Electrical Drain Issue with CL Honda Accord

[oweis]

AOA Everyone,

I’m facing an issue with my recently purchased CL Accord. When the car ignition is off and I use the Android panel for some time, the car won't start without jumper cables — it needs power from another vehicle. Initially, I thought it was a battery issue, so I replaced the battery.
Recently, I went for tea at a roadside stall with the music on. After having tea, when I tried to start the car, it wouldn’t start again, and I needed help from another vehicle to jump-start it.
Can anyone help me understand what’s wrong? Someone suggested it could be the spark plugs and that I should change them ASAP. Any advice would be appreciated!

You're draining your battery. How long do you sit in the car with the engine off and what exact accessories do you use? If you listen to anything and use your speakers at decent volume, and have lights or fans on, you'll drain the battery even faster.

You already replaced the battery with a new one, so I'm assuming it is of the correct size, capacity and crank amps rating.

Next, if you're not sitting for too long, your alternator may not be charging your battery fully, so you end up killing it over a few days through cranking and using your accessories.

But if you're sitting for too long with accessories on, you'll drain any size battery and be unable to start your car.

You can test your battery's stage of charge and alternator functionality at home with a cheap simple voltmeter.

You might also have a parasitic draw issue, but since you're unable to start your car after using accessories for a while, instead of first thing in the morning, that's something to investigate afterwards.

Someone suggested it could be the spark plugs and that I should change them ASAP.

Utter nonsense. By that logic you should change your brakes and tires first to prevent your battery from running out while you're using it with the engine off.

Thanks for the detailed input. I’ve already replaced the battery with a new imported one, matching the correct size, capacity, and crank amps rating. But still, when I use the Android panel for just 5 to 10 minutes, it drains the battery so much that the car won’t start without a jump. Same thing happened when I was listening to music at a decent volume for a few minutes — and once when I was standing with the lights on for 5 to 10 minutes.
Also, when I checked the battery, the indicator shows green, which should mean it’s okay, right? Could there be another issue? Any advice?

If you're talking about the "magic eye" type indicator on the battery itself, it doesn't tell you much of anything that's relevant to the problem you're having.

A basic digital voltmeter is less than 1000 rupees at an electrical store. A healthy battery at rest (car hasn't been started for at least an hour) should be 12.6 volts. With the engine running, the battery terminals should measure at least 14 volts. Start there.

This is not good. Suggests a very high rate of discharge or a faulty charging system - imported or not, your battery is being slaughtered. It's not just the head unit you're using, your amplifiers are also powered on and using power if you're listening to music. If you're in the ignition position on the key switch, instead of the accessory (ACC) position, you have even more things turned on draining power.

Explain step by step what happens. You start the engine, drive to the tea shop, turn the engine off, play music for 10 minutes, and then the starter won't crank when you try to start it?

What position is your key in on the key switch?
Precisely what things inside the car are you using, e.g. AC blower fan, interior/exterior lights?
Do you have any external amplifiers or an aftermarket speaker system?
