My laptop model is Benq S31V (battery model SQU-409)
It lasts for about 1 hr.
Can it be upgraded so that it last longer? Add more capacity/ cells etc?
And please state the price too.
Thanks!

Hi,
Can you please check if this model's battery can be done too?
1. Sony Vaio PCG-691P (Battery model PCGA-BP2V)
2. Fujitsu Lifebook T4220
Sony battery K.O. already. The laptop won't work if it's not connected to the DC power supply and the Fujitsu one last for only 30-45 mins even when the capacity is written as 5400mAh...

Quote me the price for both (increase the capacity/cell numbers).
Btw, can you provide receipt?

Tell me how to proceed with the repair too. I'll post the batteries (the BenQ one that I asked earlier, and the sony and fujitsu one too, if you can do it). I'll do it by poslaju, so tell me the total amount I need to pay. Thanks.

I'm glad I didn't go for the overpriced original battery, not to mention that they only have black colour while my laptop is white.
The battery last up to 3 hours during normal usage (wireless internet surfing with WMP playing and microsoft word open).
It lasts about slightly more than 3.5 if I just use microsoft office, which is really nice for a student.
I don't have to hunt for power outlets when doing discussions anymore.
My father was also very happy with the battery too. He wasn't very keen on 'realt-ing' but he changed his mind straightaway after he get back the battery since he didn't have to carry the AC cable even when giving out a 2 hours lecture with LCD hooked up to it.

Very good service too! I didn't wait long at all. Posted on Thursday, he got it on Friday, and even when he said it'll take some time since he got some batteries to work on, he had posted it back to me by Monday and I got it on Tuesday.

Thank you so much!!
