How to repair a battery that can’t be chargering anymore
How to repair a battery that can’t be chargering anymore?
Sometimes you CAN “rejuvinate” a rechargeable dell xps m1530 battery that doesn’t want to take a charge anymore. You first need to have a basic understanding of WHY the battery is not taking the charge in the first place.
As a battery is used/charged/recharged, it develops little “hairs” of chemical that create an electrical link between the positive and the negative parts inside. This is, in effect, a short circuit inside the battery. If you are trying to recharge the battery, it appears to be charging, but once you take the charger off, there’s still no juice available. This is because of this “short” inside the battery.
I had four rechargeable laptop batteries for an old laptop, and this procedure worked just fine on them. Just note that this does NOT work every time. In my opinion, for every 10 batteries you ‘rejuvinate’, you may end up tossing 3 of them in the garbage! But then, what have you got to lose?
Basically, you will be “burning” out those little “chemical hairs” with a reverse charge.
You will need access to an automotive battery, and a pair of booster cables. You will need to determine the polarity of the dead vgp-bps2c battery …. Which is the positive tab, and which is the negative one on the battery?
Please note that I am NOT RESPONSIBLE for injury or damage to anything! You do this at your own risk. Read the instructions below BEFORE you do any of this!
Do this OUTSIDE, and wear safety glasses and gloves! You can never be too careful!
Put the booster cables onto the automotive battery. The red goes on the Positive (+), and the black on the
Negative (-). Make sure the other ends of the booster cables don’t touch one another. Very similar to boosting someone’s car that won’t start, except we are going to do something different!
Now take your dead hp dv2000 battery, and lay it so you can see the Positive and Negative tabs on it. Best to leave it on the ground, or a flat spot somewhere, rather than hold it in your hands.
What we do next is to apply a very FAST, REVERSE CHARGE from the automotive battery to the dead computer vgp-bps8 battery. The thing to note here is that it is a very quick, fast reverse charge. DO NOT CLAMP the booster cables to the dead battery!
Take the black, Negative (-) booster cable lead, and hold it onto the POSITIVE (+) tab of the dead battery.
Yes, that’s right. It’s backwards. This is half of the job.
Now, take the Positive (+) booster cable lead, and TAP it ONCE on the NEGATIVE (-) tab of the dead laptop battery, and remove it immediately! DO NOT HOLD IT IN PLACE!!!! Your connection here should not be a connection, but just about as long as it takes for you to blink your eye quickly. A QUICK TAP! ….. ONLY DO THIS ONCE!
You may be tempted to do this again, because it might look like nothing happened! DON’T! …. What you just did is apply a very big amount of reverse current to the old dead cell, even though you didn’t see anything. (at most, you may see a small spark). Hopefully, this was JUST enough to burn the ‘chemical hairs’ off, but not enough to damage the cells in the dell inspiron 1520 battery. That’s why it is important not to hold the lead on for more than a 1/10 of a second, and not to try doing it again.
Remove all leads, put your automotive cell and cables away. Try charging your ‘dead’ sony vgp-bps8 battery now. If the above procedure did indeed ‘fix’ your sony vgp-bps9 battery, it will behave JUST LIKE A NEW ONE!
If not, you can repeat the above procedure a couple of times, and try recharging again.
Works for me!
Just be careful. If you are not technically inclined, have someone who IS give you a hand. Just have them read this before THEY do anything either!
I must say this again – you do the above at your own risk, although I never had any problems doing this myself, I can’t be responsible for anyone else!

How to Make a Acer Laptop Battery Last Longer
How to Make a Acer Laptop Battery Last Longer
Save on electricity and get the most out of your laptop when you aren’t plugged in. Here are ten steps to make your BATBL50L6 laptop’s battery last longer.
#Step 1 Dim your screen
For most laptops dimming is a button on the top row that looks like a sun with a down arrow. Press it repeatedly to reach the dimmest screen setting you can still function with.
#Step 2 Turn off programs running in the back ground that you aren’t using
Programs like Itunes, chat programs, Windows Customer Experience Center. All of these take laptop battery life to run, you can extend your battery juice a little bit farther by turning them off. You can even go so far as to set them up not to auto start. This will also decrease the amount of time it takes to start up your computer. If you use an email program like gmail or yahoo you can choose to turn off the chat functions and run on the html setting. You will need to manually refresh to see updates, but you will use a lot less energy.
#Step 3 Run off a hard drive or jump drive rather than a CD or DVD
CDs and DVDs need to spin to function. Spinning takes energy. Hard drives and jump drives don’t spin.
#Step 4 Turn your computer off or to hibernate mode
A “sleeping” computer or a computer on standby is still using quite a bit of energy so that it can start up quickly right were you left off. To conserve the most energy turn it all the way off or set it to hibernate.
#Step 5 Optimize your power settings
Most laptops have a power setting option. Click on the AS07B41 battery icon on your desktop (mine’s in the lower left corner) and you should get the option for several power modes. Choose the one that is called “power saver” or something similar. Some laptops will automatically switch when they aren’t plugged in.
#Step 6 Don’t use sound
Turn the sound off on your computer – it takes up to seven times more energy to play sound than just use the screen of your laptop. If you must have sound, use your headphones. They take far less energy.
#Step 7 Don’t have multiple programs running
When you are working off your Acer Aspire 5920 battery use only one program at a time. Email that refreshes itself constantly can be a big drain on the battery, so close it when you aren’t using it directly.
#Step 8 Keep your temperatures down
A hot computer is an inefficient computer. Use the canned designed to clean electronics to clean out the vents. They are often on the bottom of your laptop. Also if you are using your laptop on a soft surface like a pillow you maybe blocking those vents and your computer isn’t cooling properly. Get a lap board or a large notebook to set your computer on instead.
#Step 9 Defrag your hard drive
You can have a more efficient computer not just in how fast it can do the tasks you give it but in the energy it uses by simply defragging it. Apples tend to not need as much defragging as PCs.
#Step 10 Get a new battery or new computer
Older batteries tend to not hold charge as well. If you have had your battery or used it a lot you may benefit from a new one. There are also lots of new laptops out there that are super efficient. Many are built specifically for use on Acer Aspire 5720 battery alone. If you will be working often without a power source make it a priority in your next computer.

Maximize your laptop battery life
Collected by www.diggingshop.com
When I first got my laptop 1 year ago , my laptop battery life was about 3 hours. Now after daily use (mostly with plug but using battery as well) it is down to 1.5 hrs which is basically useless. SO I am buying a new dell d620 battery from diggingshop.com?the battery shop suggest:
“New dell laptop battery come in a discharged condition and must be fully charged before use it. It is recommended that you fully charge and discharge your new dell laptop battery 3 times to allow it to reach its maximum rated capacity.
Rechargeable battery will undergo self-discharging when left unused.Don’t store notebook batteries completely discharged.It should always be stored in a fully charged status and kept in a cool, dry and clean place.
Fully charging and then fully discharging it at least once every two to three weeks.With lithium-ion dell laptop batteries, partial charges and discharges are best on a regular basis. These batteries do not suffer from the memory effect.
With the use of your dell d620 battery, the battery life will be shorter and shorter.How to keep the battery a longer life is the primary problem that the computer users should pay attention to ”
It turns out that the single, most important aspect to maximizing a laptop battery life is something that I wouldn’t have thought of: matching the battery to its charger. In the diggingshop.com’s words: “Make sure your laptop battery and adapter match and you have a quality adapter.”
That, further, minimizes any manufacturing differences that may occur over time.
The number two factor in laptop battery life? Temperature.
The fact is that laptops just aren’t designed for … well, for laps. If you look at the bottom of your laptop you’ll see it probably has feet (or more likely, bumps or rubber pads) that lift it off of any flat surface you might put it on. That creates very important space for ventilation. If you block that space, with say your lap, it’s likely that you’ll be causing the laptop to run hotter than it should. If you do this regularly, you’ll likely shorten the lifespan of the laptop’s batteries.
Again, in diggingshop.com’s words: “Rechargeable dell d620 battery will undergo self-discharging when left unused.Don’t store notebook batteries completely discharged.It should always be stored in a fully charged status and kept in a cool, dry and clean place.”
Temperature cycling – allowing the laptop to become very cold and then warm, repeatedly – say by leaving it in your car overnight in cold weather regularly can also adversely impact the battery’s life.
A concern that I’ve had for a long time is whether or not leaving a laptop plugged in for extended periods of time would harm the battery. Today’s designs pretty much expect that type of usage, so it’s not the issue I was afraid it might be. Good thing, too … my laptop is plugged in and running pretty much 24×7.
Finally: “Dont use laptop battery if it is not necessary because every charge/discharge time may shorten hp compaq batterys life. .”
