stay pluged in or not

I guess in America we all think differantly but the only time I plug mine in is to recharge the batteries. I realize that most batteries die due to sulfation but keeping them plugged in 24/7 means the battery plates are always shedding lead due to the electrical charge and the chemical reaction inside. I dry camp 99% of the time so I only recharge once I get home usually after a week and my batteries are about 50-60% SOC. If not camping I let them self discharge to 80% SOC then recharge. Over winter I fully charge in November and recharge in April. My house batteries are 14 years now and still working fine. I do equalize and desulfate several times a year which helps to extend battery life.
