I got the CCA meter and the my BOSCH S4 630A EN measured 421CCA EN.
The battery is 2 years old. In use in a car 1 year, the other year it was hooked to CTEK MXS5 every 2 or 3 moths for charging.
So is the 630A a BOSCH marketing hype or 421A means 66% of juice left?
P.S. I still have not got the AH meter so not measured the capacity. The battery was recharged then discharged/recharged. Reading stayed the same no change whatsoever.
