Laptop Battery Info

The manufacturer's estimate on the amount of time a battery will last (time to fully discharge and overall lifetime) is just an average and depends on a number of factors, some of which you can control. Eventually, the battery must be replaced when it can no longer hold a charge. Below are some tips to help you get the maximum useful life from your laptop battery:

  • New batteries come in a discharged condition and should be fully charged before using, which may take 5-6 hours.
  • To conserve battery life, run your laptop on your AC adapter, especially when using a CD to listen to music or a DVD for video. Also, disconnect any external devices such as an external hard drive, as they can use power even when they are not being used.
  • Set the laptop display brightness to the lowest comfortable setting.
  • When using the laptop on your AC adapter for extended periods, remove the battery and store it in a cool place. If your battery has been in storage, fully charge it again before using it.
  • Use your laptop’s power management features to conserve battery power.
  • Not allowing a laptop battery to fully drain before recharging can create what is called a "memory" of how long it should last. Although Lithium-Ion batteries do not suffer the same “memory" effects of older battery types, you will experience better battery life with any rechargeable battery if you fully drain the battery before charging it again.
