What are the disadvantages of a lead-acid battery?
It is also well known that lead-acid batteries have low energy density and short cycle life, and are toxic due to the use of sulfuric acid and are potentially environmentally hazardous. These disadvantages imply some limitations to this type of battery.
What is a lead-acid battery?
The lead-acid battery is the oldest and most widely used rechargeable electrochemical device in automobile, uninterrupted power supply (UPS), and backup systems for telecom and many other applications. Such a device operates through chemical reactions involving lead dioxide (cathode electrode), lead (anode electrode), and sulfuric acid .
Do lead acid batteries lose water?
The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
