The following two paragraphs are excerpted from my previous closely related question with the title: "Notebook Battery (new) Not Charging". See 07/29/11 03:55 PM, ID: 27229477 if you want more details.
"In June, I bought a refurbished Dell Latitude D410 Notebook.for a special need involving light use. It has Win XP Pro.
All seemed well, but after 5 or 6 weeks, it would run on the battery only a few minutes before shutting down. I bought and installed a new battery, and it charged up fine. At full charge, the battery indicator icon on the XP screen indicated 3 hours run time. But, after about 2 weeks, the battery suddenly wouldn't take a charge."
After discussions on Expert Exchange, I concluded the new battery was defective, and returned it to the vendor and received another battery.
NOW HERE IS THE QUESTION FOR THE NEW/CURRENT PROBLEM
The same thing has happened with this second new battery. After about 2 weeks, the battery suddenly wouldn't take a charge.
There are three possible causes. One, that I've received two defective new batteries from a reputable vendor, seems quite unlikely.
The second is that the charger (Dell brand that came with the refurbished Dell PC) ordinarily works fine, but every week or so is putting out a "voltage spike" (or some such phenomenon) and frying the batteries. (keep in mind, everything was OK for the first several weeks I was using the system.) I could buy a new charger on the chance that it is the problem, but first I would like to get some comments on the third possibility which is that:
"You get what you pay for". Is the Dell Latitude (mine is a refurbished D410) known for this kind of problem? Should I give up on trying to use it with a battery? There is a Dell Application Driver, Quickset, which I could download. Does anybody have any experience with it?
I would appreciate any information or suggestions.
Please note that the voltage, etc. on the charger that I have checks out OK. If it's the charger that's the problem, it's something intermittent/episodic.
