    User Tips:
  1. 1. How to keep my laptop battery healthy?
    Laptop battery packs should be charged for 12 hours when you first get them. Laptop batteries are completely discharged at the time of purchase, and need a full charge before their first use.

  2. 2. How to Extend the Life of Your Laptop Battery
    According to statistics, a typical laptop battery last long for 500 charges / discharges cycles. If you want to your laptop battery last longer than this number, remove the battery whenever your laptop is plugged into an outlet. If you leave it in, the AC power could cause the battery to overheat and overcharge. Also, keep in mind that keep your laptop and battery in cool, dry, and well - ventilated locations. Hot environment might minimize the battery lifetime.

  3. 3. How to deal with my battery when it is not used?
    Don't leave your laptop battery inactive for extended periods of time. Even if you use AC power most of time, use the battery periodically to keep it in good condition. Unplug your AC adapter when the computer is not in use to prevent overcharging.

  4. 4. What should I do for battery storage for a long period of time?
    Don't store your battery for long periods plugged into or attached to any power source, including AC adapters and laptop security carts plugged into an outlet; Charge batteries before storing. The recommended charging time should not exceed 1 hour.

  5. 5. How to maximize my laptop battery performance?
    To get maximum performance from the battery, fully optimize the notebooks power management features prior to use. The power management system conserves battery power by setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it's not in use and causing the machine to go into sleep mode when inactive.

  • Graham Holt on 2019-05-14

    So far so good. I'm getting anywhere from 2.5 to 3 hours or so of life out of this batter on a full charge and that is about what I would expect.
  • Robert Brown on 2019-05-04

    Great product! I was skeptical at first but figured I'll give it a try. Pleasantly surprised. Fully charged I'm getting like 6 hours, I was only getting 3 hours with the original hp battery which would have cost 3 times more than this one. I'm not one to review a product but I made an exception for this one.
  • Sarah Watts on 2019-04-26

    Battery fits perfect however, after 17 days of use

  • Martin Taylor on 2019-03-23

    Product works great. Will purchase again from this seller.
  • Joyce Simpson on 2019-03-15

    This is honestly the first time I've had a laptop that would run on the battery for more than ten minutes! I can charge this battery and use my laptop for several hours. It fits perfectly, works great and I plan on buying another for on the road!
