Eco idle blinking after battery replacement

[abubakaryear8]

I have 2011 Daihatsu Move custom G. Its front battery suddenly died on me, or maybe i wasn't taking a look at it. When the battery got replaced, its fuel consumption increased by 6 kmpl, eco idle is constantly blinking even after driving a lot. What is the problem? Is it the ecu or the battery or do i need different battery if yes then recommend. Before it was working completely fine.
Both of the batteries are dry cell. I forgot the specs of old battery. If anyone is using eco idle, share the picture of your battery. I couldn't find the eco idle battery in the car. I have heard that the alternator charges the battery quickly that is why it doesn't have eco idle battery.

similar ECO/IDLE issues were resolved by installing main battery having high amperage.

there is chance that Eco Idle battery also have been depleted, u can check that as well to make sure the health and condition

Yes @xenerking is right. The battery is not the right one. The eco idle light is flashing 'cause the computer has sensed that this battery is not strong enough to support the load of repeated starts of this type of engine. Hence the eco idle function has been disabled which is notified by the blinking light. The eco idle function is there to give greater fiel economy. Now that this function has been disabled obviously there is an impact on the fuel average. Best way forward is to refit the exact same battery that was initially fitted to the car. I had this same issue with my son's 2014 toyota passo. Problem was solved by getting the right battery intended for eco idle cars.

On a side note. The 2014 Passo only has one battery and I sold it in 2016. So don't have battery details. We now have a 2019 passo. I will share pic of that ones battery.

I got this battery for my 2015 passo and eco idle works perfectly
