your battery. You should look at the owner’s manual for getting an idea of how much voltage is supported in the scooter battery. Contacting the manufacturers will be a great idea in that case.
But typically, setting the voltage to 4.30/cell would be enough.
Setting the Current
You need to be extra cautious while setting the current up. Too much will overheat the battery, and you don’t want this to happen. It is recommended that you set the current at 20% of your battery’s capacity.
Waiting for Charge
Now, that you are done with the steps described above, it’s time to wait. When the current drops to 3% or below, it’s time to disconnect it and put the battery back inside the scooter.

Charging the Different type Of Batteries
Unlike any regular scooter such as the Razor Pro RDS Dirt Scooter – Red, having batteries allow you to ride your scooter without any effort. There are several types of batteries that are getting common for electric scooters.
When it comes to charging batteries, different batteries require different methods to charge up effectively while ensuring safety. Let’s go over them down below.
Lead Acid Scooter Batteries
Before you begin the procedure, you must first measure the voltage.
After you get the correct calculation, you just need to use an adjustable power supply to charge it up. Also, you’ll need to set the voltage and the current as per the calculation.
For instance, the average lead-acid has 2 volts per cell, which means, for a 12-volt battery, you’ll need to set the voltage to 12 volts.
Also, you must set the current according to the size of the battery. For an average-sized lead-acid battery, it is recommended to regulate the current between 10 and 30 percent of the rated capacity.
As an example, a battery that’s 10Ah charges at around 3-Amps at 30 percent capacity. That can be a bit higher or lower. Thus, a battery with 80Amps will require 8A current normally.
When you take a look at the info written over a variable power supply, you’ll notice that it’s risky to use to charge a battery. You must stay present at the moment to avoid any risk. If you are asking, “Is it bad to use your phone while charging?”, the answer would be a yes.
You should stay alert and monitor the temperature, voltage, and current flow while the battery is charging. Make sure to charge it in a well-ventilated room with a normal temperature.
Also, it’s worth mentioning that you should keep the voltage level slightly high.
Methods such as charging a deep cycle battery from a cigarette lighter socket could also be found. However, you should avoid using this method.

Charging a Lithium-Ion Battery
It is currently the most commonly used battery in electric scooters. However, charging lithium-ion batteries with a power supply is not as simple as charging lead-acid batteries.
The optimal full charge is 4.20 volts per cell on average. Therefore, have to set the voltage accordingly. Make sure that you inspect and monitor thoroughly and see if the cells connected are exceeding the voltage flow.
The charge will reach 4.20 volts per cell voltage, and the current will drop at 3 percent.

Charging NiCd and NiMH Batteries
These batteries require more precautions on your side to charge without a charger. You’ll be able to charge it with an adjustable power supply. But the full-charge detection varies with charge current making it pretty challenging for you.
You should always keep an eye on the estimated level of remaining charge, as the temperature rises. It’ll be wise to calculate the charge time as well. A standard 2Ah NiMH battery takes 3 hours to charge at around 750-1000mA fully.
As you probably know, battery draining can be an issue sometimes. That’s why it is very important to get a good quality charger in the first hand. You might ask, “What’s the difference between a discount store battery charger and an industrially rated unit? It’s better for battery life in the long run.
You must now check the voltage using a voltmeter. The reading should be 13.7-13.9 volts. It is the recommended voltage. But anything less than 12 volt tells that it’s depleted.

Tips for a Better Battery Life of the Scooter
An electric scooter is nothing like a wagon for two plus willow green. You have to take care of its battery. It doesn’t require a lot from your side. You should follow the steps outlined below to extend its lifespan.
1. Avoid Overloading at All Costs
An e-scooter is not a John Deere Bicycle Ride on Toy, Green, 16 Inches that is for certain. That means it can overload sometimes due to some issues.
There is a certain weight capacity that is optimal for your scooter. You should never put excessive weight on your electric scooter. That risks overloading the mechanism of your scooter, which puts pressure on the battery.
So, measure the payload capacity and don’t put too much weight on your scooter to have better battery life.

2. Don’t Change the Speed Often.
Changing the speed every now and then is not always the best thing you can do to improve battery life. It’s even worse if you suddenly accelerate to top speed.
3 .Starting the Scooter Gradually
It’s best to start your scooter slowly. This eliminates the strain on the battery. Thus, making it last longer for an extended period. So, it doesn’t matter if your scooter is top-ranked by Route Vibes, take your time in the acceleration to maintain the longevity of the scooter battery.
4. Maintaining Proper Pressure in Tires
This is another important thing that you need to consider. The proper pressure on the tires make your e-scooter go much smoother. That also takes off load from the battery. Make sure to check if the tires have a decent amount of pressure or not from time to time.
