How long should a portable battery last?
The life of a portable battery is a relatively complex issue because it is affected by many factors, including battery type, quality, usage, storage conditions, and maintenance.
The service life of a portable battery is usually 1 year to more than 10 years, depending on the type of battery, brand quality, storage conditions, and usage.
For rechargeable batteries, especially lithium-ion batteries (such as mobile phone batteries, laptop batteries), the general shelf life is about 1 year to 3 years. However, batteries with better brands and quality usually have a longer shelf life. It is recommended to keep the battery power between 20% and 80% during use to avoid overcharging and discharging, which helps to extend the battery life.
For portable devices such as outdoor power supplies, the life of lithium batteries used can reach more than 10 years. The cycle life of this battery is usually still usable after 1500-2000 times, and with the continuous advancement of lithium battery technology, the cycle life will be even longer.
In summary, the service life of portable batteries is affected by many factors, including battery type, brand quality, storage conditions, and usage. In order to extend the service life of the battery, it is recommended to adopt proper storage and usage methods, such as keeping the battery power within the appropriate range, avoiding overcharging and discharging, and storing in a dry and cool environment.
