Lithium-ion batteries offer a longer lifespan, lasting 2000 to 5000 cycles, compared to lead-acid batteries, which typically last up to 1000 cycles. They also handle deeper discharges—up to 85%—without. . A lead acid battery is a kind of rechargeable battery that stores electrical energy by using chemical reactions between lead, water, and sulfuric acid. Solar power generation is erratic by nature; the sun doesn't shine 24/7, and weather inconsistencies affect output.
