check your output on the regulator on the alternator may be higher than normal, but a battery should last more than a couple of years

Don't most batteries have a longer warranty period than 30 months.
I think the battery on my S class is about 4 years old and still in perfect working order

You need to check the charging voltage, should be around 14 volts with engine running, cheap own make/label batteries are hit and miss
