[....Putting back Amps. What I have notice is that chargers are able to put back minimal amount of amps only. I havent done any calculations on % yet but this is what I have observed only. As the battery is constantly being used, it slowly degrades with shedding, temperature etc. I suspect that it is the shedding of active paste from the lead grids is the major culprit. So over time the battery loses its capacity.
Very long reply eh...salute you for writing such a long reply with your handphone
I usually use my laptop unless I am outside.
First and foremost, the OBD2 I bought is cheap cheap only. RM 13 + RM 3 shipping. Initially bought for my Axia because ECU disabled (yes, disabled) my aircon for water temperature sensor problem (found out via OBD app).
Also it comes handy cause it displays at least an RPM meter , temperature gauge and other customisable gauge , something which my Axia (mine is type E, basic car) don't even have tachometer.
But I read one American forumer, managed to get details about alternator load even from Torque app. Damn.
BTW bro, you are mistaken about my "Smart Alternator" originating from Exora. Its from Axia eh
I think its nothing gotta do with regenerative braking haha. Not some micro hybrid alternator like Serena Hybrid or Mazda's i-ELoop.
I would say its because - when there is very little electrical demand, the alternator cuts out charging (not totally), that's why my volt meter shows a low 12.8V. That's why I mentioned , when braking - electrical demand increases due to brake lights, then alternator outputs more voltage .
I think your Myvi is able to do it too.
I haven't tried on my Exora, but I think it will more be difficult because it has more electronics. Will try it someday. Need to fully charge the battery then only can test.
Okay, about the charger amps. Yes, they usually output 5-6Amps , it may look small to you, but because its used to charge a battery without any electrical load, that's why it can efficiently charge a battery and supposedly better than depending on alternator for charging. Whereas alternator needs to do both - supply electrical demand and charge the battery at the same time. Again this is what I gather my research info from Mr Google.
But regarding about your comment about shedding is the killer of batteries, mostly say its due to sulfation build up due to undercharge. Also in order for you to know how much amps are put into the battery, you will need a clamp meter, to measure the output amps. Your battery tester cant do that.

True modern vehicles comes with too much electronics too some extent I will even say it is redundant and that unfortunately zaps a lot of juice from batteries as well. However there are various accounts of batteries lasting way more than 2 years too and that depends very much on the driver as well.
Myvi Advance + Eco Idle I've just replaced the stock Yuasa battery M42 EFB. It lasted 2 years & 6 months.
There's a forummer who claimed his Q85 EFB lasted 5 years. It is possible, just that you must know what you are doing. 😊
If that Myvi with Start Stop tech lasted for 2 1/2 yrs, thats already an achievement. I really wonder if the owner constantly/permanently disable the Eco Idle. Its pretty much just a gimmick to get extra 0.3 KM/L fuel savings, but at a cost of more expensive battery.
I've seen several times, Myvi / Bezza engine stopping automatically, when the driver wants to park their car .
I doubt this system is advance enough to detect steering position. I'm sorry - That's just plain stupid.
It is useful for long traffic light , but not for moving KL traffic jam, which stop for a while then move.This post has been edited by SleeplessEyes: Apr 30 2021, 06:49 PM
