Ultimate Speed Charger from Lidl: Compatibility with C330 Tractor Battery?

Hello
I have the ultimate speed charger from the lidl, can I use it to charge the battery from the c330 tractor?

Theoretically yes, but it will be a torture of 6V 165Ah, and here you have a maximum current of 3.8A, it will "take a while". Better find something more current-efficient.

You did not provide the current efficiency of this power supply as well as the battery capacity. Generally, you can only charge when the charger is "small" and the battery "large", the charging will take much longer. Obviously, the rectifier and battery voltages must be the same.

Uncle gooo ...
will answer .
The maximum charging current is 3.8 A, I do not know how much the battery from the tractor has, but probably about 120 Ah - i.e. the charging time is about 120 / 3.8 = 31 hours, but if it is not fully discharged, you can try it the next day start the tractor.

By default, the toilet 330 is equipped with a 12 V 165 Ah battery (2 batteries for 6 V). At a charging current of max. 3.8 Ah, the charging time of these batteries will reach 48 hours.
Although many users often find only one 12 V battery with a capacity of about 100 Ah (it has a single 12 V 98 Ah battery installed itself) - then the charging time will be much shorter.
Besides, if these are already quite old batteries, they can consume quite a significant idle current (2-3 A), which can make it almost impossible to charge such batteries.
To sum up - if they are relatively new / functional batteries, you will charge them somehow, although it will take quite a long time. However, if the batteries are old / heavily worn out, you may not be able to charge them.
However, you can connect a rectifier - at most charge the battery with a rectifier overnight, then start the tractor (if it works) and recharge the batteries with a generator / alternator.

You're kidding, the generator has 150 W of maximum power, which can be obtained at quite high engine revolutions
Well, unless it has an alternator, it can be done

Yes, you can, from the user manual of a similar charger, it was clear that charging the 80Ah battery takes 24 hours, in practice 170 Ah 12 V the battery was charged for about 3 days. The rectifier may have a security that after a day it stops charging (I assume that you have read the operating instructions). If the battery capacity exceeds the capacity supported by the charger, then it must be turned on again after a day.

There is nothing to worry about as the charging will take 72 hours, we do not know the algorithm that the processor of this rectifier drives

And the author's rectifier has about 50 W of maximum power. What is stronger? This rectifier or generator?
When he starts the tractor and works with it for a long time, he will recharge it with a generator (provided that he will not use the lights and start the engine frequently).

Rather, no field work comes into play
I have bad experiences with generators, I do not say that I will not recharge it, but it will take a while

And what voltage did you get on the generator?

I am not better - where I had power generators, the battery lasted only 2 seasons. After replacing it with an alternator with a battery, I have 5 years of peace and nothing indicates that the battery will end quickly.

And I'm not saying otherwise. But I know I can. This is what I had to do once, because it happened that the tractor was left at the traffic lights and the battery died completely. I recharged the battery overnight with a toddler charger (max 4 A). In the morning I managed to start the tractor - I worked it all day with a front loader (you know, it worked quite high) and, surprisingly, the generator was able to charge the battery.
For sure the alternator would do it much faster.

And what was I supposed to achieve? Not less than 13.8 V - increasing with charging.

I have never measured it exactly, for the c330 it is 400 rpm and the generator starts charging from 800 rpm after increasing the rpm, you would have to wait 10 minutes before the voltage reaches 13.8 V

Not 400, but 550 rpm.

Even if you had to wait these few minutes for the voltage to rise to 13.8 V, what is the meaning of it considering the fact that the tractor worked almost 9 hours almost continuously? When the engine was running continuously, the voltage remained at least 13.8 V even if the revs dropped. And it was work with a front loader, so all the time in the upper RPM range.
I wrote about the fact that if you work with the tractor for a long time without using the lights, you can recharge the battery in a drip, even with a generator - and I am talking about this in describing my own experience.

I have a question, what voltage should a fully charged c330 battery have on the terminals after a longer stop (e.g. overnight)?

A 6 V battery, when fully charged, should have a voltage of about 6.3 V.

And two 6v batteries connected in series 12.6V should I understand?

Yes exactly.

Mine has 12.2 volts. Is it possible to determine the degree of its charge from this?

My colleague, magnus27, instead of reading the manual for this rectifier, asks questions of the public. People show off elkwency not knowing the reality, i.e. what are the batteries in practice, and whether a tractor for generators or an alternator. After numerous observations in nature, it is difficult to ask about the technical condition of the machine.
So the answer can be of course yes. But you won't get any effect if you want to charge them in 10 minutes. And I often find that charging is needed immediately before starting. And the more you can charge your batteries with this charger throughout the night, since there is a suspicion of their poor condition. Oh. Colleagues are figuring out that there are two batteries there. This is true, but the voltage of both connected in series is important for vehicles, so I do not know if there is any point in exposing it. We will soon find out that this rectifier has burned down.

You can roughly say - this voltage means that the battery has about 50-60% of the charge in it.
