Solar batteries that are commonly used on solar energy systems. Each with their own advantages and disadvantages.
Flooded Lead Acid
Flooded batteries are the most cost efficient and the most used batteries in solar applications. These batteries are extremely well suited for renewable energy applications, and have the longest track record in solar systems. They usually have the the lowest cost per amp-hour. The solar batteries require regular maintenance and a good ventilated area.
Gel Electrolyte Sealed Lead Acid
Gel Electrolyte a Sealed Lead Acid battery the electrolyte solution consists of gel. This reducing the gasses, and volatility of the cells. They are not truly sealed and have a valve regulating gassing. AGM batteries are slowly busy phasing out the gel technology, allthough there still are many applications for the gel cells. The recharge voltage for Gel batteries are usually lower. Charging prefers a slower rate and avoid charging too fast. It will cause decreasing the capacity.
Sealed Absorbed Glass Mat (AGM)
Absorbed Glass Mat (AGM) is a valve-regulated lead acid battery the electrolyte is held in glass mats. The advantages of using this type of batteries are many. They are more expensive compare to Flooded Lead Acid batteries. AGM batteries can hold roughly one and a half times the amp hour capacity as the same amp hour flooded battery. This due to their higher power density. Their low internal resistance allows them to be charged and discharged much faster. AGM batteries function well in colder temperatures and are highly resistant.
