not sure why AGM battery is in this discussion.

we aint living in extreme weather and the pony 1.3 ~ 1.5L engine need AGM?

which expert brings that up

That I am not sure also if that is possible. I just service a client's Myvi early this month, never imagined that the Myvi had so many indicators in its dash. Kejap when I come across the video again on EFB batteries and the number of electrical loads that it has to support is really mind blowing, will share it with you.

Well I guess one could look at it this way, to hell with the vehicle's warranty, since this car will be on the 2nd hand market, so yeah. Your money, your ride, who are we to comment betul ? I have not personally checked with my friends in SC how much would it costs to replace a faulty ASA system if the fault was due to an incompatible battery use.

I know a damaged infotainment due to battery replacement can set me back by a minimum of Rm150 quote from P2 SC directly, not Authorized SC. Maximum amount I don't even want to know. Profit from battery sale, also not enough cover minimum damages to infotainment. 😨😨😨

What I do know is, the more electrical sensors it has, the more sensitive they are. Cars these days are getting more and more complicated. This is just 12V system. Wait till those EV vehicle become mainstream, those batteries dunno how many volts ? If kena dunno can die onot ?

One thing i have noticed is that there are more and more cars coming in with electrical problems at the mekanik bawah pokok operation. What does that tell us ?

He just stated, but doesnt conclude anything lah..

The main draw will still be engine starting. Efb battery allows heavy repeated drawing of current before have a chance to get charged. Esp during start stop traffic.

The sensors takes miliamps and should not affect much. Ecus have heavy filtering so voltage fluctuation would not affect it.

Infotainment damage is possibly from terbalik terminal. Likely shorted the polarity protection diode.

In any case, disabling the startstop should prolong the lifespan of the battery, efb or normal.

Ultimately is customer decision

Ev is another story. High voltage side is typically 600 to 800v. There is a DC DC converter that gives 12v for charging a conventional lead acid battery to power up the infotainment, fans, aircond compressor etc.

the pokok guud business fongshui

I would think so judging by the ever increasing number of people awaiting their services. There is a place business so good until many clients decides not to take their ride home. Dah jadi macam junkyard already. Don't know whether the mekanik managed to collect the payments or owners themselves decides to leave their cars permanently under the sifu custody all because of unresolved electrical problems.

If silap pasang I dont think only the infotainment will be the only problem, there will be bigger and more expensive problems.

OK here is what happened. 1st time I tested this Myvi Gen3, I immediately told to owner not to use the vehicle anymore, until I had done the battery replacement. It was a Bad Cell status. Since they have another car, use that first.

The following day, the owner drove to Jusco, no issues. On their way home, a strange 2" bar appeared across the screen. The owner immediately came to see me and showed me the bar. I also damn stupid, never whipped out the phone to record the damn bar. Panic sial, owner also sad already, saying really sakit hati stuff, like dunno this brand can trust onot. Told the owner no worries, go back first and will drop by an hour later.

Dropped by and we went on a test drive. This time armed with the stupid phone to record the strange bar for my HQ and my contacts at Perodua SC. KNN this time the bar never appeared again, until today. I had done a couple of battery replacements for this Myvi G3 but nothing quite like this ever happened before.

Since that incident, now I am very fussy about calls asking for battery assistance. If owners dont listen to their SC and wants my assistance in time of their need, I will usually give some stupid excuse. Surely got some other hidden problems brewing already.

Clients who allows me to do diagnostic test before their battery dies, then I know what exactly I am dealing with and I will be to help. Out of the blue new clients, I just send them back into the blue aje lah. Orang lain pun mahu untung ma.

Definately sounds snobbish but hey at least I dont have to incur any stupid repair bills later and most importantly loss of goodwill towards my Principal Co. batteries and me.

yes
myvi gen 3 only the 1.3L 2 lowest variant doesn't come with it
the rest of the lineup came with it

for me, i can accept CVT...nothing wrong with it
but i can't accept 3 pot...so right now, myvi is left that is still worthy to buy
once myvi changed to 1.0L 3 pot turbocharged, it's no longer worthy anymore

Sorry bro., what is pot ?

In some videos, there are some who are complaining about strange noises coming from the CVT. They are saying the 4AT is better. I don't la, thats what they claim only. Not interested to find out in detail.

Battery that suppork auto start stop is expensive...

Cylinder.
If me 1.0 3 cylinder masi ok la, if 1.5 3 cylinder a no no

don't really know the difference between AGM and EFB because i don't use it
but to say we don't live in extreme weather, that's wrong
there's a reason why our battery only lasted an average of 1.5-2 years

furthermore, u do notice EFB battery only given a warranty of 12 months while conventional battery give warranty of 18 months

3 pot is conventionally called 3 cylinder

Bad cell status is reported by the dashboard? Or your battery tester?
The 2"bar got give any obd code? Any check engine light?

Since u represent battery company, sure u have full range of efb agm right? The myvi case you replace with is efb as well?

Sorry to hijack this post for my curiosity

If disabled, then the battery should last longer right?

You have to understand the benefits of Start-stop (for the lack of uniformed word) other than the hippie-serving emission reduction. It can save your fuel. Many people do not know that the car system will not turn off your engine if the battery health is weak (depends on how good the sensor is from car to car).

There is no evidence or study that correlate start-stop with engine wear and tear as well, in fact it is quite the opposite.

Is the fuel saving justified by the price of the battery you have to change every so often?

First, every car varies. Second, the equipment in every car varies, so is the way the driver use them (some people love to blast the speakers really loud, add backseat monitors etc).

For this you have to get to know your requirement yourself, no one can accurately advise you.

And define change battery 'every so often'. I'm still on my factory-fitted AGM battery for years and the voltage is still good. If you change your normal MF battery every two years, then you shouldn't expect anything much more beyond that with your EFB.

Under warranty? No choice, let Perodua potong your leher.

Outside shop can get from RM230 to RM250.

disable auto start stop

use a NS60 battery, rm210 only

warranty 12mths

after 18mths just buy another new battery and sold off the used battery for rm30, sure got buyer
