Laptop batteries are usually marketed in Watt-hours (Wh) for a few reasons:
Watt-hours provide a consistent measurement of energy capacity: Watt-hours are a measurement of energy capacity, which makes it easier for consumers to understand how much power they can expect from the battery.
Watt-hours help compare battery capacities: By using the same unit of measurement (Watt-hours), consumers can easily compare the battery capacities of different laptop models and brands.
Watt-hours can accurately reflect performance: Watt-hours can provide a more accurate representation of a battery’s performance compared to other measurements such as battery life, which can be affected by various factors such as screen brightness, power-hungry applications, etc.
Watt-hours can provide a baseline for battery replacement: By knowing the watt-hours of the original battery, consumers can easily determine if a replacement battery they are considering has a similar or higher capacity.
In conclusion, marketing laptop batteries in Watt-hours provides a consistent and reliable measurement of energy capacity, making it easier for consumers to understand, compare, and evaluate their options when it comes to battery life.
