How To Charge Scooter Battery Without The Charger

By Abdul Kader

Scooters are becoming more popular due to their improved battery capacity and range. However, one common issue that scooter riders still face is a dead battery. This can be especially frustrating when you don’t have access to your scooter’s original charger. Fortunately, you can still charge the scooter even if you have lost the original battery.

As you know how to charge scooter battery without the charger, it enhances your riding experience. One way to charge your scooter battery is with a universal charger. These chargers are designed to work with various batteries and has interchangeable connectors to fit into different ports. You can also use a car battery charger or a power bank. However, it’s important to ensure that the voltage and amperage of these chargers match your scooter’s battery specifications.

In this article, we will explore the various ways to charge your scooter battery without the charger. We will discuss the pros and cons of each method and provide step-by-step instructions on how to carry out the charging process safely and efficiently. By the end of the article, you will have a good understanding of charging the scooter battery safely even without the original charger.

Guide For How To Charge Scooter Battery Without The Charger

Scooter batteries need to charge in a specific voltage. The charger that comes with the scooter is optimized to charge the scooter in that voltage. As a result, you can’t use a different charger when your charger is damaged or lost. Here are some of the methods of charging a scooter battery without the charger.

If you didn’t yet buy the scooter but thinking about buying one then consider checking the scooter reviews. It will help you choose a better battery with better battery life and a durable charger.

Scooters come with different types of batteries. So the first thing you require to do is finding out which types of batteries are used in your scooter. Normally there are three types of batteries are used in the scooters which are lead-acid batteries, Lithium-ion batteries, NiCD/NiMH batteries.  Hereinbelow, we will describe how to charge your scooter based on the battery.

Lead-Acid Scooter Batteries

Lead-acid batteries are one of the oldest types of batteries used in many aspects for more than 140 years. They are also popular for higher durability and are tolerant to overcharging. They are used in a lot of scooters nowadays due to their low price and other advantages.

If your scooter is equipped with a lead-acid battery, then the first thing you will need to do is calculate the exact voltage depending on the number of the cells. Then depending on the voltage, you can charge the battery using the variable charger. The variable charger can be found in any local or online electronic shop.

Remember that, charging the lead-acid cells using the variable charger is a risky option. The charging should be monitored properly. Check the temperature, voltage, and current flow for several times whole charging. Disconnect the charger from the battery as soon as the battery is full.

NiCd & NiMH Scooter Battery

NiCd & NiMH are two different types of batteries, but they work in the same way. Both types of batteries use chemical reactions to store electricity to power your scooter. They are popular for better energy density and power storing capability.

The NiCD & NiMH Scooter Battery is a little bit harder to charge compared with the other batteries. Especially, it’s challenging to detect full-charge in these batteries. The only way to detect the full charge is the temperature rise. If you notice a 0.3 – 1C temperature rise, then you have to take it as an indication of a full battery. It takes around 3 hours to charge an empty 2Ah NiMH battery at 750-1000mA. Respecting the above description, you can charge the battery using a variable power source like the lead cell.

Lithium-ion Batteries

Lithium-ion cells are the most common type of batteries available currently. They are used in most of the modern electrical equipment. Lithium-ion batteries are highly flexible, store much power, don’t produce excessive heat, and are available at a low price all over the world. 

You can use a power supply to charge the lithium-ion batteries. You will need to set the threshold according to the full charge voltage, which is commonly around 4.20V/cell. Make sure that these cells that are connected in a series don’t exceed the voltage. You can take it as an indication of full charge when the cells reach 4.20v/cell and the current drops in 3 percent of the rated current. Disconnect the charger as soon as you find the indication of full charge. Make sure that you don’t exceed the voltage limit.

Tips for a Better Battery Life of the Scooter

Scooter’s batteries are designed to provide you around 300 to 400 charging and discharging. That means you can use the batteries for around two to three years. However, if you take proper care of the scooter, then you may use the scooter for much longer. Whether it is a scooter for kids or an adult scooter following the below tips will help you to get better and long-lasting performance from your scooter’s battery. 

  • Always charge the batteries of the scooter. It is a good practice to charge the scooter after every drive. It doesn’t matter whether you have a long distance ride or a short drive, charging after the ride will maximize the lifespan of the scooter.
  • If you are planning to store the scooter, then disconnect the batteries and then store them. Moreover, charge the batteries once in three months to eliminate any chance of oxidation.
  • Excessive hot or cold temperature is destructive for the scooter battery. So avoid storing the scooter in an extremely cold or humid environment. Also, avoid storing the battery in metal or concrete surface as they are conductive and capable of discharging the battery much faster.
  • Never leave your battery partially charged for a couple of hours. It will shorten the battery life within a short time. Charge the batteries fully every time.
  • Make sure the battery is not overcharging. Typically, when you charge the battery with the charger that you get from the manufacturer, you will not need to follow this rule. However, when using the variable charger, you should be careful about the full charge and follow the above tips to indicate the full charge.

The scooter can be an excellent partner for you when it comes to commuting first in a short distance. Hopefully, this article will help you to keep your scooter’s battery well-performing. The batteries used in scooters are expensive due to their good quality. That’s why electric scooters are a little more expensive.
