Lead-acid solar batteries are a type of deep-cycle battery that is commonly used in solar energy systems. They are less expensive than lithium-ion batteries, but they have a shorter lifespan and take longer to recharge.
Lead-acid solar batteries are made up of lead plates that are submerged in a liquid electrolyte. When the battery is discharged, the lead plates react with the electrolyte to produce electricity. When the battery is recharged, the reverse reaction occurs.
Lead-acid solar batteries are a good option for solar energy systems that do not require a lot of power or that are not used very often. They are also a good option for budget-minded homeowners and businesses.
