Any1 Jumpstart before using cables?

[Neutralsg]

Can anyone recommend a good jumper booster and price? No need for another vehicle for a jump-start. Thanks.

Not many places sells such jumper booster. There should be some seller in SGCarmart. Just search in Marketplace of this forum or google jumpstart battery booster and you should be able to get some info. There's a shop at The Central #03-55 who sells this. Autobac also sells a few types of battery booster.

The thickness of the jumpstart cable directly affects the current rating.

 

Thicker cable = Lesser electrical resistance = Able to handle higher current.

 

Higher electrical resistance = Higher heat generated = Higher risk of cheap/thin jumpstart cables smouldering/melting on the wire insulation and clips.

 

quality of the cable also matters. At the end of the day, the quality of the copper (or alloy) used will determine the material resistivity and hence the overall electrical impedance.

If the cables are too thin, you will find some warm-ness on the cable and eventually will get burn. So it it good to get a thicker one.

Yesterday night my ride battery flat in Suntec City, due to the radiator fan blowing even after engine shut...but that was another matter.

 

Bought a 500amp booster cable from Carrefour @$14.90, then ask my OC's sister to come over to help.

 

Manage to start though both cars are using Amaron MF Batt 35mAh. Thereafter when for a few spins to charge up the battery then everything ok liao.

If the starter car engine off, it will require more power and drain the battery thus affect badly, so must start the car 1st then do jumping

I totally disagree that the good(starter) car battery will be badly affected. What kind of affect will it suffer?

 

In basic electrical theory, hooking up the two batteries in parallel, simple means that the good battery is providing the juice to the the weak car just for ONE time starting of the engine.

 

After the weak car has started, immediately disconnect the jump cables.

Both cars will not suffer any effect at all. There will not be any voltage or current spike that will cause damage to both cars.

 

Unless the weak car has engine problem, and needs multiple cranking to start the engine, in that situation it might drain out the good car battery after a few unsuccesful tries.

 

Its just to prevent more problems. Not that the good battery will die. But sometimes the good battery might not have been charged fully yet and if you do not start the first car first, you might have problems starting the first car after starting the weak car.

 

Though on some cars the manufacturer recommends leaving hte good car off before starting the weak car as it might affect the electrical components in the good car. If your manual says that then just start the good car and rev for a few minutes before turning off the engine and starting the weak car.

Agreed with this. As some has mentioned, I used 2 cheap cables together and can jump start easily other cars easily. Can feel the heat on the wires too.

 

Since then, have added cables to my cheap jumpstart cables to increase the capacity.

my former car needed a jump start before.. i went to those diy shop and got a cable, and another car was kind enuff to help..

 

but when the connection was done, and we were trying to start my car.. the cable started to smoulder.. and i didnt wanna damage the other car, had to stop.

 

Eventually AA came and did the job. Until now i also dont know why. but AA guy said that the cable does plays a part. If it cannot handle the current, it will smoulder like what happened.

 

Thickness of the jump start cable plays a part. I once tried to jump start with a cheap cable. It didn't work and the cable felt hot. Went to Shell petrol kiosk bought a thick MIJ one and retried. It started easily and the cable is only slightly warm to touch.

Those petrol station selling $40+ jump start cable is the same as those I buy @ neighbourhood DIY shop below $20.

Cb petrol sell so expensive, such things still want chop us.

cable thickness plays a part.... kenna before after my friends car cannot jump start my car and felt the cable were turning warm....

 

Went Eng Wah Tyre and ask Vincent, which he confirm it does matter, in the end got myself a really thick one that works!!! : )

 

Cheers!!

You bought something unsure that it will work????

 

Must've been a good bargain

 

 

U r darn right. Very good bargain

Let's just say I buy thick ones below 10

I was unable to jumpstart my fathers car last week even though my car's battery is new.

The tow truck came and and we paid $30 for the jumpstart.

My fren say i kena chopped and introduced an app i think its called instacrank. 

Is this safe? anyone familiar and tried? http://instacrank.com/

Could it be due to the jumpstart cable not of the correct rating? If so, pls change it. If not, you will face same issue in future.

the Instacrank app seems like a good idea, but hasn't try it out yet. It will be very useful if help can be available faster. Once, I waited for 1hr for a mobile battery van when batt died. End up got a china made battery from them at an inflated price which became bloated in 6mth!

Yeah labour, fuel to get to the car park, tow truck depreciation, expenses... Etc. If not willing to let other make a living, then better buy one of those lithium battery jump starter with high ampere ratings.

Own self jump start also got danger. I know cases.of connecting the wrong connector. In the end ecu fried.

Of the person doesn't know difference between red and black and not willing to pay, then I would say he fully deserves it! 😄
