12 Common Reasons Why Your Battery Is Not Charging
Recently we received messages about EBL batteries not working. Complaints were about the batteries not holding a full charge or seeming to not work upon opening the new box.
Do you ever wonder why your EBL battery keeps failing to charge? You might wonder if the problem is with the charger or the batteries. We are here to provide some simple solutions to why your charger might not provide optimal charging conditions.
You probably already know that you can have nickel-metal hydride (NiMH) or lithium batteries.
The chemical composition of these batteries has similar reasons why they fail to charge. The problems could include a dead battery, wiring issues, or improper placement on the charger.
However, lithium batteries require a deeper check before you start utilizing them. They have a higher chance of becoming damaged, and then they will stop charging.
So, here we will discuss why your EBL battery is not charging and ways to solve the problem.
Why is Your EBL Battery Not Charging
These are the top reasons why your EBL battery is not charging. However, it would help if you remember that your NiMH is not charging correctly for various reasons.
1. A Bad Charger
Like any other rechargeable battery, they will only take in power if you charge EBL batteries with the proper battery charger. Try to charge another rechargeable EBL battery to confirm the charger is the problem. You should stop using this battery charger if the problem is with a different set of batteries.
The cable on the charger could have some damage causing the charger to provide improper voltages. The fluctuations could damage other batteries as a result. The issue of a flawed charger will affect both NiMH and lithium batteries.
2. Use the incorrect battery charger
When you use a charger that is not designed for your battery, you risk damaging the battery or the charger, or both. This can occur because different types of batteries require different charging voltages and currents. For example, a lithium-ion battery requires a different charging voltage and current than a nickel-cadmium battery. If you use the wrong charger, it can overcharge the battery or undercharge it, which can cause the battery to become unstable and potentially dangerous. In some cases, using the wrong charger can also damage the device that the battery powers.
To avoid this situation, always use the charger that came with your device or a charger that is designed to work with your battery. If you are not sure what type of charger to use, refer to the device's manual or contact the manufacturer.
PS: EBL 1.5V red lithium-ion 3000mAh AA batteries and 1200mAh AAA 1.5V rechargeable batteries can only be charged with a dedicated lithium-ion battery charger, these lithium-ion batteries cannot be charged with any other type of battery charger.
3. Incorrect placement of positive and negative terminals of the battery
The positive and negative terminals of a battery are marked and are usually different in size or shape. When you insert the battery into a device or charger, it is important to align the terminals correctly. If you insert the battery with the terminals reversed, it can cause a short circuit that can damage the battery, the charger, or the device it powers.
A short circuit occurs when the positive and negative terminals of a battery come into direct contact with each other, bypassing the internal resistance of the battery. This can cause a rapid discharge of energy and potentially generate heat, which can damage the battery or cause it to leak or even explode. To avoid this situation, always check the markings on the battery and the device or charger and ensure that the positive and negative terminals are aligned correctly before inserting the battery.
4. Poor Connection
A weak circuit can cause your EBL batteries to fail to charge. It could be in the wires connecting the battery to the battery charger. Once you place the batteries in the battery charger properly, it will provide a suitable power flow. Though it is infrequent, an inadequate bond can damage the charger and batteries.
5. Damaged Terminals
You can connect the batteries to the charger properly, but if the terminals are damaged, you will not get charged. The problem develops as the battery charger ages, and there are shorts on the circuit boards.
Also, installing and removing the battery can bend the terminal ends of the battery charger. As a result, you can pull the stops back into place. It will be challenging for the cables to hold power if the ends do not contact the batteries. Therefore, the batteries could charge slowly or fail to charge at all.
6. Extra-Low Battery
Battery chargers can have difficulty understanding how many cells are in the battery when you over-discharge your batteries. So, once you start charging the battery, it can reject any charge. Your EBL battery will lose much of its power-holding capacity over time.
A lot of discharge comes from long periods. Therefore, it is essential to remember to store the batteries properly.
7. A Dead Battery
When a battery is dead, it won't receive any charge. But you have to prove it by using another genuine EBL charger. If the other charger fails, it could be because you have a dead battery. Your EBL battery can die because of old age or power faults.
The errors come from poor usage of your EBL battery charger. They won't take any more power. Also, if the battery charger is short-circuiting, it can damage the cells in your battery.
8. Poor Balancing
Expect this problem if you use lithium EBL batteries. If the cells do not have a proper balance, one will have a high voltage.
The charger can only ensure all cells get a charge to a certain level before being complete. It goes beyond the positive and negative cords.
The soldering on the boards ensures the wires can balance the charge to cells.
9. Needs Full Discharge
When the batteries are removed from the charger and installed, the device powers off rapidly as if the batteries were empty, but the batteries show as fully charged in the charger. These batteries can begin charging after going through the discharge process.
The batteries are protected by low voltage because there is no electricity inside. The original battery charger is a high-current fast charger. The high current almost instantly fills the battery.
The proper charger discharges the battery with a slight current and recharges afterward. The charger in the video is a high-current charger with a 1A charging current.
Our EBL906 this charger has a discharging function. After discharging, the battery will automatically begin charging. You can let this EBL 906 charger charge, remove the battery 2-3 times before putting it into the device for use, and check that the battery can work well.

10. False Peaking
You'll find this cause in NiMH batteries. As you charge NiMH batteries with an EBL battery charger, it will check the voltage peak-to-valley range.
When everything is correct, it maintains the proper voltage. But sometimes, the battery will peak. The charger will observe if the battery has a charge or not.
Your NiMH batteries won't hit their peak levels. It happens when the peak-to-valley range is vast. Such issues arise when you don't use the battery for a long time.
11. Broken Or Dead Fuse
The lithium and NiMH battery chargers can not work with a dead fuse. Not all battery chargers have them, but if you need to check the fuse, it should be on the front.
Remember, a fuse may blow because it is old or an electrical impulse damaged it.
When the fuse is dead, the battery charger will not have access to a power flow to charge the battery. If such happens to the batteries, it will be challenging for the charger to charge them well. Simply changing the fuse will fix this issue.
12. The Battery Is Old
If you check the above causes and your battery Battery isn't charging, the battery could be old. It applies to both EBL NiMH and lithium batteries.
The EBL batteries can serve you well for around 300 charge cycles. You can also equate it to two years. Once the batteries are old or damaged, they lose their prime functionality of picking up and holding a charge. You will need to replace the batteries if they are over two years of age.

Will my ebl lcd super quick universal charger charge the ebl 3.7v 16340 battery?
When I plug in my batteries to their EBL charger, I watch them as they charge. Once fully charged I put them in my smart doorbell which tells me they are only at 80%. So remove the batters and I re-plug them back into their chargers and of course, they require more charging.
This time, when I get the notification that they are “fully charged” I unplug the charging base and replug it back in, just to find that there is another hour or so of more charging required. I have reused this method 3 times and each time the indicator falsely reports the EBL batteries are fully charged.
What gives? Why am I getting false full charge results?
Thank you.
when I plug in the charger all the lights turn on green. and they stay on green. with batteries in it and without batteries in it. I bought ebl batteries to go with the charger. when I try the same batteries in my other ebl charger the charger lights will all be off. when I put batteries in the green light comes on, then it turns red to charge, and green when they are charged. I think my charger is bad. its model c808. I bought off amazon.
