Connect the Jumper to the Battery

The first thing you need to do is connect your jumper to the battery. As you probably know, which wire connects to which. Make sure to connect the wires accordingly which is the black wire to the negative and the red wire to the positive.

You should check for any leaks and brakes in the battery. It might be dangerous for you to use a car jumper on such batteries.

Turning the Jumper on

After the wires are connected to the port, it’s time to start the jumper. Switch it on, and that should charge up your scooter battery.

It will take anywhere from 20 minutes or more to charge it fully. Make sure you don’t disconnect it while you are charging. It requires caution as it has a risk of damaging the battery in the long term.

Disconnecting the Jumper

When the battery is full, it’s time to disconnect the jumper. You have to be very careful to avoid getting shocked while doing it.

First of all, you need to unplug the negative port from the car jumper. Then it’s much safer to unplug the positive port. After you are done with all these, your electric scooter battery is fully charged and ready to go.

Using a Universal Power Adapter To Charge The Scooter Battery

Those are devices that you can find at any hardware store. It’s great if you are looking for how to charge a scooter battery without a charger. Besides, a universal power adapter is a pretty handy device that you might need for a lot of things.

But like every other method, it involves some risk. To charge your battery using a universal power adapter safely, you need to follow the rules given below.

Connecting the Variable Power Supply

Start by connecting the connectors. You probably know that the red one connects to the positive, and the black one connects to the negative electrode. Place them in the spot properly.

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 4.30/cell would be enough. It’s preferred for you to set it right in this range.

Setting the Current

You also need to be careful about the current. Too much of it will overheat the battery, and you don’t want this to happen.

It’s recommended to set the current at 20% of the capacity of your scooter battery.

Waiting for Charge

Now that you are done with the steps shown above, it’s time to wait for a bit. The battery will be charged as the supplied current will drop. When the current falls at 3% or below, it’s time to disconnect it and put the battery back in 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

First of all, you need to measure the voltage before you even start to charge a lead-acid battery. The number of cells typically determines that in a battery.

After you get the correct calculation, you just need to use an adjustable power supply to charge it up. You’ll need to set the voltage and the current limits in which you want to charge the battery.

For instance, the average lead-acid has 2 volts per cell. That means, for a 12-volt battery of that type, you’ll need to set the voltage to 12 volts.

Also, you must select the charging current accordingly with the size of the battery. It’s better to adjust the current between 10-30 percent of the rated capacity for an average-sized lead-acid battery.

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 an 8A current charge normally.

If you take a look at the battery charger info, you’ll see that it’s risky to use a variable power supply 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 as the battery is charging. Make sure to only charge it in a well-ventilated room with a normal temperature. You should always remove the charger when the battery is charged.

Also, it’s worth mentioning that you should keep the voltage level slightly high. That keeps you from damaging the battery in the long term.

You might find methods like charging a deep cycle battery from cigarette lighter socket. But it’s better not to use those methods to ensure the safety of your scooter battery. Also, it doesn’t matter even if you use the best way to charge trolling motor batteries; the battery drain is a common issue.

Charging a Lithium-Ion Battery

It’s the most used battery in the electric scooters nowadays. If you know how to charge a motorcycle battery without a charger, then you know you can charge the battery using a power supply. But the measures are not as simple as the lead-acid batteries.

It’s recommended to ensure that the full charge is mostly 4.20 volts per cell. Now, you just have to set the voltage and the current flow by that. Make sure that you inspect the monitor thoroughly and see if the cells connected are exceeding the voltage flow.

Ultimate guide to electric scooters

Again, just like the lead-acid battery, you need to disconnect the charger when it’s fully charged. The charge will reach 4.20 volts per cell voltage, and the current will drop at 3 percent. That’s when you know that you need to disconnect the charger.

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, and 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’s important to get a good quality battery 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 general.

However, you should use a voltmeter on the NiCd and NiMH batteries. They should have a reading of 13.7-13.9 volts. It’s a preferable voltage. But anything less than a 12 bolt tells that it’s a depleted battery.
