Old test meters for generator/voltage regulator diagnosing had the above as the "green range". In the day of relay type voltage regulators I bent the voltage regulating relay spring anchor for 14.0V (7.0V for 6V systems). I figured mid range would give adequate charge without 'boiling' the battery dry (lead-antimony then/lead-calcium now I think).

There are numerous threads about how the "New" voltage regulated alternators work. Apparently the automobile's ECM controls the output more than the Traditional voltage regulator does? If I had to change batteries that much I would be looking at changing the Alternator because I would assume it is the problem? Maybe your local Auto Parts store can run a charging diagnosis for you before going to the Dealer?
they still use lead antimony plates though they also contain silver and calcium.
14.8 can be a little high it should be around 14.1 to 14.3 although modern engines have temp compensating alternators and the voltage can vary according to temp as the way a battery receives charge changes with temp.
2 years is standard fair for a battery in a modern car. my suggestion is get a yuasa brand battery they are one of the best in the world optima spiral cell and deka are good too. and fit the physically biggest one you can
and take your car to a auto-electrician and have the charging and electrical system checked properly a volt meter tells you very little.
also make sure any accessories are wired correctly which is to wire them through the accessories circuit so they actually do turn off when you turn off the ignition. many people have caused them selves grief by not wiring correctly especially with these modern computer controlled everything cars we have today. also the charging systems are not designed to have accessories fitted they are just enough for the vehicle as it came from factory with a slight allowance if a higher output aftermarket alternator is available have one fitted since car batteries are to start the vehicle only the charge system is to power the vehicle with the battery smoothing the output as required.
