Will A Higher Mah Battery Last Longer. It will simply take a little longer to charge it. One Milliamp is one thousandth of one amp.
I have been asked a few times if its OK to use higher mAh rated batteries in your laptop. However your charger will take longer to recharge a higher capacity battery. When considering AA to D cell batteries AA batteries usually have the shortest mAH life while D cells have much greater mAH.
Its definitely got the ring of truth but theres way more to it than just mAh battery life.
For example a 4600mAh battery will last at least 45 hours. Its amps over time. 1 mAh means one milliamp delivered for one hour. As an added bonus the battery should also last longer because itll be less stressed since higher mAh also means its capable of delivering more amps.
