There are multiple battery types to consider when choosing solar batteries. Which type is best varies based on your needs and whether you prioritize cost efficiency, safety or environmental impact.
Deep-cycle battery
The term “deep cycle” refers to the battery’s ability to complete a discharge-recharge cycle several times. Deep-cycle batteries are designed to keep a steady flow of power over an extended period. Thick lead plates help prolong the battery's life.
Lithium-ion, flooded and
gel batteries are types of deep-cycle batteries.
Lithium-ion battery
Lithium-ion batteries are an excellent choice because they are relatively low maintenance and easy to install. The benefits of a lithium-ion solar battery include higher energy density, less weight and increased life span. Lithium-ion batteries are considered a revolution in home energy storage solutions. Brands like EverExceed use the Lithium Iron phosphate (LFP) which is the safest and most reliable among the rest of the Lithium-ion technologies.
Lithium-polymer battery
Similar to lithium-ion, lithium-polymer batteries are more resistant to issues like overcharge or electrolyte leakage. They are also more expensive and don't usually last for as many cycles as lithium-ion batteries.
Flooded lead-acid battery
Also known as wet-cycle batteries,
flooded lead-acid batteries contain liquid in an open container and disperse hydrogen gas. These batteries are cheaper but require more maintenance because the battery must be kept upright and well-ventilated. The battery also needs to be monitored and regularly refilled with distilled water. EverExceed
Tubular OPzS is excellent example of flooded Lead-acid batteries.
Valve regulated lead-acid (VRLA) battery
This valve-regulated battery is considered the maintenance-free option in sealed lead-acid (SLA) batteries. They are designed to keep the battery from reaching its gas-generating limit while charging, which prevents water depletion and gas dispersal. This also means that the battery can never be completely charged. EverExceed
Deep cycle AGM range,
Modular Max range are excellent example of VRLA batteries for your solar applications.
Solar gel battery
A gel battery, or gel cell, is similar to a sealed lead-acid battery. This battery also uses a gel electrolyte. Unlike other lead-acid batteries, you don't need to keep it upright — it handles movement very well, which makes it a smart choice for campers, vans and boats. Also the high temperature performance and better cycle life makes these batteries superior than the AGM batteries. EverExceed
Solar gel range,
Modular gel range is very cost efficient and great performers in deep cycle applications.
Nickel-cadmium battery
Ni-cad batteries have a long lifespan if properly maintained. This is one of the more rugged battery types available, but they occasionally require a full discharge to keep their longevity. Be aware that cadmium is toxic, so this battery cannot be disposed of in landfills.
