Planning to get a new replacement lithium-ion battery for your motorcycle? Perhaps the previous one just died after you forgot the key in the ‘park’ position? Well, you should probably just hold that thought for a second. Because guess what, you can actually revive your dead lithium motorcycle battery.
Yeah, you heard that right! And it does not matter what the cause of your battery’s failure is. If your battery’s voltage is below the minimum charging level, you could repair it. However, this is only possible if you have the right tools and know what steps to follow.
So, below is a step-by-step guide on how to revive a dead lithium-ion battery for your motorcycle. But before we jump into that, let’s first find out the leading cause of Li-ion battery failure.
What Is The Leading Cause of Lithium-Ion Battery Failure?
It is usually overheating since Lithium-ion batteries are sensitive to high or low temperatures. Typically, this is common when you overcharge your battery and expose it to high temperatures.
Generally, once your battery overheats due to overcharging, the materials inside usually begin to break down. In the process, bubbles of carbon dioxide, oxygen, and other gasses are produced. Pressure also starts to build up, eventually causing your motorcycle lithium-ion battery to swell up. This ends up leading to your battery failing.
How Do You Revive A Dead Lithium Motorcycle Battery?
Thinking of trying to revive your motorcycle’s dead lithium battery before you can get rid of it? We’ve got you covered. Below are steps on how to fix a lithium ion battery.
Step 1: Gather your tools
Before you can start reviving your motorcycle’s dead lithium-ion battery, you need to get a few tools. These include:
- Lithium-ion charger and power source
- Airtight bag
- Working or healthy battery
- Crocodile clips
- Safety gloves and glasses
Step 2: Remove the battery
If the dead lithium-ion battery is still on your motorcycle, you will need to remove it. But first, you must wear your protection glasses and safety gloves. After that, find access to your battery either under the fuel tank or the seat.
Then, start by disconnecting the negative cable first, followed by the positive cable using a wrench. Next, get rid of the safety straps holding the battery so you can gently pull it out.
Step 3: Read the voltage
Next up, get your voltmeter and check the voltage of your lithium-ion battery. If the voltage reading is below the minimum charging level, your battery could be in “sleep mode”.
If the battery is in sleep mode, you will need to jump-start it. But to jumpstart a dead lithium-ion battery, you need a special Li-Ion charger with a booster instead of the regular one.
Step 4: Connect to a healthy battery
If you are not lucky with jumpstarting the battery, you can try reviving it using a working battery. However, you can only use a kit rated the same voltage as your dead lithium battery.
Once you have the battery, get your crocodile clips and connect the two together to recharge dead lithium-ion battery. Leave them connected for 10 to 15 minutes. But be sure to keep a close eye on them because of overheating issues.
Step 5: Re-read the voltage
After 15 minutes, get your voltmeter and check the voltage of your dead lithium-ion battery gain. Your battery should have a relatively higher voltage at this stage. If so, it means the battery can accept a charge.
Step 6: Plug the battery into the charger
Get your lithium-ion charger and charge your dead battery to full capacity. This will take around 3 hours which is the normal charging time for most lithium-ion batteries. Just make sure to follow the manufacturer instructions for recharging. Then, read the battery’s voltage at full charge.
After that, discharge the battery but not below the minimum voltage point. Next, take the voltage readings of your battery once more.
Step 7: Put the battery in a freezer
In your airtight bag, place the battery inside and tightly seal the bag. Then, put the bag in your freezer and leave it there for approximately 24 hours.
Once the 24-hours have elapsed, remove the battery and give it time to totally defrost. This may take up to 9 hours.
Step 8: Recharge the battery
To recharge dead lithium-ion battery, plug your lithium-ion charger into a power source and connect it to the battery. Make sure to recharge it up to 100%. At this stage, the performance of your battery should have improved. As such, it may begin to accept a charge once more.
How Long Does It Take For A Lithium-Ion Battery To Die?
According to most manufacturers, your lithium-ion battery may take anywhere between 3 to 5 years to die when in full use. Or simply, between 1,000 and 2,000 charging cycles.
However, if you are not using the Li-ion battery, you can expect it to last up to 6 years before dying. But of course, this is only true if you take proper care of it and store it away from heat.
Is It Worth Reviving Dead Lithium Motorcycle Battery?
Most people seem to agree that it’s not worth to repair lithium ion battery pack for various reasons. First, it’s because they find the whole process of reviving the battery too demanding. Secondly, even after doing all the work, there is no guarantee that your dead battery will start recharging again.
Another reason why it may not be worth it to fix a lithium ion battery is that the battery may not work as before. Simply, reviving a dead battery does not bring it to its original capacity.
Your lithium-ion motorcycle battery can last for years with proper care. The important thing is you protect it from overheating, which is the leading cause of its failure. You can do this by ensuring you don’t overcharge or expose it to high or low heat.
However, even with their long life, Li-ion batteries do die at some point in their life. But the good thing is you can revive a dead lithium-ion battery. And you don’t need to be a battery expert to do so. All that is required is basic battery knowledge and a couple of tools, including a healthy battery, Li-ion charger, and voltmeter.
