Compatible Laptop Battery

[hitman]

It depends on the maker also .. A very cheap battery is obviously a risk .. But something from reputed buyer from ebay is fine .. I have used compatible battery for compaq also and its been 7-8 months now.. and is still working fine ..
Btw I am currently getting 5hrs backup on this 12 cell battery .. and previous one (the 6 cell one) was almost dead .. It was just giving 15-20mins backup and sometimes was shutting down even before running out ..

----------

always a risky thing. i would have gone for the Dell's official battery if they had a 9 cell unit available. sadly they do not have 9 cell batteries for all their models.

not going to buy anything dell

Sony is one step ahead .. They have done something with BIOS which won't let u use compatible battery .. So u have to make some changes in BIOS to use compatible battery .. and availability of their original batteries in market is very rare and also very expensive .. The original 6cell battery 4400mah was around 11k.. and there was no 9 cell battery available ..

Well if Sony is one step ahead, these battery manufacturers are one step ahead from Sony too. Whenever you buy battery for such Sony laptops having such protection, they also come with a CD which has a patch to bypass this protection. I've seen it myself.

Why bigger mAH with more cell batteries are not manufactured and supplied by companies itself..I dont understand. Atleast we can avoid risk by paying more.

Exactly .. So we r basically left with no option except to go for these compatible ones ..@androidfreak .. Even I also got some cd along with the battery .. It tweaked the BIOS so tht compatible batteries can work ..

Woah 11k is quite steep... I recently got a quote of 8.5k for my MacBook pro battery from istore & I thought that was quite steep... But then again as far as I know MacBook pro' battery are quite good(7hr backup) so maybe that price is justified... I was only thinking of replacing my battery coz I am getting approx 3hrs of backup(which I thought was too low) & I was getting my trackpad replaced under bestbuy warranty & was trying to get them to cover my battery as well ... Anyway I guess the battery still has a year or so left in it...

Apple macbooks now have non user replaceable batteries. so they can put in customized batteries inside which are larger in size and makes more efficient use of the available space. user replaceable batteries do not offer that functionality as you have to fit them in a space that is accessible to the user which waste space and is not very efficient. a couple of PC makers are also now adopting a similar strategies. and there are laptops available in the market that offer good battery life (Windows) but Apple surely is ahead of the competition and is likely to remain like that for a while.

Owing a macbook pro...and my battery is user replacable....infact 2 days back I took out my battery to diagnose some problem ...

you have a model that is likely to be 3 years old. i have the last macbook that came with replaceable battery. and even after 3.5 years the backup is close to 3-4 hours. and it is a machine that has been literally abused wrt charging and discharging several times on a daily basis.

Even my old Powerbook G4's battery is user replaceable. I guess its only the battery of Macbook Air that is non user replaceable.EDIT: Googled a bit. The 2011 Macbooks have non user replaceable battery.
