Stock Ke70 Battery Good Enough For 4age Conv. ??

[toyke70]

Hi All,

 

It's come to that stage where i need to buy a battery to check all the ECU wires are correct and need to know if a standard KE70 4KC battery is enough for the 4AGE ( Enough CCA) or do i need to buy a AE82 ( what my GE is out of) ???

 

 

Any help Appreciated,

 

 

Thanks all.

540cca works fine with an ae111 4age. Try something around that.

battery CCA usually relates More to Accessory's fitted to the vehicle eg Air cond, headlamps, demisters, sound systems ect more than it relates to cranking power needed to start.

when fitting a 4age the only main extra requirement is a ecu and electric fuel pump your current battery should be OK.

CCA stands for Cold Cranking Amps, and is directly related to starting the car, and what it will supply to crank the engine...it has nothing to do with what accessories you are running, and they are taken care of by the cars alternator....except when the car is off, and then they run directly off the battery, and that is when a batteries "Ah" is brought into play, as that is how many amps it will supply for "x" amount of hours before going flat....Deep cycle batteries are made to run things in this manor and go flat and be charged and go flat and be charged....Cranking batteries however are not made to be drained flat and re-charged all the time, and will wear out quickly if you do that to them. Cranking batteries didn't used to display an Ah rating, but new batteries these days quite often do, as they are a bit tougher when it comes to using them like a deep cycle battery.

 

A 4AGE will be no harder to start than any other 4Cyl engine with similar compression, but the higher cranking amps you get, the less the battery has to work to crank the engine over, and usually, the longer it will last.

Extra battery capacity is recommended if your vehicle has a lot of electrical accessories such as air conditioning, power windows, seats, electric rear defogger, etc. Manufacturers will recommend a larger battery for vehicles with lots of accessories. CCA would be about the same on any 4 cylinder. For any "regular" lead-acid battery with a CCA rating, just divide that CCA number by 20 and you'll have it's true Ah capacity.

yes but the accessories are still powered by the alternator when running. So unless you are running a significant amount of accessories while the car is off, around 350 cca should be plenty for a small 4

 

Most recently released small cars use around that figure, and they carry far more accessories today than say 20 years ago

Its not like you start the car with the aircon running, stezza playing, lights on, and gerge forman frying in the back seat. Get an uprated battery that fits in the old space and has the terminals in the correct places. If you go too big you are just wasting money. Too small, it wont last as long, even if it will start the car. To ke30 ke35 ke55, I have to agree with rollaboy. Accessories have nothing to do with it really, unless you go as far as a 4wd fanatic would, and fit car fridges, jacks, winches, airbags, spotlights and compressors etc. Then you would go to a dual battery setup.

yep^^ accessories have nothing to do with what size battery you need. the alternator puts out something like 50A at 12V, so when your driving along there is no way you are going to be able to draw more than 50A through ANYTHING in the car, my stereo with the 12 sub and a few speakers, at louder than i would ever user was at maximum 6A. headlights take a fair chunk if you have 2x60w globes going, thats 10A there, fan thing is no more than 5A.

 

so at maximum my car has under 20A at "normal" night driving.

 

pretty much just get a battery that fits on the battery tray, and you will be fine.

And if you want to be really safe, (and if you are rich) get an Odyssey battery, they have stupidly high CCA, and they will maintain 50% charge after sitting on a shelf for 2 years....

 

The largest size Odyssey battery is slightly smaller than your average Falcon/Commodore battery but we have had one hold 1100CCA, the same as the largest size truck battery that was sold at the battery shop I worked at.

 

 

But just use the battery that is in your car, and when it dies, and you have to buy a new one....you would be better off spending a little extra and getting one with a slightly higher CCA, that way you should be covered for a long time.

 

 

I have an AC Delco battery in my coupe, that I have had now for over 5 years, and twice in that time the car has sat for over 12 months, and once charged, it is STILL working. They come with a 3 year warranty, and for $140 that they retail for....is quite reasonable I think. You could spend $50, and buy one every year for 5 years....and clearly you'd have been better off buying the more expensive battery.

my odeyssey cost around $300, it should easily outlast a couple of normal batteries so it works out cheaper in the long run. plus its really small, weighs less, sits in the boot without needing a vent to atmo.

 

well worth it.

It definately will outlast 2 normal batteries. They can also be mounted any which way, the only way they can't be mounted is upside down, but sideways and on the ends is fine.

They also handle vibration better than most...We used to sell alot to Harley riders, because the vibrations from a harley killed normal batteries really quickly.

You got a real bargain there I love them because I hate rusty acidly battery trays.
