Secondary Batteries (Rechargeable batteries) play an important role in our lives and many daily chores would be unthinkable without the ability to recharge an empty battery. In this regard, there are different types of secondary batteries that vary in their specific energy, life, load characteristics, safety, price, self-discharge, maintenance requirements, and disposal. These different types of secondary batteries have been explained below:
Batteries come in various shapes, sizes & types. They are normally distinguished by chemistry, voltage, size, specific energy (capacity), specific power, (delivery of power) and more. A battery can operate as a single cell to power a cellular phone, or be connected in series to deliver several hundred volts to serve a UPS (uninterrupted power supply system) and the electric power train of a vehicle. Some batteries have high capacity but cannot deliver much power, while a starter battery has a relatively low capacity but can crank the engine with 300 Amps. » Read more..
Invented by the French physician Gaston Planté in 1859, lead acid batteries were the first rechargeable batteries for commercial use. In spite of the fact that it is one of the oldest types of batteries, lead acid batteries continue to be in wide use today, for various reasons. Lead acid batteries are very dependable and much cheaper with respect to the cost-per-watt. Very few types of batteries can deliver bulk power as cheaply as lead acid batteries, and this makes the battery cost-effective for auto-mobiles, uninterrupted power supplies (UPS), golf cars, and forklifts.
