Hi all

I have some V60 batteries tha we replaced based on timeframe rather that low performance.
I am wondering if anyone has any idea how I could charge them.
They have 6 wires
The main +ve and -ve
2 thin blue wires that have no voltage in relationship to the main power feeds.
then it has a Brown and Orange wire which both show a voltage between the +ve feed of 10.76 volts
and zero between the -ve

Define "how could". Do you know how to charge a battery or are you looking to charge this battery, but don't know how?

 

<irony> According to his post, I think he is interested how charging of batteries works in general. </irony>

Cant find info of the battery itself, if you search a schematic of the respiratory device that is part of you might get understanding of the purpose of all wires.
But I would hook up the thick black and red wires to a car battery charger to see what happens. Dont take my answer for granted if you dont feel comfortable.

I want to know how to charge this battery

I have tried charging direct to the red and black terminals but it does not accept a charge.

 

Welcome to AAC!

Is there any label on the battery that mentions voltage or "amp-hours" capacity?? In fact, are there any labels at all on the battery that contain any sort of information??

If those batteries are the same kind as in that attached picture, then the TS (you) could have told us that they were 14.4 volt 11 amp hour batteries. THAT is useful information, while "V60" tells me not one useful thing.
The correct charging method depends on the particular chemistry of the battery cells.

Why would I post a picture that was not of the battery I am talking about?
seriously

 

why is everyone drifting from what the TS was asking? his pictures contain all the info and his quest in the first post was absolutely clear this is happening a lot on this forum I dont understand why.

If you find some schematics of the respiratory device it belonged to, maybe some of the other wires need to be short-circuited, or receive some signal to enable the charging. Just guessing. I did a short google search to find the pinout of the battery but no luck.

 

Probably the red and black wires are for connection to the load, since the load probably requires more current while the charging needs to be controlled. Are there any markings on the PCB at the points of wire attachment? Sometimes boards have useful markings.
Does the TS have any access to any of those devices that the batteries came from?? OR even any information about them or how the assembled systems are recharged???

My answer to that is another question:
WHY SHOULD I NEED TO DIG THRU PICTURES of what the TS has already had plenty of time to examine before asking the questions????

 

Charger your battery with 1.5 amps overnight.

 

My suggestion is similar to post #11, except charge it at a lower current,about 550 milliamps. That is about five percent of the amp-hour rating.

 

So what is the point of having the option of posting a picture if people think it is too much trouble to look at it.
It is not like it is encrypted... so you have to dig through the picture... its right.. there.....

 

With my internet connection photos take a while to load at some times of the day. THAT is why.

 

here is a good article for you to read. https://www.digikey.com/en/articles/a-designer-guide-fast-lithium-ion-battery-charging

 

DE we even know what sort of batteries are involved?? are they NiCads, Lithium, lead/acid, or Ni/ Mh types??
It certainly looks like there may be a charger control circuit on that board in the photo. In fact, although they can't be read in the post, certainly if the TS has access to a magnifier they could be read, and possibly understood, and that could provide the clues as to how to power the device for charging.
In short, there is a lot of information available to the TS that we are not given. AND, that information can certainly assist in seeing what is required to charge the battery pack.

 

The picture says rechargeable Li.

 

The picture says rechargeable Li.

OK, It seems that I missed that part.
Now, we can guess that the attached PCB is the charging system, and that the heavy leads are for the load and at least two of the other leads must be the charging supply input. So there are two options: Discover what the notations on the PCB next to the wires tell us, OR trace out the circuit to discover which wires are the power supply input and which wires are control connections.
