Concorde Sun Xtender PVX-1080T Solar Battery AGM DEEP CYCLE 12 Volt 108 Ah

This battery is pricey but for the money you get a maintenance free, worry free quality energy source. I had one at my off grid cabin and the place was empty for 8 months a year. Came back and flicked on the lights and checked the battery - fully charged and ready to work. No issues for 5 years which is great. My other deep cycle lead acids were low on water and slightly discharged during the same time frame.
