At this metal pipe. I don't see any other connecting points without paints.

I mean it managed to charge my car battery. I don't see any good raw metal without paint surface on my car.
I poked with my multimeter was sense some voltage through, thought it was okay

Well will do that, with a proper gauge cable I guess.
MrDIY one I feel abit questionable already.

Most likely will be a 1.5 years later I would need a near battery swap.

Buy a charger.

Charge the batts to 100% every 6 months.

Ur batts would last at least 3 years.

you left the engine idle start/stop feature always ON , or got turn off everytime you drive ?

i heard the feature will shorten the battery life.

Search 12V battery charger got a bunch.

Now price dropped till below RM50. Few years ago, RM80-110.

I got 2 questions seeking answers

1. Modern cars got so many electronic. Safe to jumpstart? Wouldn't fly the electronic?

2. Anyone use something like this to jumpstart?

Thanks to those people i found 1 month old battery at my friend's scrap yard.

U can try Kingbolen BM550, quite cheap and accurate, less than rm50 can get, youtube got ppl test it against Bosch battery tester and it is almost as accurate as the Bosch.

Redneck like me I don't just charge it using a conventional battery charger, I zap those battery with DC inverter welder, after zapping u can see the CCA improve. That how my scrap yard's friend lorry don't have to buy battery. And of course not all battery can be zapped, if u don't know what you are doing, you can end up with acid bath.
