1) To maintain the optimum performance of the COMPAQ 134111-B21 Laptop Battery, it is highly recommended to circle (fully discharging and recharging) it at least once a month. Note: It is normal if a new COMPAQ 134111-B21 battery gets warm when being charged or used.

Make Your Laptop Battery Last Longer: 3 Things to Know

1. Most laptop batteries start to fail in 1-2 years. This varies depending on your usage, of course, but the average laptop battery is good for around 400 recharges (a.k.a. cycles). After that, it starts to lose its capacity to hold a charge.

2. You can extend the life of your current battery. If you use your laptop as your primary desktop PC, you may be wasting battery cycles by leaving it plugged in all the time.

The solution: pop the battery out until you actually need to go somewhere with your laptop. As long as the latter is plugged into an AC outlet, it doesn't actually need the battery.

3. Investigate third-party alternatives. When you do end up needing a replacement battery, you don't necessarily have to buy one from the laptop manufacturer--paying top dollar in the process.
