Look for HP laptops with secondary battery stretchmymind 4 yr. ago If tou want full day, i.e. Also, some apps designed for Intel or AMD laptops won't run on Qualcomm ones. Finally, a third way to get the same answer: Again, assuming the battery is 12 Volts, and is rated at 53Wh, we can say 53Wh 12V = 4.42 Amphours (Ah). As your laptop isn't going to draw energy at a faster rate when you swap the battery, it should last 1.73x as long running on the larger one. The watt-hour capacity of the battery depends on the number of cells. Many less-powerful and smaller notebooks can get away with batteries roughly half the size of the MacBook Pros and still deliver excellent results. The "battery amp hours chart" is a tool that allows users to calculate the amp hours of a battery bank. HOW ARE WATT HOURS CALCULATED? If not, go through this example: A 4400 mAh battery with ll.1volt means divide the rating mAh by 1000. Some companies just do a better job of making sure that this happens. This battery life calculator estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Does balls to the wall mean full speed ahead or full speed ahead and nosedive. Home | But there are still lots of variables that can make shopping for along-lasting laptopfrustrating.
