    I'm looking for a replacement battery for my MX8738. The battery is labeled "6MSBG" and 11.1 V @ 4800 mAh. I am finding some 6MSBG batteries with that same number, same ratings, no problem.

    But - I am finding batteries that are also labeled 6MSBG, and are said to be compatible, but which are 14.8 V @ 6600 mAh (12 cells). They're advertised as having much longer life, and that's why I'm replacing the old one (short usage time before needing recharge).

    Now, from what I remember about electronics, you can increase battery wattage (current), but if you increase Voltage, things tend to go "pop" and let the magic smoke get out. :)

    Is a 14.8 V battery really an acceptable replacement for the 11.1 V battery the laptop came with? Is it worth double the money to get longer battery life?

    Any advice about purchasing a replacement laptop battery will be greatly appreciated. Thanks!
