The original battery for my old/dated Sony Vaio laptop (model VGN-A790) (battery type PCGA-BP2EA 11.1V/4000mAh) finally crapped out. I ordered a generic replacement from a known supplier (replacement battery type PCGA-BP2E 11.1V/4400mAh/49wh). After I received the battery, I popped it into the laptop -power supply and immediately got the following warning:
The installed battery may not be properly connected to the computer or may not be compatible with the computer. Click OK to place the computer into hibernate and remove the battery.
I followed the instructions and removed the battery. I spoke with the vender who told me that my laptop was an older model and the suggested replacement battery was the one they shipped. I was also told that that as long as they both have the same voltage (11.1V) the difference in the mAh (original 4000mAh – replacement 4400mAh/49Wh) will not make a difference and is safe to use.
I double checked this answer with 2 very well known computer sellers and received 2 different answers.
I them called Sony Tech support and was told I must purchase a Sony battery with the exact voltage and or my computer will be damaged beyond repair.
My issue is I feel I am being forced down the “Propriety” road with Sony Corp. who intends to push their products regardless of the customer’s thoughts. The Sony replacement battery is twice as expensive as the generic ($200.00 plus shipping vice $115.00 with free shipping.)
Can anyone tell me truly what reality is? If the fright answer happens to be go with the generic battery, how can I get rid of the warning (stated above) or perhaps a work around. Any help is greatly appreciated.

This discussion might help.

Sony is dedicated to not allowing any repair or replacement to be done unless they get a cut of it. Every sony device I have ever owned was more expensive to repair than to replace.

The battery may be defective too. The specs seem to be exact enough. If you disable the utility that gives the message, and the battery still does not charge, you should return it.
