My last Regular Flooded Century Battery NS40ZL in my workhorse lasted a cool 4 years, thanks to Lowyat expert forrumers, without them, my batteries wouldn't have passed 2 years. One must be extremely diligent in the care of the electrolyte. I was religously monitoring the electrolyte level every week.

The current new Regular Flooded Century Battery NS40ZL is 7 months now, hopefully with the same care, it will last another 3 years 5 months. After which, I instend to try out Maintenance Free Batteries which does not require religiously monitoring of electrolytes. Life too short. 😊

Thank you your sharing for it really did strike a chord. My latest ride coming to 3 years with mileage less than 7,000, I noticed that the CCA measurement is starting to go downhill despite using every trick. Peace of mind, now thats precious. 😊
Spot on. A battery must run the miles. I was doing Melaka-Muar-Melaka before I achieved 48 months.
