Check what the voltage is at the battery when the engine is running at >2k RPM.
Should be above 12.5 volts all the way up the ~14.3.
Use a volt meter or read it in the cluster.
My battery lasted 8 years. The battery in my wife's 01 Volvo is original and still working fine....knock on wood.
2000 540/6 Slightly tweeked...everywhere
