Initial Cost Higher Lower
Lifetime Cost Generally lower Generally higher

Key Considerations

  • Lithium batteries offer better energy density and longer cycle life
  • Lead acid batteries are more cost-effective for short-term use
  • Consider maintenance requirements and environmental conditions
  • Factor in replacement costs over the system's lifetime
  • Consider space and weight constraints in your installation
