Frequently asked questions

How long does a new laptop battery last?
Expect 500-800 full charge cycles (roughly 2-3 years of normal use) before capacity drops noticeably. Keep the battery between 20-80% for longest life.

Do I need to calibrate after installing?
Recommended. Charge to 100%, use the laptop on battery until it shuts down, then fully charge again. Windows will then show accurate remaining time.

Can I install this myself?
Yes. On most HP models you remove the bottom cover with a Phillips screwdriver, unclip the old battery and slot the new one in. Budget 15-20 minutes.
