Regarding the service time (i.e., battery life) of 12V lithium batteries, the length of their use mainly depends on many factors, such as battery capacity, discharge current, battery load, and use environment. The following is a summary based on the information provided in the reference article:
Battery capacity
The larger the battery capacity, the longer the battery life. For example, for a 12V12ah lithium battery, it has a power rating of 144 watts. However, the actual battery life also depends on the discharge current and load.
Discharge current and load
The size of the discharge current and the load on the battery directly affects the battery life. If the battery is powered to a low-load device with a lower discharge current, then the battery life will be longer. Conversely, if the discharge current is high or the load is high, the battery life will be shortened.
Use environment
The environment in which the battery is used, such as temperature, will also affect its performance. In high or low temperatures, the performance of the battery may be
degraded, which can affect the battery life.
Specific to the battery life of 12V12ah lithium battery, it can have different performance according to different use conditions:
When used in summer, the power of the battery can be fully released, and the battery life is relatively long, about 3 hours.
When used in winter, the power of the battery cannot be fully released, and the battery life is relatively short, and it may only be used for about 2 hours.
In addition, the charging time for 12V lithium batteries also depends on the charging current and battery status. If the battery starts charging in a dead state and uses a charging current of 1 amp, then it will take about 12 to 13 hours to fully charge. If using 2 amps
