battery sizes? is 440CCA too big?

[skiddz]

hi guys,

i bought a battery from the wreckers and its 440 cca, went to hook her up, i touched the terminal and she sparked a bit and then started smoking and teh wires got really hot ! i threw (even the 4ga going to the amps!)the old battery (305CCA) back in (just for a little bit of current while working on the electrics) got most of it working.

then i got an elcheapo charger attempted to charge the old battery and it acutally lost voltage (has 7 volts) and now NOTHING works, have i broken stuff? and can i use the 440 cca battery? and is 7 volts too little for stuff to work?

oh its in my ta22

"yup, theres yar problem righty there sonny..."

secondly, the fact that she made your wires get hot is about your car - not the battery. short cicuit somewhere. as for 7v - did you check it before installing? was it charged?

inspect the battery guts - are the plates collapsed, is the water topped up? specific gravity?

not that it matters anyway - buy a new battery, and sort out the short circuit in the car

hmmm i dont think i have a short cos before i changes batteries everythin worked fine, the old battery got 7v after i charged it so the charger is going back today and im gonna bite the bullet and get a new one

thanks ed

MORE CCA the better................

^^ What he said. I have a 600CCA bad ass mf in my TX5

i think mine is 520cca in my ke70 luke
yep, from the wreckers. been in there nigh on 2 years now. nothing wrong with $20 wrecker batteries
i think i know what you did...check the battery for the whole positive and negative terminals.
some of them are a bit inbred and are what would appear the wrong way round. i did the same thing in my parts car back when it used to go.
makes smoke pour out of all sorts of things lol

my JZMA70 has a 780CCA battery.

doesnt make any difference to how the car should perform, just makes it crank longer.

you've hooked it up the wrong way around dude, and by the sounds of it, melted some of the insulation on the loom.

reverse polarity FTL!

ok well i swaped to my other dash loom now everything is fine ecept the tacho and the wipers. the wipers i cannot work out why they arent workin..... ive run new wires directly to the wiper motor from the switch still doesnt work, i have even hooked em up direct to the power that works but bypasses the switch.

this is fucked

Hey there mate,
As everybody has said, the more CCA the better...

as for the wiring, u have defently melted some as well as it should have blowen some fuse's mainly the big ones under the bonnet eg. 100v Alternator

hope this helps

CCA stands for cold cranking amps. It is the amount of current the voltage can supply at 0 degrees farenheight. So the higher the better. A battery is a voltage source, meaning it places its voltage across the circuit (12V) and the circuit draws from the battery the current. The current drawn depends on the circuit and not the battery. So yeh... drawing too much current is because of something wrong in the circuit, not the battery.

i know what CCA stands for..... i am dumb but im not an idiot

and AFIAK i only have one set of fuses in my kick panel but i will have a look, i did blow one fues and im pretty sure i melted some of the old dash loom, hence my changing it, gonna run a new tacho wire and see where that gets me.... might also stop and think with the wipers for a bit...

thanks for your help guys

electrical smoke is only a factory feature of english-made vehicles ... with vehicles manufactured outside of the United Kingdom, smoke or melted insultation is considered a fault in urgent need of attention... it is unrelated to the output rating of the battery.

[skiddz]

yeah it only happened with the 440cca battery i bought a new one today its the same as the old one 305 cca and she goes alright, im gonna check the alternator and a few other bits n peices might go down to just toyota and pull a loom or 2 and ill score some more wire for my dwindleing car wire bucket

I wasnt questioning ur intelligence mate, i was just saying cos everyone seemed to just say bigger cca was better and no one really gave an explanation

[love ke70]

you SHOULD be questioning his intelligence
