How to Make Rechargeable Lithium-Ion Batteries Last Longer – 2024 Guide

We are living in a technology era, where the life of the mobile battery is precious. Therefore, people are curious to find out more about how they can make their rechargeable lithium-ion batteries last longer. The task of preserving the battery is not so difficult. In fact, with the tips that we prepared for you, you are going to know how to take care of the battery itself. If you take care of it, it will operate efficiently and at the same time, you will preserve its’ life.

In general, lithium-ion batteries are the most popular and commonly used ones. They are not used only in mobile phones, but also in cars, to power different electronics tools, etc. However, all of them have common established features that can cause them to stop working. So, if you understand their features you will be able to prolong the battery life. This is incredibly significant if you have some product that does not have a replaceable batteries option.

Battery wear is the term that is used when the battery loses its capacity or increases its internal resistance. As the battery ages, it is able to put less and less amperage. Eventually, this lead to the scenario where the battery is completely unable to generate power – it is empty, and your electronic appliance can not operate anymore. Now, let’s see a few ways how to keep your lithium-ion batteries healthy.

What are the factors that affect lithium-ion batteries’ aging?
  • Time
  • Cycles
  • Storage/operating temperature
  • Charge characteristics
  • Discharging characteristics
  • Depth of charge
  • Time spent at near full/empty
  • Depth of discharge

Understand the lifetime of the battery

We suggest you buy a lithium-ion battery right when you need it because from the moment it leaves the assembly line it starts to age. In addition to that, if you follow the tips we prepared for you below, you will be able to prolong the life of your battery and even double it. It would be a wise idea to check the date stamp on the battery before you buy it and try to get the ones with the newest date released.

What are the charging cycles of these batteries?

The battery cycle includes fully charging and then fully draining its power. You can expect that your lithium-ion battery will last from 300 to incredibly 15 000 full cycles. However, that factor affects the brand and the model of the battery as well.

It is good to know that partial cycles are going to provide you with many more cycles before you see that your battery is dead. Therefore, always do partial discharges when you can and then recharge the battery. One more tip that you should remember is to not intentionally drain a battery power before you recharge it.

What is the adequate storage as well as the operating temperature for these batteries?

You should pay attention to keeping your lithium-ion battery cool whenever you can. That meant that you should avoid storing your mobile phone or some other portable lithium battery in a hot spot or in the sunlight. Always find a cool spot even on the hot summer days. Always find some conditioned shed. For instance, you should always park your electric car in the shade, in a garage, or anywhere else where the temperature is reasonable.

What are the charging characteristics of these batteries?

If you want to prolong the life of your battery you should charge it at a slow rate every time you can. For instance, for your mobile phone, it would be good to use the 1/4 rate of the battery capacity. Additionally, you should avoid quick charging. If you charge your battery at a 1/2 rate of its capacity per hour, you are not harming the battery’s life. However, if you charge your phone in under 1.5 hours from a completely empty battery can lead to damage.

One more thing that you should know is to use a slow charger for power tools instead of the quick ones. Finally, one of the biggest mistakes that people are making is leaving their device connected to the charger after the charging process is complete. In fact, not only that you should instantly disconnect your device, but it is more recommendable to charge it to a maximum of 80%.

What are the discharging characteristics of these batteries?

You should try to avoid harming your battery by pulling as much power as fast as possible from it. For instance, for your EV battery is not beneficial to floore the acceleration pedal constantly. Like that, you should pay attention not to harm your battery by draining the power so quickly. Because of that, it is recommendable to take breaks and to leave your device after some period of usage.

We understand that sometimes it is not an easy task to take the slow path with the battery, especially for some tools such as drills, lawnmowers, or some others that are lithium-ion powered. For these hard devices, manufacturers usually use batteries that are designed for high drain rates and low capacity. However, it is always beneficial to do everything in your power to be gentle and in that way preserve the life of the battery.

When it comes to powering batteries, you should always use the power at a moderate rate.

Those USB models can be very difficult to limit the draw rate since the mobile phone device is going to draw the power completely up to the limit. However, for those devices that do not include a USB feature, you can try to limit how quickly the drawing power is going to proceed.

Finally, you can always decide to buy batteries with a larger capacity rate that you can find on and avoid mentioned problems. If you decide on this step, you should pay attention carefully to whether your device can handle it or not. However, for the same power draw, the battery with a larger capacity is going to have a lower drain percent per hour which will significantly reduce cycle count.

End of lithium-ion battery life

When you see that your battery can not perform the function that you are requiring, you should know that it is a signal that the end of the battery life occurred. In addition to that, if you notice that your battery starts to act unusual, it means that it is ready to be replaced.
