Was told by toyota my battery reading 12.45v with 217cca. Said a bit weak. Do i need to change it now or can wait

yes, battery is a crucial part u don't want it fails when there is no mechanic nearby

Replace with hybrid battery more lasting

is this reading low in the first place

Normal

How long the battery use ?

ou 217cca is pretty normal reading. I dunno how to intereprete cca

wet battery toyota brand. 3 years i think

Different battery for different car has different capacity and also CCA (Cold Cranking Ampere). What is your car? Maybe someone here know the CCA requirement for your car?

toyota altis. I was told by toyota volatge is normal but cca a bit low

my car battery only last 1 year
the usual sealed century marathoner

better just change at SC,some car need to reprogrammed ecu after change battery

Get a new battery stanby.

It is time.

but the reading is not that low right

That is because old fashioned workshop are used to traditional car with no gadget or electronics. Nowadays, the workshop will connect other battery first before disconnect, removing and replacing old battery. This was not setting in the car would be lost.

Cca low depend the original battery. All car has minimum cca requirement, else car cannot start.

I usually DIY charge since battery voltage still ok.

What kok car is that ?

Never heard of ECU need reprogram.

if volt low but cca ok. Thats confusing right

That is because old fashioned workshop are used to traditional car with no gadget or electronics. Nowadays, the workshop will connect other battery first before disconnect, removing and replacing old battery. This was not setting in the car would be lost.

That's why I ask you to get a new battery to stanby la.

Not ask you to change.

During morning cold crank up, your battery voltage will be lower.

ok lagi...

unless nominal volt dropped below 12v and lower than 180ccA

When it dies, it dies
Then again, mine was a proton, lasted more than 3years

Century last slightly more than a year.

All maintenance free battery.

I am using conventional car battery brand name "YUASA". Use it since Sep 2012 and still using it now.

i see. My normal multimeter at home can measure cca? I know volage can

3 years already. Dont be cheapskate and go change it. I use mine max 2 years.

Nope.. its normal voltage high but cca low due to electronics these day. Thats why I charge not change battery

worth it to charge batteries nowadays?

not all cars but mine need to reset ecu once battery is cut out more than 5min. Car suzuki swift, car will jerk when slowing down at traffic light, low rpm below 600.

I would not worry much about CCA. It is the Cold Cranking Amp, the max current when you start your car in cold climate. We live in tropical country which is not considered col, even for Cameron Highland, I would say. The CCA is measure when the car is cranked at sub-freezing temp after the car is left at -18C for 24 hours!

If you have no problem starting your car, then don't bother. Once you familiar with your car sound during starting, you will notice if the battery is getting weak and need to have it check or changed. For me, I just make sure I have a good jumper cable just in case I need help. So, far, I have use it once or twice but not for me but to help other people

Change it but remember to take back the old battery...* maybe the voltage abit low because the key was on during the check?

Yes worth it. Buy charger and do at home before battery fail. No need to remove battery so no need reprogramming.
Peace of mind knowing the battery wont fail anytime soon is precious.
ROI after 2 times charge only

so the cca measurement sure not accurate la. My car send in service within 40 mins they gave me reading d. So means its barely 40 mins since engine offed.
I have multimeter at home what can i fo with it to check

bro got small one ke.

Err.. you start your car at normal temperature. So cca is stil valid except those figure has to be at some temp point to compare with other manufacturer. Low cca cant start car

Got.. mine use ctek mxs

Low cca, if daily car, not much problem.
But if 1 week you no drive, for sure cant start that

Healthy battery is min 12.6 V , measured after left overnite full charge.

After you install back the battery, drive the car longer to let the ECU learn back and adjust the timing. Drive few time and it will back to normal.

Even a 17yrs old car that I remove the battery don't no how many time, don't have such thing "reprogram ECU".

longest dun drive is 2 days to 3. Should be fine ? Anyway this reading is after 40 mins of engine stopping. Valid ke

Not necessarily not accurate. The method is defined different by different standard and all of them basically like that. Anyhow, even with normal temperature, they can add climate factor to the measurement meter to simulate the cold condition. This is what I believe.

Normally in cold weather the battery can't provide sufficient current surge during cranking, but in Malaysia we do not have that condition. So, even if it is a bit low, it is not much of a problem. The multimeter is not the way to measure car battery (or any battery condition) so to speak. The weak battery can give 12V measurement without load but if a load is introduced, the voltage will drop instantly. The device the workshop use has power resistor load when measurement is taken. There are many method used to measure battery condition anyway but this is the most common one and most accurate.

Measure it morning before crank your car.

wait... mine hit to 10.x / 11.x only i change. can't recall.

11.8v is left 40%

10.v is totally gone

+1
yes time to change after 3 years.
if TS wan to wait for battery kong first also can.

Once the car started, the alternator takes charge. The alternator will provide the electricity need to the car and at the same time charge the battery. You can remove the battery once the engine run with no problem. Battery is only needed during start. I think the battery will be back to its initial condition after about 10 min driving, in general, if the battery is good.

how u manage to go so low haha. Thats just heroic

thing is if still can last 1 to 2years i wont change coz my next service will be few months time kan

The CCA is just reference measurement number to state the capability of the battery only

oh thanks!

hahaha.. i dorno i told the workshop let it go on until the battery is dead ill just give a call to change.. last battery change is through CARPUT.. i think can use century hotline / GP hotline as well if you want to change on spot.. Within an hour they will be at your home.

I don't think any car has ECU with program or setting lost if battery is removed. There's no way ECU has volatile memory

If you can, check your car battery and tell us the rated cca on the sticker. If rated 600 but now 200ish can consider change actually.
Btw, i do agree with the person that said invest in a car charger.

From what i know 12V when not charging. 14V when charging.

I'll check once i got my car back. I saw just now he showed me macam normal reading 250 or 260 but I'll reconfirm

Standard prg have. But many new car have a feature to learn your habit of driving. Adjust RPM timimg according to current engine condition.

But totally lost prg of ECU is bullshit.

It will reset the ECU when power lost. So when power back, sometime the timing run away. Cause the engine current condition is different from new.

You just need to drive like normal for sometime, and it will back to normal. ECU will learn back.

I change my own battery for don't no how many time. Sometime takeout battery to charge and never put back for few day. Or holiday, takeout the battery for few weeks. Don't have such ECU reprogram require.

Need la sohai.

Meaning u cant afford those cars yet.

You def < 20k

True storeyz.

Its continental cars noob.

Not like your cheapo japanis car. Wanna suka suka take out bat.

What kok car need ecu program everytime changed battery?
U over 20k,u tell me.

If u say to reset airbags or esp/abs indicator, acceptable. But ecu??? Seriously??

14.4-14.8 when float charge.

13.3-13.8 when standby.

12.5-12.8 norminal voltage.

11.8v and below - RIP.

Do not charge your battery over than 14.8v. Or drain your battery below 11.8v. Both will cause your battery RIP.

Lulz go gugle la noob. U think i am obliged to teach u? Tu la mentality /k. Ta tau expect ppl to suap.

Jelas sangat kebodohan yang terserlah di sini.
Please, stop posting.

Conti cars dont lose their settings. At most just erase fault codes due to low voltages.

Unless u crank that car with low battery voltage, and keep on cranking till ecu or your navi gateways decided to fry on you.

Thats why i'm running a voltage stabilizer, because my car is running 1980s' style alternator that has no additional electronics.

Let me guess.
You are one of those driving contis, more than 20k salary. Believe everything u read on car forums.

This must change one set, that will require reprogramming if u do xxx to it, every x kms must change this, must change that despite conditions...

Confirmed!

I drive a conti and I have never heard of a car needing reprogramming

They say la... They say....
Reprogramming =better fc, power, etc etc...
They say la...

Which is total bullcock to me.

After crank up your engine, use a multimeter to check your alternator voltage. If it not in the 14.4v - 14.8v range, time to change the alternator.

But sometime below that voltage is cause by too many electronic thing install that running. You have to judge yourself.

Simple search on internet.

Dah lah katak. Pakai maibi viva kancil mestila otak kecut iq 0. Still live in gua berapi era tu pun tak tau.

Did u know that the cars u cant afford, even to change headlights need to be programmed in the ecu these days? Of course u tak tau sebab u cant afford those cars mah.

Dahlah bodo tapi taknak accept the fact jugak.

Kecian.

True syoreyz.

Unless they are talking about aftermarket mods but that has nothing to do with the battery going flat whatsoever. The mods are done via a physical connection.

Read my reply above. Go do ur google search. 1 single search how many millions result come out.

Is this what you learnt from MIT?Did the private banker fund your studies?

I'm lucky i'm driving a freaking dinosaur. The only high tech gadget i have in my car is the voltage stabilizer & coil. So no worries for me. My cap ayam batteries last more than 3 years all the time.

Why u all so lazy ah?

Mentality like fuk also.

Merehsia maju jaya.

You bring to Toyota, they are more towards preventive maintenance. So, anything that is starting to go off, they suggest to replace.

Did you read?
Technically that is not actually reprogram, it just resetting the ecu to read the new battery.

Tulah.... Tulah.. Kan dah kata bodoh tu simpan sikit.....
Do u even know whats an ECU in the first place?
The tered you showed are to reprogram the bmw battery control unit(not the damn ECU) that u have put in a new battery.

If u upgrade from a 90ah to a 100ah and above, u need it. Especially if you fukken drive a first batch F10.

If you are using the exact same model battery, you don't even have to reprogram @recalibrate the batt control unit. For fuk sake!

And there are bugs in the first batch, thats why they were requested to go back and update the BCM. Not ECU.

GODDAMMIT!

then what is the use of forums if we can just google the answer ourselves?
forums function to help others to find answers to our problems that might not be able to solved normally or we are not too technical to solve it.

Use until koyak

Nowadays a lot of deliver and install services

Apa takut

Once a battery died on me while I was driving. It was a very "exciting" experience.

Also, deliver and install service cost more.

What a waste of oxygen

Depends on their location usually FOC

Outskirt like Nilai, KLIA no choice

I think toyota 24h free kah. I remember my fren punya came to house free

Oh, which service? I know Century but I think they charge even though nearby.

My battery always died during morning crank.

Where got service that early. Rushing for work.

Either change to spare battery or use another car to jump start. Than change it lunch time or after work.

U wanna stranded at somewhere without mechanic? 3 years is long. Do yourself and us a favor, just replace it where we dun wan to see u open tered said battery died.

Some people think the ECU controls every electronic/computerised part of the car.

ECU =/= CAN

My Proton has CAN, and it doesn't require resetting. Some European junks do. Yet dumb owners are so proud of their unreliable junk. Always breakdown and cause jam. Celaka.

lel...bodo sikit2 dah la...malu je...

itu bukan ECU...itu registration battery mah (mAh)...if change battery to different mah..only if..

ECU will never need reprograming...learn la what is ECU...talk cock sing song...

paling kuat ECU reset if no battery power at all...ECU reset also no problem...what was lost is only certain parameter, like throttle sensitivity, ignition timing/ping, all those close loop setting, or gear change pattern (this is TCU not ECU)..



jangan la fast n furious sangat...
nampak orang cucuk OBD nak baca fault code mesti lu ingat nak setting engine racing kan?




how can it died, 'while' driving?
alternator kong?

So u telling me no need to reprogram the ecu ( register the bat) in the ecu and just plug and play? Dunno u childish or not. This is the biggest joke i have heard coming from a guy who konon knows about cars. Did u read properly i wonder?

I summarize for u can or not? Car, battery flat. Buy same model, will not start. Why? Because need to register in ecu. Old models like e9x e6x maybe can start but u try do that on fxx series? Biggest joker. Of course u dunno la and i forgive u cox u dont have one mah and u can crap whatever u want.

links to the charger you bought?

Oh so u wanna say u just go dashboard adjust adjust battery mah then can start already ah? Maybe can work on old models u try do that on new model see see. Also the settings in dashboard is a seperate from ecu one mah? Then where do u register battery? Write a few lines with marker pen on battery then can start already ah? Pandai oh. Boleh jadi mekanik la ni.

Oops. That was another case, a more serious problem. No fuel was getting to the engine.





Sorry ah.

Errr... I think the biggest sohai is u.
I have been replacing batteries on flat cars. (yes, ur so called f series) and no special programming or resetting, or recalibrate needed.

Only some lemon units in that batches need to be recalibrated due to software issue.

If u saying that the battery needed to be register in ecu before start is enabled, then dafuq they put the emergency (+) infront for you to jump start?? Since ur batttery dead, your ecu doesnt recognize your external power source, u tell me.

Jgn la bodohhhhh.... Re-register is just to keep it running optimally which is normally not needed... Tolong la....

2 experience I encounter.

1) battery terminal loose out and driving time, car like jerking. Not sure got died down. I only solve the problem. Not driver.

2) drive half way, and some panel light acting strange. Later all power lost and engine off. This is alternator kong and drain the battery out.

On some contis, they have this thing in the cluster.
"hey bro! Ur battery is dead! "
So u replaced a new battery, but your cluster doesnt know.
So u need to ERASE the fault codes from the car, now your car knows it. Alrighty bro, lets go!

There is a difference between ERASE, RECALIBRATE REPROGRAM.
even if this three is not done, your car will still start. Faham tak??

C'mon la. Some people might not know about your expensive BMW. When you replaced the battery the car will not start. True, but that is not re-program or register the battery. The car remembered that the previous battery was bad and does not know that the new battery has been installed because the old data is still registered in the ECU. You just need to reset or clear the data. It is designed that way to force you to go to BMW service center I suppose.

ECU comes per-programmed for main functions and can be re-programmed in SC. It is not end user accessible portion of memory. The other parameters from sensors that are transmission related go to TKU and the TKU provides input to the ECU.
