Time during which the battery is discharged by the hazard warning lights

Question

Hello, I have a Ford Mondeo. I have a 60Ah battery there and I have such a problem that the emergency lights turned on quickly (about 2 hours) discharged his battery. I would like to add that I listened to the radio, but the radio itself could play for a long time, even all night long and the...

Count yourself how much it should be. Suppose exaggeratedly that one bulb is 15w and there are six of them, and the radio was using 40w (also exaggerated). It gives us about 130W of consumption, i.e. about 11A, 60Ah: 11 gives us over 5 hours of battery operation. So the whole thing was definitely too short because the consumption was counted with a large margin on the plus.

but in fact, it was practically one night that the radio was playing and only on the second night I added emergency ones, although I think that the emergency ones flashed quite quickly, so maybe it also had some effect. I have just checked and it turns out that the directions are 21 W one bulb, so I think I already have an answer now 6 times, it gives about 120W plus the radio that was already playing all night and then another and these 2 hours, I mean that it is emergency together with the radio turned on and then it lasted these 2 hours because the radio itself was playing earlier. Thank you for the reply Ps. means, however, such emergency ones are not so economical for the battery and can discharge it quite quickly.

Yes, to be precise. The power of the direction indicator bulbs on the corners of the car is 21W, while in the 2 side indicators they are probably 5-10W.
The hazard lights come on periodically, so they consume 40-50% less energy than if they were lit continuously.
As for the radio, when it sounded with full power, that it was throwing the kennel (another thing when you can listen to something like that), it also milked the battery nicely then - almost like an emergency.

hello, assume that the emergency power is 90W, periodic operation 50% gives 45W + radios will be about 40W you have 85-90W in total, which gives about 7.5A, with 60Ah battery it gives from a fully charged battery max 7h, but if you give the burner with the radio, and 2h may not be enough, good luck

Count yourself how much the starter needs to start, because it will not even turn when undercharged. The battery must be at least half functional. What if it's diesel? it's more than half because it's 60.

yet the glow plugs which consume about 60A before starting for 10 seconds and when spinning the engine with 20: 1 compression, they do not go out either, the battery probably is not straight from the store, and charging with an alternator ensures topping up of max 90% capacity, the emergency ones work in a cycle of 50 50, but there are also losses when starting the 100w circuit. the radio may have an additional amplifier for the bass speaker. - unfortunately, there is no excess energy in diesel with such a small battery. Currently, to my surprise, in diesel vans /e.g.espace/ the alternator has 1000watt and is water cooled and the battery is 92 ah.

And for example, if I was bored, I would stick a lighter every 3 minutes, and every half an hour I would also start the starter for half a second, so you can calculate it for me? Ha, I rolled you out, every now and then I blink long ones, the frequency and time of switching on - how do I want ... People, please ...
PS How do you approach the subject so scientifically, how much does a given bulb with a hot filament take and how much "at the start"? Check this empirically, an interesting experience. Good luck.
Since when are alternators valid? It always seemed to me that the current "given" is the most important. If you got 1 kW, you still have a lot of excess, it will power everything up and the battery will be recharged. Because capacity has nothing to do with it.
