battery lifespan

Battery lifespan refers to the period during which a rechargeable battery can effectively hold and deliver power. Over time, with repeated charging and discharging cycles, the battery’s capacity gradually decreases, meaning it won’t last as long between charges. Environmental factors like heat, extreme cold, and how often you recharge also impact lifespan. Typically, a battery lasts several hundred to a few thousand cycles before its performance noticeably declines. Proper care—such as avoiding full discharges and extreme temperatures—can help extend its useful life. Eventually, the battery will need replacing when it can no longer meet your needs efficiently.
