Maruti Ciaz SHVS: Weak battery disables start-stop system

After 4 years and 10 months, the battery of my 2017 1.3 Diesel Alpha Hybrid seems to have become weak and the auto-start-stop light constantly flashes and the function does not work.

BHPian Foxbat recently shared this with other enthusiasts.

After 4 years and 10 months the battery of my 2017 1.3 Diesel Alpha Hybrid seems to have become weak and the auto-start-stop light constantly flashes and the function does not work. Apart from that everything is working as normal (car starts on the first try despite single digit temperatures).

Does it make sense to replace the battery now or wait some time? What are my options to replace the battery? should I get an exact replacement (same brand and models as it lasted almost 5 years).

Here's what BHPian jigar1791@gmail had to say on the matter:

Hi, I'm facing the same issue in my 2018 Petrol MT (facelifted version) since the last fortnight. Initially, I thought it's the usual rat menace with wiring going kaput, but a quick visit to our trusted FNG confirmed wiring is intact. Couldn't check on the battery health, since he didn't have a working battery health checkup machine.
All other parameters and functions are normal - audio/AC/1-shelf start etc. I also see the Hybrid Battery being charged when the car is in motion. All of these do point towards the OEM battery becoming weak, will still investigate more on this when I visit MASS over the weekend.
During my most recent periodic service in January '22, our SA did hint me on the OEM battery gradually becoming weak, and his battery checkup slip rated current health at 40%. Though I'm yet to confirm his suggestion, I think it's the battery that's causing the issue we're facing.
If that's so, it bothers me to know that the OEM battery lasted just over 3 years and 3 months, with the ODO reading at 27K!
Are we getting something wrong here, or that's the usual life of these conventional batteries, or the Hybrid setup somehow sucks more from the conventional battery to power itself?

Here's what BHPian foxbat had to say on the matter:

I got the battery replaced with the same exact model of Exide for Rs.7000 after exchange.
The original battery lasted about 4 years and 10 months and about 27,000 km before the start-stop feature stopped working. However mine was a Diesel not sure if the petrol has the same battery.
