At the end of the day, it’s customer’s choice to vote with their wallet. It might be a bad move by p2.

I understand the theory behind it, but I suspect it is premature to be incorporated in a myvi.

Don't think premature is the right word, it's not like people change battery every year. Mass consumers want all the bells and whistles that conti cars have, they are not possible with conventional power source setup.

I am sorry, they are trained to follow certain procedures and they have to abide by it. If that means taking down your vehicle registration number entering into their stock system to check for parts availability and listed prices. That is how their computer system is programmed. If I am not mistaken other SC also operate the same way car number first. The worst was at a Honda dealership, I got my client car number and wanted to buy a certain spare part but they said I am not the owner. WTF ??? Maybe my Rm is valueless I think.

The 1st release of Myvi G3 ought to have passed 4 years. Starter Motor not yet kong yet like in my client's car.

How about fuel saving vs. cost of battery replacement?

Get Yuasa, the original batt in Myvi G3, 1st batch all made in Japan, now all in Thailand, shopee around 290. Best one to get is Yuasa.
Varta is from Korea but maintenance free.
Amaron is from India.

cheap

I am sorry, I don't own this model. So cannot comment on fuel saving.

I don't focus on the cost of an EFB battery alone but what I would focus on, is how to extend the life of the battery as much as possible, thereby reducing the costs of battery replacement in the long run. That is what I do for my clients.

Anyway fuel and battery costs are generally inversely related. Either you incur fuel and save on battery costs or incur higher battery costs and save on fuel. Take your pick. I am talking about good quality batteries, not some substandard batteries.

I am curious, what is your average battery life span ?
Is the average battery life span getting shorter and shorter over the years with each battery replacement ?

Update:

I just found out after they change the battery, my idle/stop is not working, going to call the service centre and ask about it

Hence my point:

For a very fuel-savvy car like myvi, does the fuel-saving gained from auto start stop outweigh the cost of EFB/AGM battery replacement?

If not, then p2 should reverse.

Car manufacturers are just thinking about marketing numbers when they introduced this auto start stop. Primarily petrol consumption and emission numbers.

But as a whole it's bad for the consumers and the environment. With the extra stress on the batteries, alternator and engines required it's actually a terrible feature to put into the car.

I was not referring to your point. What I meant is when one drives, the car will consume fuel but, at the same time that recharges the battery hence extending the battery life span.

However I do understand your point, unfortunately to even come close to such a real life data on fuel-saving gained from Stop-Start function against battery cost is a tough one, as too many variables are involved.

Why not just focus on trying to increase the EFB battery life span instead ?

Yea, that’s what I was thinking as well. Can’t really sell a car that’s just as good as the previous version. Must put something else, even if that something is a step back that is marketed as progress.

I don’t think recharging the battery extends the lifespan of the battery itself.

Unfortunately that’s a much a larger field outside of the scope of this tered which is myvi.

If it is AGM battery then for me rm500 is reasonable

Are you saying that when the alternator recharges the battery, it does not extends the battery life span ? Please explain maybe I did not get you properly.

I think many can vouch that putting the battery on an external charger itself already extends the battery life, though not many owners Myvi Gen3 did that yet, I presume.

No worries I got time for batteries and if you have any information on this larger field do share. I would love to go through them.

Charging and discharging a battery shorten the lifespan and lowering the charge capacity. Same thing with higher ambient temperature. This is true for all batteries including the one in your phone.

I think what you mean here is increasing the charge of a battery, not lifespan.

What battery brand is it? This Myvi 1.5 H model comes with an Eco Idle mode. Your price is less than what I paid in 2021 for a Yuasa start-stop battery.

If I'm not mistaken, Perodua claimed in 2016 that the Bezza Advance variant has regenerative braking. I'm curious why they chose EFB over AGM batteries.

Ah yes sorry. I dunno la but I am happy when my clients are happy that their battery lasts longer. Then got repeat order ma. 😁😁😁
