Battery life for wireless mice and keyboards depends on a variety of factors, such as battery type, frequency of use, use environment, and more. In general, the life of ordinary alkaline batteries is about 3 months, and the service life of rechargeable batteries or professional batteries will be longer. If your wireless mouse and keyboard are used more frequently, the battery life may be a little shorter. It is recommended that you pay attention to the battery power in normal times, and replace the battery in time when the power is low.
