  • HP battery DM842A Life Tips

  • Does "limited charge cycles" have you worrying about replacing batteries often? Lithium Ion batteries have anywhere from 300-600 charge cycles which is 2-3 years of use for the average user.

  • To get maximum use out of your lithium ion laptop battery there are a few things to keep in mind.

  • Make sure the power saving features are enabled when using the laptop on battery power. These features may be disabled manually for many laptop keyboardif you absolutely need the maximum speed setting for a task, don't forget to turn power saving back on.

  • If you are not going to use the HP DM842A battery pack for a long period of time then try to store it in a cool dry place at about a 40% charge level. Do not freeze!

  • When using the DM842A battery, try to charge it as often as possible as soon as you can.

  • Don't forget your HP DM842A battery in your vehicle on a hot summer day.

  • You should consider buying a spare pack only if you find yourself running out of laptop screen power often, don't buy one to have "just in case". Lithium Ion battery packs start to age as soon as they're produced and can irreversibly lose around 20% capacity per year even when unused. (note storage tip above to minimize this)
