Do Rechargeable Batteries Go Bad If Not Used-Introduction, Charging and Cycle Life
Rechargeable batteries are common in use. It is used in many electric devices and vehicles. Rechargeable batteries are beneficial because they can be charged and used as many times as you want. However, you have to keep one thing in mind, if they are not used for a longer period, they can lose their capacity and go bad.
A rechargeable battery is also called a Storage battery or Secondary cell commonly. It is considered better than the primary batteries.
How long do rechargeable batteries work if not used?A rechargeable battery should be kept in use so that it does not exist in its capacity and efficiency. Some of the different batteries are:
Lithium-ion polymer (LiPo)
Rechargeable alkaline batteries
Nickel-metal hydride (NiMH)
First of all, let's have a look at why such a battery should be kept in use.
The capacity associated with rechargeable battery:
When batteries are used often and kept recharge their capacity is increased. If you do not use the battery for a longer time and it is kept unused, it can lose its capacity and efficiency. The performance of the battery is also affected very badly.
There is a phenomenon in the world of batteries which is called self-discharge. If these batteries are not used often, they start limiting their own performance.
Batteries are made to be used:
Batteries are made so that you can use them as many times as you want. Rechargeable batteries give you the opportunity to use them multiple times.
The life of the rechargeable battery which is used often is greater than the life of a rechargeable battery that is not used frequently. You should keep using them and recharge them every time before use.
How long do they last?A rechargeable battery can be used efficiently for 5 to 7 years if it is well maintained and frequently used. However, a rechargeable battery that is kept and used can last only two to three years with bad performance and less efficiency. Keep using your batteries if you want them to last longer.
How long do rechargeable batteries stay charged?It depends on the type and purpose of the battery. However General information is given below to give you an overall idea about the rechargeable batteries' life and for how long they can stay charged.
The shelf life of the battery:
When you leave a charged battery on the shelf do not expect it to remain charged even after a long time. The shelf life of the battery remains only for 30 days if it is kept at normal room temperature. Temperature affects the battery very badly; if the temperature is very cold or very warm the battery may drain itself earlier than 30 days.
It is advised not to leave the battery on the shelf for this long. You should keep using it to increase its life and efficiency. You should also take care of the temperature at which it is kept. Such batteries are sensitive to temperature.
Self-discharge phenomena of the battery:
There are chemicals present inside the battery, if you keep the batteries unused, they start reacting together even when the electrodes are not linked. This reaction of the Chemicals inside the battery starts reducing the stored charge.
This phenomenon is called self-discharge of the battery. It is present in all rechargeable batteries. These reactions can also limit the performance of the battery and affect its capacity.
Do not keep the battery unused:
You should not leave the battery for a longer shelf life because it can limit the performance of the battery. Do not let the battery self-discharge itself for a longer time. Self-discharge cannot be controlled but it can be prevented if you keep the battery in use.
Do rechargeable batteries last forever?By using your rechargeable batteries effectively and keeping them well maintained you can increase their life. But always keep in mind that no batteries or machines last forever.
Which battery is the best?The lithium battery is considered one of the best batteries which can be recharged very effectively. It does not mean that it will last forever, you will have to replace it.
Its life is longer than other batteries and it can be recharged numerous times.
It is more effective than other batteries and easy-to-use, but eventually, it will start decaying and its performance will be Limited.
You will have to replace the battery in the end; no battery is made to last forever.
Losing its capacity:
One of the researches says that every time you charge your rechargeable battery, it loses a tiny amount of its capacity. This means that no matter how well maintained you keep it has to replace one day. All you can do for the battery is to increase its life by using it effectively and do not let it lay on the shelf unused.
Different researchers are trying to make such batteries that can last forever. They are examining the different materials used in batteries. It is being said that something is discovered that may Let the lithium-ion batteries last forever.
However, it is not announced officially. Researchers are working on it as different experiments are being done. Maybe in the upcoming years, such batteries are introduced which can work very effectively and last forever.
How to know it is time to replace the battery?When the battery is about to die it will start giving you signals. It may take a lot of time for the battery to get charged. It will be drained in less time and will have no effective performance. The capacity of the battery will be very poor and operating time will get shorter.
If the battery is not used it also loses 90% of its capacity in one year which can damage the battery very soon.
Conclusion:Rechargeable batteries should be kept in use and recharged as many times as you like. If they are kept and unused, they lose their capacity and performance. There are many types of rechargeable batteries and they are widely used. You have to keep them well maintained and take care of them to make them long-lasting.
