What is the average lifespan of 6v batteries? What would shorten the typical lifespan? Is there a big difference in longevity between the different types of 6v batteries? Thanks
OP here. I am a fulltimer, 99% plugged in to shore power. I have 4 6 batteries. Current bank is 3+ yes and need to be replaced. Just wondering if there is something I can do to increase longevity with the new ones? I use the profill system to keep water level topped off. Anything else? Best name brand?
