Lead Acid Battery Disadvantages
• Low energy density - poor weight-to-energy ratio limits use to stationary and wheeled applications.
• Cannot be stored in a discharged condition - the cell voltage should never drop below 2.10V.
• Allows only a limited number of full discharge cycles - well suited for standby applications that require only occasional deep discharges.
• Lead content and electrolyte make the battery environmentally unfriendly.
• Transportation restrictions on flooded lead acid - there are environmental concerns regarding spillage. Thermal runaway can occur with improper charging.
