How long should a laptop battery last?

After the laptop has gone through a full single charge and the power adapter is unplugged, the average life of a laptop battery can be anywhere between one and six hours. This time is dependent on its capacity (mAH), what’s being done on the laptop, and how old the battery is. Over time, the capacity decreases, which means it will not last as long as it did when you first got the laptop and will continue to decrease over time.

The more software programs that are open and running on your laptop, the less time you will get from the battery. When more programs are open, it requires more power for the laptop to keep the programs running. Other factors that affect the battery life include the brightness of the laptop screen, an active WiFi connection for Internet service, and if you are listening to music or watching a video. Each of these will also reduce its life span.

What’s the overall life of a laptop battery?

A battery should last between two and four years, or around 1,000 full charges. It’s total lifetime is dependent on several factors. These factors include battery type (NiCad, NiMH, or Li-ion), how often it is used, and its age.

When should I replace my laptop battery?

It is normal for a battery to lose its ability to hold the maximum capacity as it ages. If your laptop computer can charge it, but it doesn’t last long enough or is only capable of holding 25% or less of its maximum capacity, the battery should be replaced.

Tips and help with maximizing your laptop battery life

Below are suggestions and tips that can be followed to help improve and maximize the overall life of your laptop computers battery.

Full initial charge

After purchasing a new laptop computer or battery for your laptop, we recommend that the battery be charged for no less than 24-hours. A 24-hour charge makes sure it is fully charged and helps with the batteries life expectancy. Once it is fully charged, you should not discharge it fully, if possible.

Remove if not in use for a long period

If you are mostly using the laptop computer while it is plugged into a wall outlet keep the battery out of the computer.

If you do not plan on using your laptop for more than a month it should be removed from the computer, even if it is kept off.

After putting the battery back in after it has not been used we suggest fully charging it before letting it run off the battery again.

Fully discharge and recharge

If your battery is not a Li-ion type it is always recommended to fully discharge and recharge it at least once every month.

Avoid extreme temperatures

Not only is it good for your battery but it is also for your laptop to keep it out of extreme hot or cold temperatures. For example, do not leave your laptop in your car during a hot summer day.

Clean the contacts

Clean your laptop battery contacts with a cotton swab and alcohol every few months.
