If the 100-amp battery is weak, will the car start? If the car would n't have started with the old , weaker battery, do I have a better chance of starting with the stronger battery?
The same conditions apply to both batteries. Both are weak. Which one, with the remaining charge, is more likely to start the car?

Loading...Hello everyone, I recently bought a car. There are a few small things missing in the car. I wanted to ask where I can get them. I couldn't find anything on Amazon. They are small things like volume clips, something like that.
Hi, I have a question. The other driver I had an accident with swore that my driving license would be revoked. I fled the scene but stopped 150 meters away in the same parking lot and waited for the police. I actually wanted to apologize and ask him to call the police, but I can't…
Hello, I have error 17582 fuel metering system on my Golf 4. This error occurs sporadically but 95% of the time only when idling. I've read a lot of things but nobody has a solution for this error. I hope someone has had experience with it and can help me. The lambda value is 1.00…
In the yellow frame see picture It's a kind of holder…what's it called?
Hey :), I've been to quarter-mile races a few times in my life, and from a spectator's perspective, those races are simply amazing. 😀 I don't know about you, but I always feel really comfortable there and could watch all day :). But the last time I watched, a few questions popped into my head:…
So which type? is an Opel Omega B bj03
You’re confusing ampere with ampere lessons! That’s completely different. Whether a battery has 80 ampere hours or 100, does NOT say about the power of the battery. This is only the indication of the capacity.
With a 50L petrol tank, you can’t drive faster than with a 40L tank.
If you want to know how powerful a battery is, you need to pay attention to the maximum cold start current. That’s the ampere, that’s the power.
The battery capacity is often compared with a water tank, but one can only compare a certain property with it.
A larger car battery not only has more capacity, but also a higher cold current. A 100Ah battery therefore has more power than an 80 battery.
To compare two AGM batteries from VARTA 580 901 080 has 80Ah and 800A and the 605 901 095 has 105Ah and 950A.
The larger battery can actually bring more power than the smaller ones. Thus, your comparison with the gasoline tank goes down.
No, not necessarily. In the case of self-design yes, which is also logical somewhere, but that is not always given. An 80Ah AGM battery has a higher or at least similar cold start current than a 100Ah lead acid battery. Between manufacturers and model series, there are also large differences in the cold start current between batteries with their own capacity. It is therefore not possible to automatically close the cold start current from the capacitance.
Although this should be so in this case, my comparison is nevertheless justified, because the capacity in Ah now does not say anything about the performance. It is and remains the unit of capacity and nothing else.
Hello,
This question cannot be answered so simply, since, in addition to the question of structural identity, in particular in the case of batteries which have already been in use for a long time, their internal state in relation to plate wear, any sulfateation by excessively deep discharge/correct storage, acid level/acid level would be asked to do so.
Let us simply assume that the design would be physically identically constructed “lead-flowed” batteries, and the 100 Ah compared to the 80 Ah battery would then have only 20% more, or 20% larger lead plates, with otherwise identical construction with identical acid levels ( physically determined by acid lifters) and in each case identical rest voltage.
Then, the capacitively larger battery would have a residual current capacity of up to 20% higher under load at the same temperature only with identical wear and the degree of sulfation of the lead plates. (I still talk about “aged” batteries )
In the absolute discharge level limit range, and/or a determined low temperature level, this 20% capacitance/and load current difference could then definitely decide whether the available load current is sufficient for the first motor revolution (still) or whether it is no longer sufficient for this.

It is so that the 100 ampere battery when it is empty is not regenerated as fast as the residual current as the 80 ampere battery, but is basically stronger and lasts longer and so on.
I now reduce my opinion to a single answer on my question, because there are probably more specialist knowledge of what I cannot add now and what would blow the frame.
Perhaps it is also advantageous and the service life is still higher if you start the engine somehow differently and the battery stronger is recharged. The But maybe it’s not about starting behavior. (Owning regeneration of battery power)
The 100 battery has more reserves. That is why this can give more power.
Such a 12V lead battery consists of 6 cells. Each cell contains several positive and negative plates which are connected in parallel to one another. The 100’s battery has more such plates than an 80’s, this can release more juice. Even though both are equally weak.
nix of both, how much V do the batteries show? under 12 then you could have a problem with jumping
Apart from that, I’d be interested in what battery has better chances.
Not in the trap. you need to charge, whether 80 or 100A
The really correct answer that is true 😂
