Lead Acid Cell vs. Button Cell

Lead acid cells were invented in 1859 by the French Physicist Gaston Plante, and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg, but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries, their ability to supply high surge currents means that the cells maintain a large power-to-weight ratio. This makes them highly desirable for use in large appliances such as motor vehicles, which require the high current provided by this type of battery.

In comparison, Button cells are much smaller than lead acid cells. …show more content…
This is reflected in the property of these batteries being able to release large surges of energy. As these are designed for long use and provide large power, the cost for these are quite high, ranging from $100 to $300 each. In comparison, the button cell battery is used for very small applications such as wrist watches and hearing aids. This is reflected in their small, convenience, and ability to provide a long lasting, steady flow of energy. However, this means that they are unable to supply large amounts of energy at a time, and are therefore unfit for use in industry and larger appliances such as motor vehicles. The cost of these batteries is much cheaper than that of the large, lead acid batteries, rarely coming up to above a few dollars. Impact on Society Batteries have had a large impact on society since their invention. In particular, lead acid batteries were among the first to be invented. These batteries have had a major impact on society; They have allowed for the powering of motor vehicles, which have become a major component in the lives of many living in developed cities. Though an older model of battery, these batteries continue to hold significant impact on society even today. In comparison, button cells power small, handheld portable appliances such as watches and hearing aids. This is asignificant difference from the impact of lead acid batteries.
