Charging Alternatives for 2x6V 10A Batteries in a Child's Toy Car: Your Experiences?

Question

Hello everyone, My first post so deep bows! I wanted to ask for help, because in electrical matters I am a festivity :) . As in the subject, I need advice on charging batteries in a 2x6V 10A powered car. The original charger is missing, so the question is, can I charge them differently? I...

I recommend charging the battery with the charger below because it has several advantages, namely it can be used to charge motorcycle batteries and then charging is at a lower current and after charging the charger automatically switches to charging with a small conservation current.

There can be one 12V. The car always pulls from both because the batteries have a common jumper and there is no separate cable for each battery. As a result, two 6V batteries connected in series with a jumper give 12V.

You can check.

Yes, you can safely connect. If the batteries are discharged too deep, this rectifier will not charge, because the electronics of this rectifier is powered from the batteries to which the rectifier is connected, then for a short time connect the other 12V rectifier to the batteries to increase the voltage on the batteries, and then connect this rectifier from the photo below.

This charger should do the trick. Just check the instructions with what current he charges, and then check the batteries with the maximum current written.
If the current is not too high, connect this charger to the batteries (disconnect the cables from the installation and connect to them, leave the jumper).
You can also charge separately (without a jumper), this rectifier can be seen that it has a 6V control, which means that it can also be used in this way.

By the way, gel batteries. If you over-discharge them, they are disposed of, or rather disposed of.

I understand that I have to connect the red rectifier cable to + in one battery, the black rectifier cable to - in the other, while leaving a jumper between + and both batteries - which can be seen in the first photo?

fotomh-s · Answer

Yes.
You can also separately, then you need to set the rectifier to 6V or something. If you charge with jumper 2 at the same time, then you must have the rectifier set to 12V.

If they do not charge, or the charger refuses to charge (it can detect that the charging current is too low) it will mean that the batteries were excessively discharged, then only replacing the batteries or playing with regeneration.

As in the picture.

fotomh-s · Answer

Will be OK.
According to the instructions http://www.manualsdir.com/manuals/828461/ultimate-speed-ulg-38-b1.html?page=16 this rectifier can charge with 0.8A current, so it won't be too big. Just set the first mode (6V) as you charge individually, or the second (motorcycle) as you double charge with the jumper. Do not set modes 3 and 4 because they have higher charging currents.

I connected both 1 battery and 2 with a jumper, but unfortunately the charger blinks with all LEDs, which means:

I think, however, that I'm going to buy new batteries ... Maybe a little bigger right away? Must be 2 or maybe one 12V?

fotomh-s · Answer

So they were over-discharged. To be sure, you can still check the voltage with a multimeter. If it is clearly lower than 6V (per battery) then the batteries are useless.

You can also try to charge one at a time, there is a chance (although rather small) that one is still to be saved.

PanSamochodziq · Answer

And what about buying new ones, I have to buy 2 x 6V or maybe one 12V. Anyway with larger A, let him ride longer ...?
Somewhere I saw the attention that if there is a 2-speed toy car (and this is it - slow and slow mode

), these are supposed to be 2 batteries, because in faster mode it pulls from both batteries. But of course this can be bullshit ... Photo of the cockpit below.

Thank you for your help! So something like the following can I safely disconnect from the alarm and check?

PanSamochodziq · Answer

It's ok - the car went !!!! Thank you. I have no idea about the power supply. Now there is the problem of controlling the RC with this toy car. Unfortunately, the radio that was next to the car is not from him. Do you know how to check which radio is right for you? Maybe you can choose something from other RC toys, and if not, at least buy the correct one. Added after 7 [minutes]: And if we connect 2 discharged 6v battery to this 12V (in series) and start charging .... I am a little fanciful, but will this rectifier with electronics not detect it? Because the power supply was 2x6v all night and nothing ...

Anonymous · Answer

A long time ago I came across such a car - in the first gear the power supply was 6V, in the second gear the batteries were connected in series and the power supply to the engines was 12V.

fotomh-s · Answer

But how can a 6V power supply be in first gear when there is a simple jumper on batteries? There are no separate cables from the batteries, but there is an ordinary jumper which with 2 batteries 6V makes practically one 12V ... The jumper constantly connects both batteries as seen in the pictures ... So how can a 6V power supply in first gear be used? The jumper will magically disappear?

kierbedz4 · Answer

Two 6V batteries connected by a bridge constitute a 12V on-board installation. If you deeply discharge the batteries while driving, the electronic rectifier may not start charging, then connect the second 12V power supply for a short period to increase the voltage on the above batteries, then connect the electronic rectifier and it will charge this battery set and after charging it automatically disconnects charging and switches to conservation charging with low current. Single charged batteries charged with 6V voltage and setting the charger to 6V range may also not start charging due to the fact that both batteries are deeply discharged.

fotomh-s · Answer

If they were deeply discharged, you won't even charge them with a laboratory power supply.
There are methods to bring them back to work. Some resuscitated gel batteries by adding distilled water. However, if it is sulphated, this method may not work.

The problem with gel batteries is that when you deeply discharge them, you have a problem. They are maintenance free as long as you make sure that they do not overcharge.

Once I wanted to bring back one such 12V battery, unfortunately no adding water or combining with voltage / current did not help. Generally, gel battery after deep discharge is useless.

In this case, the car is powered by 12V. In the car I was dealing with, the batteries were connected to the speed and direction switch - they did not have a fixed jumper / bridge.
