hi there, need to clarify something. my yuasa battery went dead only after
13 months, was surprised as previous other brands can last at least 2 yrs.
went to check alternator,all ok. mech told me my old batt might hv less
plates inside, sort of imitation one. was shocked to find out the weight
differnce compare to the new one. is this true? mean i got cheated last
year? my old one was changed by outside 'don't know who' mech, who came to
'rescue' when my battery mati at parking space.
as for jumper cable case, i bought a 200amp cable, personally never use
before, but i lent to a passerby when his car batt mati, he returned the
cable, very hot. after that, i keep till this case of my car batt mati,
then find out can't jump start already. is there a fuse of something
similar or 200amp is too low? just bought a new one 400amp, is it enough?
thanks in advance for any input.

I was advised to only buy jumper cable having the size of your little
finger and to forget about those tiny wires type. DIY using welding machine
cables is best.

I made myself a pair of jumper cable using 4AWG power cable.

My limited knowledge and experience told me that better or high amp cable
can jump start the car when the cable is connect.

Smaller or low amp cable need to wait about few minutes for charging the
empty battery then baru can start the car.

Correct me if wrong.

Correct me if I am wrong because I am never any good with electricity.

Let me put it this way: You wanted to fill a swimming pool with water. You
can use a small garden hose or a really big hose. Which would you go for?

Likewise, if you want transfer current, you can use a tiny wire or a thick
one.

guys,
the smaller cable will generate more heat as high amp passing.worse the
wire will melt and possible to burn yr car.eg, yr tv cables are much
smaller compared to yr iron cables as the iron requires more current.
my advice,dont buy the cheapo one...

a good set of jumper cables are a necessity. The cheaper sets will have
thinner cables which can not carry enough amperage to start some stalled
cars

Better check the cables carefully before buying- nowadays lots of cheapo
jumper cables only have thick insulation but thin wires, which can't carry
enough current to start engines.

hi all, my issue on jumper cable is that my old one 200amp is not
conducting ANY current! is there a 'fuse' issue here? and how come no one
comment on the 'light' battery case? is it really the case or the mech just
simply want to charge me for a new batt.
