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.
