Myvi Gen3 owner here. The start/stop function will stop. Going to Perodua may incur service charge. Cheapest and easiest to re-enable the start/stop after changing the battery just remove the -ve terminal for 1 min and reconnect the terminal back to reset the ECU. Your radio, aircon, central-lock, driver window auto-up/down function will have to reset but its not difficult to do.

I recommend buying the same GS wet battery as from factory. Double the life than MF battery. Just check levels every 2 weeks and top up if necessary. Recommended seller:
