I have an Acer Aspire 5536G. My battery is having problems so I am thinking of replacing it. I have searched online through many sites and I found some good deals. However, currently my laptop has a 4400mAh lithium ion battery so I was thinking of replacing it with 8800mAh 12-cell battery that lasts more hours than 4400mAh without power plug.
The mAh value is a measurement of a battery's capacity calculated from the average number of amps discharged multiplied by the number of hours it took to fully discharge. It represents the amount of current the battery could theoretically discharge in one hour. For example, a battery that can discharge 500 mA for four hours has a capacity of 2000 mAh.
The battery will only supply as much amperage as the device requires, so a higher mAh rating is not a problem (and indicates longer battery life). What matters here is that the voltage of the battery matches that of the computer.
Yes, its safe as long as its output voltage & current values are same. Output voltage has more importance.
