I have Li-ion Battery for my hp laptop. how can I resurrect it's charging ability?

Question

I have a hp laptop (zx5000 series) and it's Li-ion batterty is an hp battery from series : HSTNN-YB02 (for use with series of PP2200 OR PP2210 family of computer products). After working for more than 1 years now my battery starts to de-charge very quickly and it doesn't work as previous. I want to know How can I resurrect it's charging and working ability again ? Is there anyway to repair it ?

Answer 1

I once read about a device with which reconditioning may be achieved 90% of the time on some types of batteries by applying a very brief, high voltage pulse (kinda like a camera's flash system) across the terminals of individual rechargeable cells. I tried an improvised version of it with NiCD and sealed lead batteries, and it seemed to work most of the time. I couldn't find plans for the device when I searched just now, though, so I can't really tell you more than that. Unless you're knowledgeable in the field of electronics, I suggest you just get another battery because the method of recycling I just described may be dangerous.

Answer 3

Give it a full charge. Then use it use it in Windows until you get to about ten percent battery left. Reboot the PC and hit F8 and start it in Command Prompt only. Then let it sit there until the battery runs out. Do this about five times and if it helps you are good to go. If not you need a new battery. If you cannot get to the Command Prompt only for some reason boot to a CD or floppy that does not have an operating system.

The reason these batteries go bad (I think) is because you run the laptop on power all the time not letting the battery run down.

Hope that works. Good Luck

Answer 4

A lithium Ion battery does in fact have a life span. Usually they are longer than one year however.

It would be very hard to ressurect, and I would reccomend buying a replacement.

For all laptop owners who read this, to maximize your laptops battery life, a complete battery discharge is reccomended at least once a month.

Running your laptop on AC power for too long will cause battery electron-dwell and can cause clusters of electrons to become discharged and turn into neutrons.

This reaction will cause significant decrease in battery life.

Answer 5

That is the problem with them. You are about the replacement point. Most laptops get used way too much running on battery power when AC is available and so the battery only lasts about a year.
The OEM's just love it, they sell a lot of batteries. Why do you see printers so cheap (and even free with a new computer), they make their money on the ink!!!

Being an former employee of radioshack for 2 years (before they converted from smart electronic-savvy employees with know-how to pushy ignorant salespeople) I can help you here

there is a chance you can resurrect your battery by draining it dead, then charging it up to full power, then draining it, then charging it up, then draining it....and so on and do on.

Each time you drain it, it will take a little bit longer to drain, and charge up. this is how you know it works.

I have successfully used this method to ressurect an old cell phone battery as well as maintain 2 lithium ION batteries.

Answer 7

They say by allowing it to drain all the way before recharging, increases the batteries staying power. I have not had the occasion to try this as yet but it does stand to some reason.

Answer 8

Time for a new battery, they dont last forever! Please dispose of the old battery thoughtfully, it may be recyclable. If the battery is still under warranty you may be able to get a replacement. Good luck! Look at the link!

Answer 9

no...the lithium ion chemistry has no known method of rejuvenation...throw out time.

Answer 10

drain it and charge it for 4 hours if it still crap buy a new one
