Here we are going to discuss Why is my battery yellow. So you’ve noticed that your battery is yellow, and it sure isn’t a healthy shade. But have you ever wondered why? And what does yellow mean? Fear not, because I’ve made this post hoping to give you the answers to all of your battery yellowing issues.
If your phone battery is yellow, should you be worried? Definitely, yes. There are actually a number of reasons why a battery can turn yellow, and most of them have to do something with its ability to function properly. Therefore, understanding the condition of your batteries is crucial for ensuring their longevity and performance. Moreover, yellow batteries can be concerning, as it may indicate that the battery is no longer functioning properly. So, to help you with this issue, In this blog post, we will explore the causes of yellow batteries, the impact they can have on your devices, and what you can do to prevent or treat them.

What causes yellow batteries?
The main cause of yellowing is a chemical reaction between the battery’s electrolyte and the steel (tin) in the battery. This reaction is caused by the electrolyte reacting with trace amounts of iron from the steel casing. The result is a chemical reaction that produces hydrogen gas, which forms bubbles that rise to the surface of the battery, causing it to discolor.
Heat and humidity are your battery’s worst enemies as they can fasten the yellowing process, but yellowing can occur at any temperature above freezing. Batteries at low temperatures will also eventually yellow, although it may take months or years for this to happen.
Some batteries are more susceptible to this process than others. Alkaline batteries tend to discolor faster than other types, especially if they’re left unused for long periods of time or stored in high-temperature environments (like car trunks). Lithium batteries are less susceptible because they don’t contain any iron.
Moreover, aging batteries will eventually develop a yellowish tint on their outer surfaces as a result of repeated charging and discharging cycles that expose them to oxygen over time. This process is known as the “memory effect” because it makes rechargeable batteries appear as if they’ve already been discharged when in fact, they still have some charge left in them.
Common causes of yellowing
Apart from aging a battery can get yellow for other reasons like overcharging, high temperatures, and prolonged storage:
Overcharging is one of the most common causes of battery yellowing. It occurs when you overflow your mobile battery with charge or voltage. In other words, when you leave your phone charging overnight or when you leave your laptop plugged into an outlet all day long, it causes overcharging, which can lead to battery damage and corrosion.
High temperatures also cause batteries to turn yellow because they reduce their lifespan and capacity. This happens because batteries generate heat while charging, which leads to overheating and ultimately, overheating damages the cells inside the battery, which results in poor performance over time.
Batteries can also turn yellow if they’re stored for too long without being used and not charged properly every now and then.
Impact of yellow batteries
If you’re using a yellow battery in your device, expect these effects:
As batteries age, they become less efficient at holding a charge. This means they’ll likely not last as long as they did when new.
The longer you use your device with a yellow battery, the worse it will perform. Batteries that have turned yellow may not be able to power up your device or could take longer to do so than they would if they were still white or green.
Over time, batteries lose capacity even when they aren’t being used. However, this process is sped up by exposure to heat and light and by charging them frequently before they’re fully drained (which causes them to overheat).
The problem with yellow batteries is that they can cause damage to devices or even cause fires. This is why it’s so important to make sure you are using the right type of battery when it comes time to replace your old ones.
The last issue with using a yellow battery is cost. Yellow batteries may cost less than other types, but this doesn’t mean that they are any better for your device or yourself.
Prevention and treatment
The yellowing of the battery can be caused by a number of factors.
Overcharging is one of the most common causes of battery yellowing. It’s best to use a quality charger that is able to detect when the battery has reached full charge and stops charging before that point. This way, you won’t overcharge your batteries and it will increase your battery life.
Heat is another factor contributing to battery degradation. If you live in an area that gets very hot during the summer months, it’s best to store your batteries in a cool place, so they don’t get too hot in the sun or from the heat generated by other devices plugged into them (e.g., a laptop).
Using high-quality batteries
There are many cheap brands out there that claim to be compatible with your device but don’t actually work well with it or may even damage your device in some cases! We recommend buying only high-quality batteries from reputable brands such as Samsung®, Sony®, LG®, etc., which have been tested and proven safe for use with your device(s).
Use the right charger
Using a quality charger will help extend battery life because it will charge more slowly and at a lower voltage than an inexpensive charger. This allows for better electrolyte flow within the cell, which keeps electrolytes from forming crystals that can shorten battery life.

As long as the device is not exhibiting any signs of overheating or malfunctioning, there is no reason to fear a yellowing battery. As long as you are using your device correctly and charging it in a safe manner, there shouldn’t be any reason for you to worry. Lastly, I hope this blog post on “why is my battery yellow” gives you all the answers about the health of your battery and what you can expect from its yellow colouration!
