A lead acid battery system may cost hundreds or thousands of dollars less than a similarly-sized lithium-ion setup - lithium-ion batteries currently cost anywhere from $5,000 to $15,000 including installation, and this range can go higher or lower depending on the size of system you need.
When choosing between a lithium-ion battery like Eco Tree Lithium’s LiFePO4 batteries and a lead acid battery, most users are looking to upgrade from their traditional lead-acid batteries. Today, the debate of lead-acid vs lithium-ion is somewhat redundant, as lithium-ion batteries are generally considered the better option.
Lead Acid Batteries Lead-acid batteries consist of lead dioxide (PbO2) and sponge lead (Pb) plates submerged in a sulfuric acid electrolyte. The electrochemical reactions between these materials generate electrical energy.
Lithium-ion batteries are 55% lighter than lead batteries, with a 3 KWh lithium battery weighing about 6 kg. They also have a greater energy density, which means they don’t need the same physical space as conventional lead-acid batteries. Therefore, lithium-ion technology is a better option if you want a lightweight and compact battery solution.
Lead-acid batteries are significantly heavier than their lithium-ion counterparts, which can be a disadvantage in applications where weight is a critical factor. Their bulkiness can also limit their use in portable devices. The cycle life of lead-acid batteries is considerably shorter, typically ranging from 300 to 1,500 cycles.
Lead-acid batteries consist of lead dioxide (PbO2) and sponge lead (Pb) plates submerged in a sulfuric acid electrolyte. The electrochemical reactions between these materials generate electrical energy. This technology has been in use for over a century, making it one of the most established battery technologies available.
