When was the last time you replaced your battery? A lot of people don’t know much about battery life. Different batteries have different lifespans, and by understanding the lifespan of a battery, we can make better choices about whether to replace or repair the battery when it is damaged. If you do not understand the life of the battery, then in this article, we will take you together to understand the life of various types of batteries.

1. Battery Warranty Life

The warranty life of a battery is the amount of time that the manufacturer promises to repair the battery for free after it has been damaged. General battery warranty time in 1 to 3 years, the specific battery warranty time and brand, battery type. For example, lithium iron phosphate battery warranty time can reach 5 years, while the lead-acid battery warranty time may be only 15 months.

2. Battery cycle life

Battery cycle life refers to the time or number of times a battery can maintain its effective capacity and performance after a series of complete charging and discharging cycles. Battery cycle life is generally uncertain, the cycle life of the battery is mainly related to the capacity of the battery, the charging method, the depth of discharge, as well as the later maintenance. Generally speaking, the 100% charge/discharge cycle times of LiFePO4 battery is about 5000 times, but the 80% charge/discharge cycle times of LiFePO4 battery is about 6000 times to 7000 times.

3. Battery running time

If you don’t know much about batteries, you will easily confuse quality life with runtime. Runtime is the amount of time an electronic device can be used after the battery is fully charged. The longer the battery runtime, the longer the device can run without recharging. Battery runtime varies depending on the needs of the load and is generally difficult to calculate.

4. What is the average lifespan of different batteries?

The main reason we emphasize on battery life when purchasing batteries is because the life of the batteries can be directly dependent on the number of hours and usage patterns they power electronic devices. We’ll walk you through the different categories of batteries.

Disposable batteries do not have a cycle life because they are not rechargeable. The following are the lifespans of disposable batteries

Alkaline Batteries: The most common type of disposable battery, alkaline batteries have a lifespan of 5 to 10 years, but the actual lifespan is related to the power of the device to which they are connected.

Carbon zinc batteries: the service life of carbon zinc batteries is about 2 years, mainly used for low power equipment. If your carbon zinc batteries are left unused for a long time, the service life of the carbon zinc batteries will become shorter because of the temperature, humidity and other factors of the environment.

Lithium-iron batteries: Lithium-iron batteries are the most expensive of the disposable batteries, but lithium-iron batteries will have a higher discharge efficiency and storage capacity, lithium-iron batteries usually have a warranty period of 10 to 12 years, there may be aging phenomenon, but in the case of unopened is able to last 20 years. They will store more capacity compared to the same alkaline batteries.

Silver Oxide Batteries: silver oxide batteries are more common batteries by being used in calculators, watches. The typical lifespan is between 1 and 2 years.

Secondary batteries are not batteries that can be used twice, they are rechargeable batteries the following are common secondary batteries.

Lithium batteries: This is now a more widely used battery, its charge and discharge cycle times of about 2,000 times, of which the common lithium batteries are lithium iron phosphate batteries, lithium ion batteries, lithium polymer batteries. General lithium iron phosphate batteries in all aspects of performance or better.

Nickel-metal hydride batteries: most of the lithium-iron batteries have a charge/discharge cycle of about 500 times, but some brands of lithium-iron batteries can also reach 1000 times of charge/discharge cycle.

Lead-acid batteries: Under normalmente use, the number of charge/discharge cycles of lead-acid batteries is about 200 to 300 times. For new lead-acid batteries, such as AGM batteries, gel batteries, etc., the service life has been extended.

Nickel-cadmium batteries: nickel-cadmium batteries charge and discharge cycle times in 300 to 500 times, but the actual service life is also related to a variety of factors, the main nickel-cadmium batteries overcharge and discharge. If you control the charging and discharging of nickel-cadmium batteries, its service life is much more than that.

Conclusion:

In the process of battery use, it is inevitable to carry out battery maintenance or battery replacement. But for nowadays, if the battery does not happen serious physical bump, and with proper maintenance, generally use more than 5 years is no problem. You don’t need to worry about short battery life. For the above common battery life, I hope it can help you when you choose the battery.
