How do I bring a laptop battery back to life...?

Question

I have a Compaq Presario 2200 (Really old, I know) and I need to bring the laptop battery back to life for about 5 minutes.

I don't have a charger at ALL, and I need this within 5 hours...please help me!!! I'm going crazy!!!

I need this for like 2 minutes minimum, the freezer thing won't work because it requires charging and discharging...

if you can, please contact me ASAP!!!

If I don't get this, I'm completely screwed over...

Answer 1

You don't.

If you need to recharge the battery the only way to do that is with the adapter but whether the battery will even be able to store a charge is another matter.

Oh and putting a laptop battery in the freezer is good for ruining the battery and ruining the battery only.

If you just need to get stuff off the laptop then running it off the adapter (which you're going to need, no matter what) is probably a better way to do things.

If you don't care about whether the laptop will work again you could just get a regulated power supply, set it to whatever voltage the computer has listed as input and then try to plug the power supply into your computer and hope everything works.

Keep turning on the laptop until It will not turn on anymore. Take the battery out, freeze it, put it back in the laptop frozen and start charging to FULL FOR 14 HOURS. Discharge the battery COMPLETELY, AGAIN, freeze it, again, charge it fully, again, and use it completely again.

If you get a new battery, charge it FULLY before you use it and run it down completely (dead as a doornail) before you charge it again. Batteries are capacitors which have electron "memory" the more you use the memory and make it forget, the longer it will remember. If you take a battery, run it down halfway, charge it halfway, and keep doing this over and over, pretty soon the battery will only have half the capacity it use to.

I understand you want to have your own schedule to use your computer.......not your battery's. Say the battery is charged fully, you're around a power outlet, and you will be using the battery later - TAKE THE BATTERY OUT OF THE COMPUTER and save it for later. Plug in the computer and use it without the battery in; the computer will also be a lot lighter. I recommend getting a power inverter for the car with a higher wattage than your computer uses (look in the manual or on the bottom of the computer - 200w should do it) so you can keep charging the battery as you go when you start charging it.

This also applies to cellphones, pagers, pda's, and everything else that uses rechargeable batteries. My cell phone is 3 years old; people who have cellphones as long as I do at my age (20's) usually have a dying battery after 10 minutes - my phone lasts 5 days off the charger.

bestonnet_00 must not know physics as neutrons thaw out, relaxing slowly while the battery is charging, they each get a jolt of protons evenly as they dismantle from the cluster. Keep your laptop upright for this process as condensation may occur internally,

Answer 4

my battery on my computer wont charge when i shut it down the battery light is red

Answer 5

the craziest thing you might be able to do is find any wall charger and the the tip off it off so there is the red wire and black wire and then try and remove the battery from the computer and find the Possitive and negative receptors on the battery..

red wire is usually possitive and black negative and try holding the wires that are plugged into the wall and hold it on the battery receptors....

its a crazy idea!! but hey it might work....

Good Luck and hope it helps!!!
