I have run this type of battery in many aircraft over the years and have no problem getting 7 years average with most running 8-9. the thing that will kill this type of battery is overcharge (either by a charger or cars electrical system). I use a pulse on off maintainer milliamp type plugged in year round on the wet matt type batteries or gel cell. Have not used anything on the Camry yet. Most of your ATV and bikes, waterbikes ect are using this type of battery at this time. I think you will see the old complete wet type phased out soon as they cause so much corrossion and cannot be run upside down like then new ones can.
