Some of the benefits of our sealed solar batteries include: being completely maintenance free, sealed construction that eliminates periodic watering, corrosive acid fumes and spills, the design of these solar batteries also allows for a faster recharge and less than 2% per month stand loss means little deterioration during transport and storage. While any battery will be damaged by continual under- or overcharging, reducing its capacity and shortening its life, our gel cell solar batteries will accept a charge extremely well due to its low internal resistance. For any independent power home project, the perfect compliment and component would be a battery like our 8G27 Deka solar batteries. Call us at 1-800-810-9939 today!
