Errm I had no idea what brand of the battery is.. but I believe before I change the battery, they got show me a list of different battery that fit different model of the perodua car. But I will check again and take a picture of the battery.

There is only 2 types of battery that are generally in use by Perodua which are NS40ZL and EFB-M42.

If there is another battery type that is in use in the new facelift Myvi is NS40 or EFB-XXX which the (+)ve terminal is located on the right, if I am not mistaken. I do not know what is the new code that is attached to this new battery yet.

Did you take a picture of this list of different battery that fit into different Perodua models ? Really interested to see what this list is all about.

Yes please take a clear picture of the top of the battery case with any wordings or markings clearly. If can't just type of those wordings. TQVM.

EFB is better suited to be in the engine bay area. Not the AGM battery, unless really good proper insulation is done to protect the battery cells.

How much did you pay for EFB-M42 battery in 2021 ?

OK. I double-checked the battery replacement receipts I received from Perodua Service Branch:

Date Part/No Item Amount
27/07/2021 28800-BZ340 Battery (Yuasa) RM493.50
30/04/2019 28800-BZ170 Battery (Yuasa) RM559.20

The 2021 replacement appears to be significantly less expensive than yours.

The interval was 2 years, 2 months, and 27 days excluding the end date.

So, I will expect to have the next battery change somewhere in April 2024.

Wow you have very good filing system. 👍

I think you have mistaken me for someone else. I do not own this Eco-Idle Myvi model.

Anyway, I am really surprise to see that battery prices has gone down in Perodua, whereas there has been a continous pressure to increase the battery prices in the market due to the weakening currency.

BTW, was the mileage recorded during those battery replacements ? If yes, do let me know. Do you use the Eco-Idle function or do you disengage it, immediately after the car has started ?

Date Part/No Item Amount Mileage
27/07/2021 28800-BZ340 Battery (Yuasa) RM493.50 111204
30/04/2019 28800-BZ170 Battery (Yuasa) RM559.20 70504

According to the info above, a distance of 40,700 kilometers between battery replacements.

After the most recent replacement in 2021, my Eco-Idle didn't work (to stop the engine) when I braked for a longer period of time. Maybe I need to retune the battery with the ECU to get it to function again, but that's not a big deal right now. Anyway, since I acquired the car, I've never turned off its feature, so I can watch its green Eco-Idle indication light up at a set speed range.

luckily ativa use wet battery type...

although my friend just recently change Myvi 1.5H battery and cost RM300 after discount.

Whoa ! Are you saying that after the battery replacement at Perodua Service Center, the Eco-Idle system failed to function ? How can that be ? Did you report this to the respective SC immediately ?

Yes, after I change the battery, my eco-idle didnt work too.. I am not sure why... I haven't get in contact with the peroduo service centre yet.

Yes, I have the same case with this guy.

Wait a minute, you wrote earlier that you would do your battery replacement outside correct ?

Anyway, if you had done your battery replacement in Perodua SC, this should not have happened. Did you bring this up immediately with the SC to resolve the mistake ?

Maybe at the next service, but it's not a big deal compared to the necessity to inspect my car's front suspension system.
