Numerous accidents involving lithium batteries are reported due to their widespread usage. However, not all battery failures result in severe accidents. Sometimes, batteries simply grow enlarged and are no longer usable. Therefore, you must buy a new one. However, there are certain problems that might not need replacement. It is feasible to address these issues and extend the battery’s lifespan.
Consequently, if your lithium battery is not functioning, you may check the issue. If the problem is simple, it can be resolved simply. If the remedy fails, you may just purchase a replacement. Therefore, if you want to buy a new battery, check this out beforehand.
Problems with Rechargeable Batteries that Happen Often and How to Fix them
1 – Low voltage
A low voltage is one of the most common problems with batteries. The battery won’t work well if the voltage drops below 2V. Also, it will start to hurt the battery’s structure from the inside. Because of this, your battery will only last a low service.
The best way to fix problems with low voltage is to get a battery charger. This will give you the ability to recharge your batteries whenever you need to. So, you won’t need to buy a new one. You can instead recharge it so you can use it for longer.
And if you want to know where to buy it, you can go to eblofficial.com, where you can find one of the best smart battery chargers for 9V AA, AAA, Ni-MH, and Ni-CD batteries. But make sure your batteries are rechargeable. High self-discharge is one reason why a battery’s voltage is low. So, if your battery has high self-discharge, it won’t work for long. You can, however, charge it to make it last longer. One thing to watch out for is that you have to use the charger that goes with the battery. You won’t get anywhere with a universal charger. Instead, it will be very dangerous and could lead to a major accident.
A low voltage can also be caused by a current supply that is not steady. This could be because of the charge or the resistance of the contact. This isn’t a problem with the battery, so don’t think that the battery isn’t good. You can solve this problem with a charge.
2 – Heavy internal resistance
When two systems employ different pieces of equipment, the internal resistance between them might increase. Therefore, internal resistance will increase if the detection precision is inadequate. If you can’t get rid of the contact resistance, you’ll have the same problem.
Longer periods spent in storage are another factor that contribute to a rise in internal resistance. Long-term storage of batteries results in significant capacity loss and internal passivation.
Its activation is the answer to this problem. In order to avoid this issue, it is important to regularly charge and discharge your batteries.
An increase in internal resistance may also be caused by abnormal heat. Since lithium batteries may easily overheat, it’s important to store them in a cool place. They should also be kept away from any spot or ultrasonic welding. To put it simply, exposing a lithium battery to too much heat causes the diaphragm to shut abnormally and the internal resistance to increase. This may occur throughout the production process. That’s why it’s important to keep batteries out of the sun and the oven. In addition, production facilities should exercise extreme caution throughout the welding process.
3 – Lithium battery expansion
You should be aware that lithium batteries expand when charging. This expansion is natural and occurs at a rate of 0.1 mm or less. This will have no negative consequences. However, if the batteries begin to expand over that limit, there will be a problem. The electrolytes will decompose as a consequence, increasing the internal pressure of the battery. It will eventually expand unnaturally.
Preventing overcharging is the best solution to this problem. You should keep track of the time and be quite cautious with it. It will begin to expand if you charge it for more than 12 hours.
Another source of expansion occurs during the manufacturing process. As a result, there is no problem on the user’s end. Overheating and short circuits are examples of processing anomalies. Such problems will cause internal heating, which will dissolve the electrolytes, causing the battery to expand.
One of the reasons of expansion is also circulation. The thickness of the battery will increase as the number of charging and discharging cycles increases. The battery will gradually keep in size until it reaches 50 weeks. The increase will end after 50 weeks, and the battery will be increased by 0.3 to 0.6 mm from its initial size. Because this is a natural problem, there is no solution. Natural expansion may be reduced if the manufacturer raises the thickness of the casing or decreases the internal material. As a result, this solution is intended for the manufacturer.
4 – Explosion
This is the leading problem of fatal accidents. Because of this, you need to use extreme caution while handling batteries. The batteries have a detecting cabinet and a safety circuit; if any of these systems fails, the battery is liable to explode. Simply put, if the charging voltage suddenly spikes too violent, the electrolytes in the battery will breakdown, and the battery will explode. If the internal pressure continues to keep, an explosion will occur.
Many people have been severely hurt beyond repair by explosions of this kind. So, don’t escalate things to that point.
Overcharging is a contributor to the problem from the perspective of the customer. Therefore, you should monitor the charging time of your lithium batteries. You shouldn’t leave them alone all night. Additionally, you can charge it anywhere you can put an eye on it.
