Advantages of lead acid battery are more than disadvantages
Before I did this job, I had never known what lead acid battery was. But now, I know it is another kind of battery which is different from the common lithium ion battery that we often saw everywhere. Of course, they are also not the AA or AAA batteries that are always used in the flashlight, remote controller, etc. In fact, if you ever had a motorcycle, maybe you have seen these batteries. The motorcycle battery is one of lead acid battery. So do you know that?
Not like the lithium ion battery, lead acid batteries store electrical energy through a reversible chemical reaction. It uses a combination of lead plates or grids and an electrolyte consisting of a diluted sulphuric acid to convert electrical energy into potential chemical energy and back again. It changes from lead oxide when charged to lead sulfate when discharged.
The lead acid battery is simple and inexpensive to manufacture. There are many lead acid batteries manufacturers, OEM, such as Leoch Battery. Having been used over more than 140 years, lead acid batteries are reliable, mature secondary batteries, globally manufactured and therefore a widely understood technology. When used correctly, they are very durable and dependable. Their self-discharge rate is among the lowest of rechargeable battery systems. Capable of high discharge rates, the lead acid battery is able to deliver the bursts of energy that are required to start an engine.
Lead acid batteries are environmentally sound in that they are recycled at an incredibly high rate. Today, 98% of lead acid batteries are recycled. With low maintenance requirements, the lead acid battery includes no memory and no electrolyte to fill on the sealed version.
Of course, everything owns advantages meanwhile it also has disadvantages. The lead acid battery is no exception. But if the disadvantages are more than advantages, we can be sure they are not so useful, therefore we can give up even not use it. However, it turns out that they are useful for many years use in variety of areas.
The only disadvantage is that the lead acid battery cannot be stored in a discharged condition. With low energy density, poor weight-to-energy density limits its use to stationary and wheeled applications. They allow only a limited number of full discharge cycles — well suited for standby applications that require only occasional deep discharges. The electrolyte and the lead content can cause environmental damage, which is environmentally unfriendly. There are environmental concerns regarding spillage in case of an accident when transporting flooded lead acid. Thermal runaway can occur with improper charging.
