Lead Acid vs. Lithium Solar Batteries: Which Is Best?

Lead acid batteries are cheaper upfront and reliable for stationary use, but have a shorter lifespan and lower usable capacity, requiring more frequent replacements. Lithium batteries, despite higher initial costs, offer greater efficiency, longevity, and a higher depth of discharge, making them cost-effective over time. They’re lighter and more compact, suitable for those prioritising long-term savings and space efficiency. The choice depends on budget, space availability, and long-term cost considerations: lithium is better for efficiency and space, while lead acid suits limited budgets and larger installations.
