More Details On The Ways To Revive A Motorcycle Battery

Step 1: Taking safety precautions. The battery from a motorcycle has sulfuric acid, which is proven to be a very toxic chemical. Always remember that you have to wear gloves and goggles. You must also consider working in a well-ventilated area.

Make sure that there are no open flames and keep this out of the battery area. Always remember to cool the battery in room temperature before you start working on it.

Step 2: Disconnecting the battery. After taking all the precautionary measures, you can now remove the battery from the motorcycle. When you are on this stage, you will need a small crescent wrench to loosen up the connectors of the cell. You have to remove the little caps on the top of the array and start draining the battery fluid in full.

Step 3: Preparation of the solution. In this stage, you will need and Epsom Salt. You must prepare the solution of at least 8 ounces of Epsom Salts and a quart of distilled water. Distilled water is recommended because it will be easier to dissolve Epsom salts. One way to dissolve it fast is to heat the water first for about 130-degrees Fahrenheit.

Do not use tap water in batteries because it has chemicals that can slowly damage the battery. A plastic funnel can be used to fill each cell. Then, you must shake these batteries gently to ensure that the solution made is evenly distributed in the array.

Step 4: Charging the battery. You must place the battery on a six-volt charger, or a slow charge option for you. Never use a regular charge rate as you do with a car battery. Motorcycle batteries are a lot smaller, and the power charging current will eventually damage the battery, and a flammable gas will be produced.

It is advisable that you start with by turning off the battery charger before you hook the positive terminal to the positive lead and the negative lead to the negative terminal. The battery caps should be off during the charging stage.

Set the charger on low and leave the battery overnight until the charger indicator states that the battery is full. You may reinstall the battery in your motorcycle and check if the connectors are well-secured. Your battery should operate normally now.

These are the simple steps that you need to follow if you revive the motorcycle batteries. Always remember that when you work with batteries, you should still practice with caution. Cells are highly hazardous and toxic material.

Warning When It Comes To Reconditioning Batteries

Reconditioning batteries is not an easy task. One should have adequate knowledge and skills before performing the reconditioning. If you are not so sure of what you will be doing, it will be advisable to ask an expert to do the reconditioning for you.

Here are some tips and warnings before you recondition your batteries:


When you use your motorcycle batteries longer than a week, you must put them in a trickle charger to ensure that your battery will still work despite being idle for a long time. When a battery is stored, it will gradually lose its charge, which will allow the sulfur to form on the battery lead plates.

To be able to restore the battery in its maximum capacity, you have to put it on a charger for three to four nights.


The only warning sign that you should remember in reconditioning battery is that you should NEVER use tap water to your cells, it has certain chemicals that are incredibly harmful to the battery.

Another Way To Bring Back a Motorcycle Lead Acid Battery: Using Epsom Salt

One practical and sure way to bring back a lead-acid motorcycle battery back to life is by using an Epsom Salt. This process is a DIY solution in reviving a dead battery that has not been in use for a long time.

Procedures In Doing This

1. Drain the cell. By using a syringe or dropper, you can carefully drain each cell one at a time until they are 50 % -60% full. If some of the cells are already lower, you can exchange some of the acids from the entire cells.
2. Extract the liquid. Be reminded that you have been taking too much out or you will be struggling to exchange with the acid of the full cells. The juice that you extract is a strong kind of acid so you will need to place this in a glass container. Dispose of the old battery safely and remember not to mess anything of it on your hands and clothing.
3. Preparing the Epsom Salt Solution. You will need Epsom salt and distilled water. Boil the water and stir in more salts until there is nothing more to dissolve. Fill the cell with the Epsom salt solution up to the full level using a syringe or a dropper.
4. Charge the battery. Charge the battery while you are reconditioning it. Some of the gas will be released, so I advised that you leave the caps open while doing the procedures. Try to connect the battery charger to the terminal until it completes the cycle. When the battery is very drained, you have to charge it overnight using a trickle charger with low amperage. (For more information, click here to learn more about it).
5. Clean the battery. Your newly reconditioned battery can be used for another six months up to a year. You can continually restore it by using the same method for up to five times until you can no longer use it.

Tools You Need

You will have to use specific tools in performing this battery reconditioning. It is either you use a voltmeter or a multimeter in reconditioning batteries.

Voltmeter Or Multimeter: Why You Need Either Of These?

These tools are essential in our charging needs. We use the voltmeter or a multimeter in measurements of the right voltage and amperage of the charge and the battery. But what is the difference between the two?

Let’s find out what is the correct use for each of them.

A voltmeter. It is a tool that we used to measure the difference between the two nodes of the electric circuit. Some voltmeter is used to test direct current, and the others are for measuring alternating current or AC. There are some unique versions which can be used for testing and measuring radio frequency voltage.
Multimeter. For this tool, it can measure a combination of measurements in a single device. These measurements vary from Volt-Ampere-Ohm testers that can measure current, voltage, and resistance to most of the sophisticated gadgets which can also show the temperature, frequency, capacitance relative humidity, and acidity.

The basic multimeter works the same way as the voltmeter. There is a dial on the multimeter that will allow you to choose which parameters and ranges that you want to measure.

Battery Charger Or Power Supply: How Do These Help Recondition A Motorcycle Battery?

1. Battery Charger. The process of refurbishing your batteries includes getting rid of the sulphation that has developed. You need to have some time to break down the sulphation from the battery plates. We have to do this to ensure the correct charging process of the battery.

You will need a desulfator, and a battery with a voltage between 6 to 10 amp is one of the best choices. In doing the process, you have to connect the cells with the charger and a desulfator. You have to charge it with a specific gravity between 1.250 and 1.300.

2. Power Supply. A power supply can be a big help in the reconditioning process of a battery. If you are using a lead acid battery, using this method is possible to refurbish your batteries.

When you connect the battery, try to compute the battery’s charge voltage against the number of batteries that you put in a series. Get the voltage that you desire and limit of the current that you want..

Choose the charge current depending on the battery size. Observe battery temperature, energy, and present during the charging state. Charge in a well-ventilated room. Disconnect the load once it is complete.

Remember that you should monitor the charging process while using a power supply as this can overcharge your batteries. Both the charger and power supply can help in refurbishing or a battery.
