Problems With a Dell Laptop Battery
While laptops are as common as water and the air we breathe, it seems many people do not know how to maintain the most important part of the machine–its power source, the battery. The Dell Inspiron 1525 battery is adaptable to many different versions of Dell computers. Battery problems generally have been the result of poor power management and overlooking other problems, such as a loose power jack.
Types
The Dell Inspiron laptop can use three types of batteries. The four cell, the six cell or the 9 cell laptop battery. The higher the number, the greater amount of stored power. A four cell under typical conditions can last 1.5 to 2 hours. A 6 cell can last 2.5 to 3 hours. A 9 cell can last 3.5 to 4 hours. Determine your average usage and consider whether you need to buy a battery with more cells.(9-cell dell laptop battery : dell inspiron 1525 battery ,dell inspiron 1520 battery,dell xps m1530 battery,dell xps m1330 battery)
Considerations
In addition to considering the amount of stored power available, you should look at the power saving practices of your computer. Go to your “computer control panel”. Go to “Mobile PC or Power” settings. Go to change battery settings. Consider adjusting the settings to “power saving” or “balanced” to conserve battery power.
Prevention/Solution
Clean the battery’s metal contacts with a cloth dipped in rubbing alcohol. This helps the dell vostro 1510 battery run efficiently.
Do not allow your fully charged battery to sit unused for more than two or three weeks. Never let a Lithium-Ion battery completely discharge
In 2006, there was a recall on certain Dell models made between 2004 and 2006 because of problems with certain Sony batteries.
Often it is not the dell mini 10 battery that causes a problem, but the DC power jack. The jack connects the computer to the AC power adapter. If you have dropped or shaken your computer too much, it may have a loose or damaged power jack. Before seeking to replace your computer or battery, check the power jack.

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!

Dell XPS M1330 battery not detected
Dell XPS M1330 battery not detected
Question:”Today suddenly my xps m1330 went down and only power LED was started flashing blue/orange. I presumed that it was due to unknowingly power source was disconnected and now battery is also drained.
I checked the power source and restarted the PC. But still the orange LED was flashing. Checked the dell xps m1330 battery status in BIOS and in windows as well: its shows 99% percent charged. So to test the battery I just removed power sources but again PC went down 
Now the situation is that both BIOS & Windows says there is no xps m1330 battery in the system. Where both at this location it was saying that battery was charged 99%. So I just diagnosed system with In built utility and it returns error code 0146 2000-0146. Seems this error is reflection to disk issue.
Still pc is running with AC power source but can not able sustain for a second on laptop battery. I am thinking this should be H/W issue but it would be great help if anybody has solution or workaround for this issue.”
Same Problem:”In my task bar, my battery icon has an X through it and it is telling me that my battery is not being detected. I have no problems with the power cord. And I have not had any error messages, I can run my XPS M1330 off the battery. A diagnostic check says everything is fine, with the pc and the battery. What is going on?”
Solution:
“The error code 0146 and the battery are two separate problems. First the dell xps m1330 battery problem is simple, it’s bad and needs replaced. It being bad can refer to a developed short, a fail safe kicked in, or it’s simply worn out. It is a battery after all, ad they don’t last forever, the more you use them the quicker they wear out. A bad battery causing an issue is vary common with Dell machines, and a false battery reading with a failing battery is also common. The orange flashing battery light is the indicator that the dell xps m1330 battery isn’t working properly, either by fail safe or wear.
The error code 0146 Is from the short test on the hard drive and indicates the a sector is going bad, and eventually the hard drive is going to fail. At this point, your hard drive may last days, or months. Either way, I suggest that you back up all important data, and purchase a new hard drive for the imminent failure. You might even go ahead and set it up, this way you’ll be prepared when it does go, and you won’t have any downtime. ”
