There are more ways than one to charge a scooter battery even if you don\u2019t have a charger in hand. Let\u2019s take a look at some of the easiest options available to you.<\/p>\n
You can use a portable car jumper and hook it up to the battery and charge it in just about 20 minutes. You can also use an adjustable power adapter and charge your scooter. It might take a little longer but if you do it right, it works just fine.<\/b><\/p>\n
But before you pick up your gear and head towards your scooter battery, there are a few things to remember. Depending on the kind of batteries your scooter<\/a> functions on, there are a few precautions to take so that you don\u2019t end up damaging the battery accidentally. Let\u2019s see how it\u2019s done.<\/p>\n Charging a scooter battery<\/a> is possible. There are two easy ways to do it. We will take you through the step-by-step process of charging your scooter battery<\/a>.<\/p>\n This is one of the easiest ways to charge a scooter battery<\/a>. Their large and portable built-in battery<\/a> comes in very handy when you need a quick jumpstart. Now, the voltage is a lot higher than your scooter<\/a> needs. So, there\u2019s that to consider. Here\u2019s how you go about it.<\/p>\n Step <\/b>1:<\/strong> Connect the battery of your scooter<\/a> to the jumper. You do this by connecting the electrodes of your battery to the jumper cables<\/a>. Connect the positive charges first and then the negative.<\/p>\n That means start by connecting the red cable to the positive electrode of your battery and the black<\/a> cable with the negative. Make sure they are done right and fit properly before proceeding.<\/p>\n Step<\/b> 2<\/b>: <\/b>Turn the jumper on which will start the flow of current into your scooter<\/a> battery. Keep it steady for about 20 minutes. Now this time frame also depends on the kind of battery you are trying to charge<\/a>. So, you must check the instruction manual of your scooter.<\/p>\n You must also remember that when the battery starts to feel hot, it is getting overcharged and you must remove the cables. Otherwise, you risk damage or depletion in the battery\u2019s life in the very least. Now, the latest models of some portable chargers actually come with a digital control unit which can manage the amount of current flowing into the battery. See if your unit has one of those and monitor it.<\/p>\n Step 3<\/b>: <\/b>Remove the jumper after the right amount of time (which you must have figured out by now). Start by disconnecting the black cable from the negative electrode and then the red one from the positive<\/a>.<\/p>\n The second efficient way to charge your scooter batteries without a charger is to use what is called a universal power adapter<\/a>. This is a device which stores electrical charge<\/a> for a certain amount of time. And this is how you use it.<\/p>\n<\/div>\n This is not so much a third method as it is the way you should deal with the different batteries that run<\/a> your scooter. Now, this might feel a bit tricky and technical but it is really not. Let\u2019s see what we\u2019re talking about.<\/p>\n If you are trying to charge a lead-acid battery<\/a>, you need to start by calculating the voltage. And be as accurate as possible. This can be done by checking the number of cells in each battery.<\/p>\n What you must do is connect them to the power supply and set the voltage<\/a> and output current to the desired levels. So, if you have a 12-volt battery with six cells and each of them is nominally 2 volts, you need to set the output voltage to 12 volts<\/a>.<\/p>\n Next is selecting the charge current. For this, check the size of the battery. A standard lead-acid battery requires the current to be between 10-30 percent of its rated capacity. So, if you have a 10 Ah battery and it needs<\/a> to be set at 30 percent (which is the maximum), you are looking at 3 amps.<\/p>\n When using variable power supply, check the voltage, flow of current and also the temperature of the battery as it is being charged<\/a>.<\/p>\n You will know that the battery is charged<\/a> when the current drops to 3 percent of the battery\u2019s rated capacity. And finally, remove the charger.<\/p>\n The process of charging your batteries also leads to reverse sulfation<\/a> when applicable. This is a process that occurs when the batteries have a layer of lead<\/a> sulfate crystals on them. That\u2019s not supposed to happen. But when it does, it can cause battery<\/a> failure.<\/p>\n So, when you start charging your battery<\/a> again, reverse sulfation might occur. If that is a possibility, you must set the voltage a little higher than what we just mentioned as it takes a little while for the layer of sulfation to dissolve and then the current starts to flow to the cells.<\/p>\n This is a very popular choice today for most electrical equipment because they produce less heat, save power and are flexible. They are also cheaper than the lead-acid variety and hence found their way into scooters too.<\/p>\n Now, before you start charging these batteries<\/a>, once again, you must determine the full voltage of each cell in the battery. Usually that is 4.2 volts per cell which means your input voltage and power supply must not be more than that. Charge your batteries<\/a> and you will know when it is done once the power supply falls to 3 percent of the battery\u2019s rated capacity. At that point, each cell will be charged to 4.2 volts, exactly what you want and you are now good to go.<\/p>\n But the difference between charging a lead-acid battery<\/a> and its lithium-ion counterpart is this. Make sure that if the cells are connected in series, their maximum voltage is not more than the full charge voltage.<\/p>\n And finally, you have the NiMH and NiCd batteries<\/a>. You might want to be extra careful with these when you are not using a charger. You can charge them with adjustable power supply but detecting the full charge is a pretty challenging task because it varies with charge current.<\/p>\n While you are charging them, keep checking the levels of remaining charge (this will be an estimate). If you are charging a standard NiMH battery<\/a>, it might take about three hours. Use a voltmeter to make sure the voltage reading is accurate. Typically, you will see it in the 13.7 to 13.9-volt range. If you are seeing numbers less than 12 volts, you are dealing with a depleted battery.<\/p>\n You can use the same power sources mentioned above for razor scooters too. But you will need to remove the battery<\/a> from a casing in the motor compartment. For that, you will need a battery charger<\/a>, screwdriver and a power supply cord.<\/p>\n<\/div>\nHow To Charge Electric Scooter Without Charger?<\/h2>\n
