What is the rechargeable batteries?
Rechargeable batteries, also known as secondary batteries, are designed to be able to be recharged and used multiple times.
Compared to disposable batteries, they are more environmentally friendly, help reduce waste, and contribute to long-term cost savings.
Rechargeable batteries contain various chemical technologies, such as nickel cadmium (Ni Cd), nickel hydrogen (Ni MH), and lithium-ion (Li ion).
These technologies each have their own characteristics and service life.
The key factors determining the endurance of rechargeable batteries
Chemical composition:
Various types of batteries have different cycle lifetimes due to their different chemical compositions.
For example, nickel cadmium batteries can withstand approximately 500 to 1000 charge and discharge cycles, while nickel hydrogen batteries can withstand around 300 to 500 cycles.
The cycle life of lithium-ion batteries is usually between 500 and 1000 cycles, or even more.
The more precise time depends on the usage and maintenance situation.
Usage habits:
The frequency of the charging cycle and the depth of discharge have a significant impact on the lifespan of the battery.
Frequent shallow discharge (i.e. using only a portion of the battery’s capacity) and charging before the battery is fully discharged (completely depleted) can help extend its lifespan.
Temperature conditions:
Extreme high and low temperatures can have adverse effects on the performance and lifespan of batteries.
To achieve optimal performance, rechargeable batteries should be used within the recommended temperature range recommended by the manufacturer.
Overcharging and over discharging:
If rechargeable batteries are frequently overcharged or over discharged, it may cause battery damage and reduce their lifespan.
How long do rechargeable batteries last: different types of batteries

The battery life can range from a few minutes to several hours, and the larger the battery capacity, the longer the usage time.
How long does lithium-ion rechargeable batteries last?
The lifespan of lithium-ion batteries is usually measured by the number of charge and discharge cycles.
A complete cycle refers to the process of a battery from fully charged to fully discharged and then fully charged again.
Most lithium-ion battery designs can withstand 300 to 500 such cycles while maintaining at least 80% of their original capacity.
For devices that are frequently used in daily life, such as smartphones and laptops, if charged and discharged daily, the lifespan of lithium-ion batteries is approximately 2 to 3 years.
The actual lifespan of lithium-ion batteries is influenced by various factors:
Frequency of use:
The more frequently batteries are used, especially in high load applications such as drones, their aging rate is usually faster.
Charging method:
Overcharging, fast charging, and charging at extreme temperatures may all reduce the lifespan of the battery.
Storage environment:
To extend battery life, lithium-ion batteries should be stored in a suitable and dry place at a suitable temperature.
