House batteries
Getting ready to go dry camping this weekend and my house batteries are not keeping 100% charge. I bought 2 interstate deepcell 06/2010 I thought I should get 4-6 years out of them but am told maybe 3 years.. So I guess my question is every 2-3 years I should replace my house batteries? my old cheap ones that came with the rv were 5 years old..

Three years seems about right Scott. My truck has two batteries (not deep cycle) and thats about when they needed to be replaced.
Scott, Are you using gel or glass Marine grade deep cell batteries? They should last longer than 2 to 3-years. Typically we get at least 5-years and have gotten up to 8-years on our boat which is kept in tidal waters and nearly the same on the RV's. We do disconnect the batteries when in storage and use a solar tender when in season due to the wonderful leaching appliances we love so dearly and can't live without. ;-)
Glass Marine Grade
Glass mat AGM need to be kept charged when stored and also need updated charger controllers. if you cant store with a plugin and have older inverter chargers, they prove to last only 3 years. Fiber Glass mats are just the medium they use to hold the acid. Deep cycle batteries like golfcart styles can be depleted and recharged better and are serviceable when you store in hot areas. We use our inverter and batteries often even for air conditioner and microwave. I have 7 years on wet cell deep cycles, with a ;smart charger, ;fulltime storage plugin, ;waterfill every 3 months. Battery Use is not the consuming factor for the life of batteries, Storage practice seems to be the factor. I want to replace our deep L16s with AGM Glass Mats but need to also update the inverter chargers and charger controllers. a small solar charger is also on my list. However, Tims list starts and ends Prevost.
