How To Charge A Scooter Battery Without A Charger

Yes, got it, you have a question about your scooter battery, right? Ok, we’re ready to answer any question about your scooter battery or charger. We want to discuss in the article how to charge a scooter battery without a charger.  Scooter is one of the astounding developments of the innovation which makes moving simple, eco-friendly, and reasonable type of transportation.

Power of the scooter is electricity. They are furnished with a battery which should be charged before utilizing. You will get a charger with a scooter to charge the battery. It turns out to be difficult to charge the battery of the scooter when you lose the charger or harm it. Please read the content carefully and follow the instructions.

Without A Charger: Is It Possible?

The battery is a vital part of the scooter. We often charge the battery with the charger. However, we can charge it without a charger if you have a kids scooter or a razor scooter.

General Steps

You need to know how to charge scooter battery at home or how it happens without a charger. There are some general steps you can follow.

1. Remove The Battery

You have to expel the battery from the scooter before you continue with the recharging techniques depicted beneath. This is significant in light of the fact that the elective strategies produce a ton of warmth. If you leave the battery inside its fenced-in area, the warmth has no place to go and your battery is probably going to overheat.

As recently indicated, the accompanying advances may be fairly unique relying upon your scooter. However, you can generally check the scooter’s manual to get a detailed guide on the most proficient method to get the battery out.

2. Removing Screws

By and large, a couple of screws and a plate hold the battery inside your scooter. Expel the screws and the plate to achieve the battery.

3. Disconnect

There are two wires that interface the battery terminals to the scooter motor. The cathodes are generally associated through slide-in trapdoors or clasps. Cautiously expel the connectors to keep away from any harm. Another clasp or pole may hold your battery, so you have to remove it also.

4. Position

Spot the battery on a dry level surface before associating it to an elective power source.

Charge With A Portable Car Jumper

Utilizing a vehicle jumper is generally one of the speediest techniques to energize batteries. These jumpers have a huge versatile battery implicit, something significant enough to kick off a vehicle’s battery.

1. Connect

Connect the jumper cables to the battery’s terminals. The red cable goes to the positive anode and the black cable connects to the negative terminal. Double check the associations with guarantee everything fits appropriately.

2. Turn On

When the jumper is on, the current begin streaming into the scooter battery and leave it to charge for 20 minutes. The charging time may rely upon the battery type; you’ll need to improvise. When the battery gets hot, it’s a most likely path over half charged. Leaving the battery overheated for a really long time will abbreviate its life.

3. Disconnect

Turn it off when it’s suitable. Disconnect the black cable, at that point the red cable

Charge With A Variable Power Supply

 A variable power supply is a helpful contraption accessible at any hardware shop. The yield voltage is customizable and it recharges the scooter battery while constraining the progression of electrical flow. A similar standard about overheating as the plot above applies.

1. Connecting The Variable Power Supply

At this point, you can figure that the black cable associated with the negative cathode and the red one interfaces with the positive anode.

2. Voltage

For recharging, the voltage ordinarily should be set to 4.20V/cell. Obviously, there’s no real way to tell what number of cells are in your scooter, so you’ll need to speculate or possibly contact the manufacturer.

3. Current

An excess of current may sear the battery so you’ll need to go preservationist here. Look into the limit of your battery and set the current to 20%. For instance, if your battery is appraised at 9Ah, set the yield current of the power supply to 1.8A.

4. Waiting For The Charge

The provided current will drop as your battery fill up. When the present tumbles to about 3% of the bike battery’s appraised limit (Ah), it’s an ideal opportunity to discharge the variable power supply and set the battery back in your scooter.

Charging The Several Batteries

There are 3 several batteries of the scooter battery. You should know the details of the charging procedure. In the part,  we discuss how to charge scooter battery.

1. Lead Acid Batteries

The lead corrosive batteries are one of the most established kinds of batteries utilized in numerous viewpoints for over 140 years. They are additionally mainstream for higher strength and tolerant to overcharge. They are utilized in many scooters these days because of their low cost and different focal points.

If the scooter is outfitted with a lead corrosive battery, at that point the main thing you should do is ascertain the precise voltage relying upon the quantity of the cells. At that point contingent upon the voltage, you can charge the battery utilizing the variable charger. The variable charger can be found in any neighborhood or online electronic shops.

Keep in mind that, charging the lead-corrosive cells utilizing the variable charger is a dangerous alternative. The charging ought to be checked appropriately. Check the temperature, voltage, and current stream for a few times entire charging. Separate the charger from the battery when the battery is full.

2. NiCd& NiMH Battery

NiCd and NiMH are two unique kinds of battery, however, they work similarly. The two kinds of battery utilize synthetic response to store power to control your scooter. They are well known for better vitality thickness and power putting away capacity.

The NiCd and NiMH Scooter Battery are somewhat harder to accuse looked at of different batteries. Particularly, it’s trying to distinguish full-charge in these batteries. The best way to distinguish the full charge is the temperature rise. On the off chance that you see a 0.3 – 1C temperature rise, at that point, you need to accept it as a sign of a full battery.

It takes around 3 hours to charge a void 2Ah NiMH battery at 750-1000mA. Regarding the above depiction, you can charge the battery utilizing a variable power source as like as the lead cell.

3. Lithium-Ion Batteries

Lithium-ion cells are the most widely recognized kind of batteries accessible at present. They are utilized in the greater part of the cutting edge electrical hardware. Lithium-ion batteries are exceedingly adaptable, store much power, don’t create extreme warmth, and accessible at an affordable price everywhere throughout the world.

You can utilize a power supply to charge the lithium-ion batteries. You should set the edge as per the full charge voltage, which is normally around 4.20V/cell. Ensure that these cells that are associated in an arrangement don’t surpass the voltage.

You can accept it as a sign of full charge when the cells achieve 4.20v/cell. The present drops in 3 per cent of the evaluated current. Detach the charger when you discover the sign of full charge. Ensure that you don’t cross the limit of the voltage.


You don’t have to face much traffic jam on the road if you’re utilizing a scooter. Another fascinating thing is it doesn’t cost you a lot of cash when if you compare with the other type of transportation. It’s important to know a scooter owner how to charge a scooter battery without a charger. This article will help you a lot.
