    I've just picked up a replacement battery for my laptop and I'm almost certain the new one will be fine but I'd like some confirmation.

    The original laptop battery is an AS07A31 while the replacement is for an AS07A32. The main difference is the original is 10.8 volts and the new one is 11.1 volts and I am hoping this slight difference will not cause any problems at all.

    Also, the Ahs are slightly higher with the replacement but I'm not concerned about that.

    So, nothing to worry about with the voltage difference?

    I have currently connected AC to charge the new battery with the machine off. With Li-ion batteries do you really need to drain and recharge them "3 to 5 cycles"?

    Thanks.

    The volts are less than 3% off. I've read 5% and often 10% is safe.
    The amps should be equal or higher - and there is *no* limit to how high, as the laptop only draws what current it needs.

    While the voltage difference is slight and that is good, the only problem I can maybe see is with the charger. What voltage is it rated at? If the battery's voltage is higher than the charger supplies, the battery will always be trying to keep on charging. This could put extra strain on the charger and charging circuits. Hopefully, the charger is rated at something like 12V or higher.

    Bill, the charger is rated at 19 volts, 4.74 amps so that shouldn't be a major concern.

    Thanks.
