They are the best battery you can get, you can mount them sideways or upside down if you want. They also have a shelf life of 12-15 years, when you discharge them completely you don't damage the battery. They are also spill-proof and 15x more vibration resistant. Also the biggest point of all is that all of their redtop batteires have a 36 month warranty. You really can't go wrong, i bought mine about 5 years ago and have never had a problem since.
http://www.optimabatteries.comHow often should you change out a car battery is it every 3 or 5 years?batteries don't need to be changed regularly. best bet is to load test it when you service the engine. And also check the voltage output from your alternator. It should be between 12.8-13.8 v.How often should you change out a car battery is it every 3 or 5 years?There is no definite time period on a battery exchange . Too many factors control the life of a battery . All you can do is watch it . I have had one last as long as 6 years and as short as 6 months .How often should you change out a car battery is it every 3 or 5 years?there is no set time just always do a charging system test and keep the cables and clamps clean and free of corrosion a weak charging system or excess load on the system like huge power amps or off road lights take a toll on a batteryMost batteries are stamped with the life span. Now whether they last the full stamped life is doubtful. Id say change it every 4 years, 3 if you live in an extreme climate. There is also something to be said for the quality of the battery you buy and the life span.it all depends on the climate, its the opposite of what you would think, if you live in hotter climates, you will need to change much more often, every 3 years to be safe, if you live in colder climates, you can go for up to 6 years, but thats pushin it.
