    I installed a new battery today in my Acer 5630 and it showed Maximum battery life 650%! I did have a 4000mAh before but bought a 4800mAh. This is 14.5v as opposed to 11.1v. Does something have to be reset for the increased power? It has been running an hour now and is down to 300%.

    What...

    You shouldn't use a 14.5v battery if the original is 11.1v for the notebook, that could damage your notebook!

    Agreed - this may cause irreparable harm to your notebook.

    That seems very strange, it should have the same voltage, not more not less. If the notebook isn't compatible with a higher voltage, but i hardly doubt that.

    Don't use the battery until you really know if it's safe. Or else you could damage the notebook!

    We have just spoken to Acer technical and they assure us 14.8v is completly 100% safe to use replacing the old 11.1v and they quote "The machine will only draw off the power it needs" This is the new higher cell battery.

    I must admit I was worried as you all seem to know what you are talking about there. I am still hesitant though but it has been fine for 3 hours now.

    That seems strange though.

    If you have 14.8v output the source will get 14.8v output and not 11v or anything else. So that it'll draw the power it needs, doesn't fit the voltage output, atleast not in my head :)

    Can you ask acer how that works? Does the notebook has any power regulators or such that can change the 14.8v to 11.1v?

    Did you buy the battery from acer. I would get some sort of assurance of them (in written or email form), just incase the battery causes damage to the system and they will cover the cost of repair!!!

    They said the machine will only draw the power it needs so it is regulated

    It is an Acer battery and the one they sell if you want more power they say I am covered if there is a problem, they checked all the details at length

    Useless post is useless. :rolleyes:

    To the OP: If you bought the battery from Acer you should be fine, but if you bought it from a 3rd party I'd try getting a different battery. It's very odd that the voltages are different.

    The battery is an Acer product obtained from a third party but checked out with Acer technical to whom I gave all the details (ie voltage and part number). I have now used it for a total of 15 hours on battery power and it is working fine. As a matter of interest how long would it normally take to burn out if it is wrong. I am still not 100% confident due to your comments.

    Just to let you know I have been running the laptop on the new battery since I last posted and it is fine. It runs for over 4 hours which is a massive improvement on the old one.

    Of course the voltage will increase the more cells you add into the circuit.

    Im guessing the 4000mah is 10cell and 4800mah is a hi cap 12 cell?

    Most notebooks can tolerate up to 19v for external super capacity batterys
