There is battery issue in my laptop. I have Original Hp battery.  

Issues i am facing with battery

1. Battery drains quickly

2.Battery Abruptly shut off after 40-45 minutes.

3. Doesn't charge up to 100% . 

4.Battery indicator percentage changes constantly, for ex. If battery charged up to 94% after sometime it will show 89% then again changes to 96%

4. Sometimes battery Backup shows as 6 hr but after some time changes to 2 hr 40 min then again changes to 3 hr 45 min.  

Following are the troubleshooting i have done :

1. Take out battery & checked points - points are totally cleaned. & fine 

2. Check battery drivers for update.- Its already updated.No.update required.

3. Bios version is up to date 

4. Done Hp diagnosis for battery - Showing Primary battery is Ok. No issue. No Calibration needed.

5. Checked AC adapter - working fine

6. Go to Bios setting & done Extensive Test - It passed the test, showing Battery normal. No failure code.

7. Done windows troubleshooting for battery - Result is normal

8. Uninstall Battery drivers & reinstall

9. Take out battery & removed all USB devices. then pressed power button for 15 sec

10. Run full PC scan by antivirus - No threat 

After plugging power cord, battery starts charging. Red LED light shows while charging.

Beside doing all the tests & troubleshooting, the issue is persistent.

I don't know where the problem is.

From what I can tell, since you only gave the generic identification of your notebook, your notebook is between five and six years old. Is that accurate?

A main battery is only warantied for one year of service life. People usually get two years or more of service life out of a notebook battery and yours has exceeded that by a large margin.

Even though the Diagnostics says the battery is OK, the problems you have reported lead me to believe otherwise.

I would remove the original battery and replace it with a new one.

laptop is 4 yrs old.  Battery that came with laptop stopped working in 2019. so i purchased new battery, which is authentic HP battery bought from HP Store. this 2nd battery stopped working in 15 months. 

Hp gave 1 year warranty on battery.

Yes.

Unfortunately, batteries,  across the battery manufacturing industry, only come with a one year warranty.

It is time to replace the battery one more time.
