Rechargeable batteries have become an integral part of our lives, powering everything from smartphones to electric cars. However, like any other battery, rechargeable batteries have a limited lifespan, and they will eventually need to be replaced. The lifespan of a rechargeable battery depends on several factors, such as the type of battery, the number of charging cycles, and how the battery is used. In this blog post, I am going to explain each of these factors in detail to help you better understand what determines the lifespan of a rechargeable battery.
Type of Rechargeable Battery on the Market
First, you have to understand the type of batteries you are using. The lifespan of a Li-ion battery is better than a NiCd battery. The type of battery is one of the most important factors in determining the lifespan of a rechargeable battery. There are several types of rechargeable batteries, including:
- Lithium-ion (Li-ion) batteries
- Nickel-metal hydride (NiMH) batteries
- Nickel-cadmium (NiCd) batteries
- Lead-acid batteries
Li-ion Batteries Lifespan
Of these, lithium-ion batteries are the most commonly used in portable devices such as smartphones, laptops, and tablets. They are also used in electric vehicles and other large-scale applications. Generally, lithium-ion batteries have a longer lifespan than other rechargeable batteries and can typically last for several years.
The Lifespan of a NiMH Battery
Nickel-metal hydride batteries are also commonly used in portable devices and have a longer lifespan than nickel-cadmium batteries. However, they are less commonly used today because they have a lower energy density than lithium-ion batteries.
Lifespan of a NiCd Battery
Nickel-cadmium batteries have a shorter lifespan than other rechargeable batteries and are less commonly used today because they contain toxic materials such as cadmium.
Lead-acid Batteries Lifespan
Lead-acid batteries are commonly used in vehicles and have a longer lifespan than other rechargeable batteries. However, they are not commonly used in portable devices because they are heavy and have a low energy density.
Understand the Number of Charging Cycles of Your Rechargeable Battery
Do you know what a charging cycle is? A charging cycle is defined as the process of charging a battery from 0% to 100% and then discharging it to 0%. Each time a battery goes through a charging cycle, it loses a small amount of its capacity. This loss of capacity is known as “cycle life.”
The number of charging cycles a battery can endure before its capacity drops below a certain level is known as its “cycle life.”
The cycle life of a rechargeable battery varies depending on the type of battery, the quality of the battery, and how the battery is used.
For example, a lithium-ion battery typically has a cycle life of 300 to 500 cycles. However, high-quality lithium-ion batteries can have a cycle life of up to 1000 cycles or more. On the other hand, nickel-cadmium batteries typically have a cycle life of 500 to 1000 cycles.
Charging and Discharging Process of Rechargeable Battery
Besides the cycle life, the way a rechargeable battery is charged and discharged also affects its lifespan. Charging a battery too quickly or discharging it too deeply can cause damage to the battery and reduce its lifespan.
Overcharging a rechargeable battery can cause it to overheat, which can damage the battery and reduce its lifespan.
On the other hand, discharging a battery too deeply can cause irreversible damage, reducing its lifespan.
To prolong the lifespan of a rechargeable battery, it is important to charge it using the manufacturer’s recommended charging method. Please remember to avoid deep discharges whenever possible.
Check the Temperature of Your Battery
The temperature at which a rechargeable battery is used can also affect its lifespan. Extreme temperatures, both hot and cold, can cause damage to a battery and reduce its lifespan.
Operating a rechargeable battery at temperatures that are too high or too low can cause irreversible damage to the battery and reduce its lifespan.
Are you using your smartphone while charging? Do not do it!
It overheats the battery, and you know the danger!
Ideally, rechargeable batteries should be stored and used at room temperature, between 20°C and 25°C. If a battery is exposed to extreme temperatures, it is important to allow the battery to cool down or warm up before using it.
How You Store the Rechargeable Battery is Important!
The way a rechargeable battery is stored can also affect its lifespan. Most manufacturers prefer to store the battery in a cool and dry place. Besides that, if a battery is not used for an extended period, it can lose its capacity and eventually become unusable. In such a case, you should recharge the battery every few months to prevent it from losing its capacity.
Please remember the above suggestions to make your rechargeable battery long-lasting. Do you have any other suggestions? Please comment below.
