The battery replacement cycle varies depending on the type of battery and the environment in which it is used. Here are some common types of battery cartridge and their general replacement recommendations:

1. Mobile Phone battery cartridge: The battery of a smartphone typically lasts for about 500 charge cycles before its health drops to 80%. If the battery health falls below 80%, it is recommended to consider a battery replacement, especially if this occurs within a year and is eligible for a free replacement service.

2. Laptop battery cartridge: The battery life of a laptop generally lasts for 2 to 4 years, depending on usage frequency and charging habits. If there is a noticeable decrease in battery life or an increase in charging time, it is time to consider a battery replacement.

3. Automotive battery cartridge: Conventional lead-acid battery cartridge usually last for 2 to 3 years, while maintenance-free battery cartridge can last for 3 to 4 years. AGM battery cartridge have a longer lifespan, typically 4 to 6 years.

4. Electric Vehicle battery cartridge: The battery life of electric vehicles is typically between 6 to 10 years, depending on the battery type (such as lithium iron phosphate or ternary lithium battery cartridge) and usage conditions. It is generally recommended to consider replacing the battery when the battery capacity drops to 80%.

5. UPS battery cartridge: For battery cartridge in UPS systems, it is usually recommended to replace them every 3 to 5 years, depending on the usage environment and maintenance.

Regularly checking the status and performance of the battery and replacing it in a timely manner can prevent equipment failure due to battery issues.
