Jumper cable amp rating

[alfonsomiguel]

Sirs, ask ko lang. Critical ba yung amp rating ng mga battery booster cables? Sa 2.0Li na engine ano dapat rating?

TIA.

In my experience, YES. Lower AMP rated cables simply cannot carry enough current to crank-over the stalled car and just end up getting hot and may even melt through their insulation. But it does not really matter if the car is a 1.3 or 2.0L ....

Thanks alot Sir.

Most commercial jumper cables are 4 American wire gauge size do automotive use and will suffice for a 1.3 liter gas engine

So what's the ideal AMP rating to buy at the least?

Maybe 400 or 500 amp cables....

Also aside from the wires, check the quality of the clamps.

^Thanks.

I had one of those cheap 250 or 300amp ones before. It broke (the clamp in particular) after we tried jumpstarting my neighbor's Beetle. :D

On connecting jumpers:
1. Red (+) on the drained battery
2. Red (+) on the good battery
3. Black (-) on the good battery
4. Black (-) on a chassis/ground point on the car with the drained battery.

This is correct right?

Do note that the larger the engine displacement, the larger the cranking current. Also, Diesel engines, due to the nature of their design (higher compression ratio), will also have higher cranking current requirements compared to a similar-displacement gasoline engine.

Yup, and 4 to 1 when you remove the jumper cables.....

BTW, where is Master LSB?...

There is more to the story than jumper cables.... :naughty2:

vinj, this was discussed in the thread of C4U weeks ago. dapat daw (+) to (+) then (-) to (-). si uls yata nagsabi nun hehe

Amp rating should be 400A at the very least. Check also the gauge of the copper wire itself.

i used store-bought jumper cables to start a 10 wheeler truck (V10 diesel) ayaw mag start hehe

uminit lang yung cables

so we made our own jumpers using welding cable and heavy duty clamps

For our delivery trucks, we just swap the batteries to get it started. Store bought jumper cables doesn't help.

direct lahat, hinde na kailangan yun ground...I think ha...meron naman post for both + and - eh

My friends also used welding cable before when they relocated their batteries to the trunk.

I recall my dad's old BMW had a jumper cable terminal since the battery was at the rear.

It was something like this:

ya store-bought jumper cables are only for cars

mga trucks/heavy machines nakadisplay nadidiskarga ang battery so we put 2 4D batteries on a pushcart (naka-series 24V)

yan ang pang jumper namin

negative to negative works fine for me

same with me

[JohnM]

That's good. One less thing to forget Pero dapat positive muna bago negative then reverse to remove?
