Why is it that Amstron batteries have a higher capacity than OEM batteries, when they both have the same number of cells?
Each laptop battery is configured with a set number of cells to determine capacity and voltage. Each cell within the battery is configured to contain a certain Ah. The cells that Amstron uses contain 2.6 Ah / 2600mAh each versus most OEMs contain 2.2 ah to 2.4 Ah. Two-tenths does not seem very significant, but when configured inside the battery casing this small amount can add up to a ½ hour more battery life cycle. Each cell is connected in a parallel connection to create a maximum capacity, while the voltage remains constant. To read further about how cells are connected to create a set voltage and amperage, refer to our Serial & Parallel Connections Article. Not only will the Amstron battery last longer between charges, but the quality of the cells is comparable to those in an OEM. Amstron uses high quality cells that are produced by Samsung, Sanyo, and Panasonic to create a battery with optimal performance.
