Engine Starting Battery

I think maintenance is more important that brand of batteries. Case in point my first set of batteries were Trojan's for both starting and house batteries. I dry camp 95% of the time and these batteries lasted 4 years. My next set were Sam's club for the house and Walmart for the chassis. These were almost half the cost of the Trojans. The chassis battery from Walmart lasted 9 years and the house batteries are 12 years old and still going strong. When I charge the house batteries I also charge the chassis battery. On my tow car I just let the alternator charge the battery and get about 4 years out of those. I chose Walmart for the chassis battery because there are Walmart's where ever I travel. Twice I replaced my Tow car battery when out of state in a Walmart parking lot. The newer ones have a 5 year warranty.
