Daewoo Battery, Should I buy again?

[hasankhurshid29]

Assalam o Alaikum

I bought DRS 65 in 28 Nov 2018. https://daewoobattery.com/autoportfolio/drs-65/
It was serving me well except some terminal corrosion. I drove my civic 2000 infrequently. And in these 2 years the car has only done around 4k kms.
Yesterday when I tried to start the car after a rest of 10 days, it wasn't cranking. My scanner was showing 9V. So I jump start and drove it for 15 minutes. Today it also started without any issue. But the volts after turning on ignition (fuel pump and blower continuously running with ignition on) drops from 12.6V to 11.9V in few seconds and then stays there. But it started without any issue.
I think the battery life is over.
One more thing I notice was when it was discharged and at 9V, still the battery indicator was showing green and not white.
And this same battery will cost me 7000 and if I exchange it with current one, it will cost me 5200.
So should I go for it?

I would recommend ags wet one. Never used daewoo although I dont have good experience with dry ones.

I am using Daewoo since nov 2018 and driven my wagonR 50k after installing it. I am completely satisfied car starts on first self even in Islamabad winters now a days.

Wa Alaikum Salam.

I myself have been using Daewoo dry battery a.k.a. maintenance free battery in one of my ex-rides, however, was not quite satisfied with it, and its not that dependable.

I would suggest to go for traditional / classical type battery, which is old school type, i.e. Concentrated Sulphuric Acid + Water, and then charged fully, and preferably from AGS.

For long life of battery, ensure that distilled water and Sulphuric Acid are 100% pure, and may be, lab. grade.

Either battery is past its effective service life, or, there is something wrong with your voltmeter / multi meter.

So should I go for it?

If not satisfied with current battery, then have it replaced with AGS.

It served me without any issue for 2 years. Can other batteries exceed this?

That's the problem. Will have to check the water level frequently and then need to add water after every few days

I have checked it using my obd scanner not voltmeter. So its pretty accurate. I just started my car today morning. And the volts were 11.62 constant and it started without any issue.

[anon35615524]

YES. Provided they are taken good care of, and my above 02 cents (or 02 paisas ) are taken in to consideration.

[anon35615524]

If battery voltage is 10~11 Volts, then it may crank / start the engine, however, it'll not be considered a healthy battery.

For voltage between 9~10 volts or further below, then the battery may even fail to start the engine, especially in cold weather and winters.

[anon35615524]

As per my ltd. knowledge; Voltage across terminals when battery has been fully charged and car's engine is in OFF condition, must be somewhere in-between 12.5~13 Volts, or even more.

When battery is being charged via alternator / generator, the voltage across terminals is usually around ~13.5 Volts and above.

Still worth going for it!

Now the days it is taking to discharge is drcreasing gradually. Now at 7th day the battey has no juice the crank the engine. Also checked parasitic drain test and there is no drain when car is turned off. So means battery is going. Now you said that other batteries can run for more than 2 years whereas my father is saying that the other maintainence required battery like ags and excide are worst than this. They even failed at 6 months to one year previously. Daewoo batteey (DRS 65) is costing around 7600. And in our corolla se saloon its also reaching 2 years mark this august and have no issues so far and that car is regularly driven whereas this car is driven once a week mostly or even after 10 days. One bad thing is battery indicator showing green whereas it should be on replace.

battery will end up earlier if you use a car weekly or even less, then a car which is daily driven.

[margallar]

i think the battery may last another year if it is charged properly

yes get another daewoo battery

voltage will come in normal range after charging

[nfssaad]

use a daewoo. i have same in my civic. no issues.

[saadarmani]

I completely agree i had similar issue with Daewoo i have switched back to AGS

[hasankhurshid29]

Can ags give more than 2 years easily???

[saadarmani]

I have used AGS and maintained it for 3.2 Years main thing is proper maintenance

[hasankhurshid29]

Sorry to say but the main issue is regular maintenance. Pani checking is very difficult for me. And 3.2 years is not a good life. I think in daily driven car InshaAllah daewoo will give more than that. So i think daewoo is better option. The car I am talking is driven very less.
