Even the best RV batteries drain out of charge, scooter batteries are nothing compared to that. Because your daily ride takes more juice every day. 

We know that it can be a huge deal if you stumble upon an empty battery to work one day. You might not even have a charger for the battery at the moment.

So, how to charge a scooter battery without a charger? Well, you’re in luck today because we are here to offer you a hand.

Without further delay, let’s get you started-

Why You Need a Battery for Your Scooter?

Well, it’s very normal for you to question the need for a battery in a scooter as it’s already running on fuel. 

You see, the scooters won’t even start without a battery. The battery gives your engine the power to start up and get running. It is the most crucial part of your scooter.

Your scooter’s battery should be charged enough to get your scooter started. And if it drains out of charge, they often come with a designated charger.

However, if you’re not provided with a charger, you can still recharge your battery. And that’s why we’re here today.

How to Charge a Scooter Battery without a Charger

Yes, you can charge your scooter battery manually. All you need is a simple power supply that can charge your battery. 

You should be able to adjust the voltage because overpowering your battery is not an option at all for you.

As charging your scooter battery with a power supply comes with a risk, you can’t leave your battery unattended. 

You see, the battery will keep on charging even when it’s full. And in that case, there are possible chances that it can turn into overheating, damaging the internal cells, or maybe an explosion. 

However, there are different kinds of batteries for your scooter. Let’s see what you have to do in order to charge each one-

Charge Lead Acid Scooter Batteries

We’ll start with the lead-acid batteries first. At the very beginning, if you have a lead-acid battery, you need to check how many cells does the battery has. 

Step 1: Connect to a Power Supply

If you’ve checked the cell number of the battery, now you know how much voltage you need for it. 

You need a power supply now that you can adjust to the preference of your battery. Connect your battery to the power supply. 

Step 2: Set Desired Current and Voltage

Now that your battery is connected to the power supply, you need to make sure that your battery is getting the proper juice it needs. 

And for that, you need to set the right voltage and current that your battery needs. If you have a usual lead-acid battery, the electricity should be in the middle of 10% and 30% of your rated capacity. 

For instance, a usual 10Ah battery which is at 30% charges at about 3 Amps, and the percentage can be beneath that margin. 

Step 3: Monitor the Battery

As mentioned before, this is a risky operation and you can’t leave the battery unattended while charging. 

There are a few things like battery temperature, voltage and current flow that you need to keep eyes on. Keep on monitoring them while the charging is in process.

Step 4: Disconnect When It’s Time

Once you notice that the current drop to 3% of the rated, it’s time for you to disconnect the charger. Make sure that the battery is full.

Charging Lithium-ion Scooter Battery

A lithium-ion battery is considered as an alternative to the lead-acid battery. You can charge it the same way, with the help of a power supply. But you might need little extra measures.

Charging NiCd & NiMH Scooter Battery

Now we’re going to talk about something a bit different, nickel-based batteries. 

The charging process of this battery without a charger is a bit different than the others and we’re going to break this up for you step by step.

Step 1: Attach a Power Supply

We know that we said these batteries are different than the other but still the major steps are similar. We do need a power supply to connect with this battery to charge it up just like the others. 

Also, just like the other batteries, this one should also have a power supply that you can adjust. 

Step 2: Set the Current and Voltage

As you can adjust the current and voltage of the battery, you need to be very precise on what you do.

Adjust the right amount of current and voltage you need for your battery to charge up. 

Step 3: Monitor the Battery

Now here’s the thing.

The biggest challenge with nickel-based batteries is that you’ll be able to detect full charge but it’s going to be in voltage. Yes, the voltage that’ll possibly vary when you apply charge current. 

Also, you need to make sure that the temperature rise is from 0.3 to 1C and you get the quick charge. Any normal empty 2Ah nickel-based battery will take 3 hours to charge at 750-1000mA.

Step 4: Disconnect When It’s Time

The key to charging this battery is that you have to be very precise about all the steps that you’re taking. Or else, it might become a mess for you. So, disconnect the battery right away when it’s fully charged. 

Conclusion

So, that’s all we had on how to charge a scooter battery without a charger for you today. Hopefully, we’ll be able to come in handy for the whole process. 

However, there are a few words that we’d like to share with you. You see, battery drain is quite a familiar issue with a daily driven or idle sitting scooter.

You should just charge it once in a while if you don’t want to face an empty battery one morning. 

Moreover, you should be very cautious when you’re dealing with electricity. We don’t want you to end up in a hospital today.

So, best luck on filling in some juice for your battery today.
