Function

• In general, the battery is an electrical storage device, housing materials that can charge, and stay charged, until the power is used completely. Some batteries can only be used once, while others can be recharged for use again.
  
  

Battery Facts

• The typical battery, such as for a flashlight, is composed of a centralized rod with a positive and negative end, and it is surrounded by a paste that has electrolytic properties. This paste allows electric current to flow through the battery to power a device.
  
  

Wet Cell Facts

• In contrast, a wet cell battery functions by using metal plates that react with a sulfuric and water solution. This wet solution is its electrolyte solution allowing electrical current to flow. These particular batteries have the ability to recharge, whereas a typical battery, unless specifically noted, cannot recharge.
