Hass VF2 says the battery is low .
Does anyone now where it is and can I can you change it yourself and is it
a standard battery or something made for haas
Thanks for your help Gary

[pit202]

from a time I have the same warning( TM`2004) , the problem is that the battery is at the lowest pcb plate , you can not reach the battery without taking all earlier pcs`s out

[metaler]

they should have used a battery holder with leads back to the board ,so the
battery could have been located of to the side and easy to change.
But then how could you sell the $29 dollar battery and a lot of service calls

... But then how could you sell the $29 dollar battery and a lot of service calls...

But if the only time you saw the Haas repair guy in 5 years was to replace a battery, who is complaining?

I haven't bothered to look for the battery yet but I know mine is coming due (4.5 years old). I got the impression that you could reach it while the machine was under power (so the settings wouldn't be lost) and could install their backup battery to a jumper connection. No?

[metaler]

I have not gone in there yet ,i got the battery with leads
Mine only lasted about 2.5 years , so if yours went over 4.5 thats good
they tell me I have to take out 2 boards and its on the bottom board,
plug the lead with battery in then cut old battery out.

i'll have to call my service tech - he didn't say anything about cutting out my old battery. I can see how it might be a problem unless they have a circuit to prevent drain on the new one.

HAAS ALARM 124 Low Battery

I just had this problem with my VF-6. Thanks for this thread I was able to locate the board with 2 batteries that is causing the alarm. Yes it's the last board on series of board you have to disconnect the boards on top to get to it. I called our HAAS local supplier and they told me that I have to replace the board because the batteries is soldered to the board. A replacement board cost $2,250.00. The Lithium Batteries are $6.00 a piece. Buy 4 so you can make a backup battery so you dont lose contuity.

Its no brainer. I have to attemp to do it myself. Even if I lost continuity to the board, I don't have to pay $2,250.00 for the board but pay a HAAS technician hourly rate to reload the software.

The important thing is to have power continuity going to the board so that you don't loose you parameter and software settings. Make sure you back up your parameter settings before attempting this. There is also an external battery connector that you can utilize to have a backup power running while you are replacing the batteries.

Just got done soldering the batteries to the board. Put it back together. My VF-6 is up and running. No memory loss..... :-)

I hope this help you all out there to not shell the money for a new board.

Update: You cannot load your parameters back if you experience a memory loss due to Alarm 124 ( Low Battery )

I was told by a HAAS technician that you cannot load your parameter, program & settings if you encountered a memory loss. Is this true? You have to call a Haas Technician to do it for you. I was told that their rate was $335 the first hour and $135.00 the succeeding hours....... Yes I was a little bit gung-ho about it but I think it was worth it. Just want to share this to all..........

Great timing for this tutorial. Mine just went out!

This is a great vid, except I would not do it with the machine on. You are just begging for something to go south. 200 Volts is nothing to mess with.
If you look at the 3.20 mark there is a white 3 or 4 pin connector to the right and just below the battery.
Haas sells (or you could make one) a battery with a pigtail soldered on.
You plug that in the white connector, go back the the original battery and check voltage with a meter. If you now have full (3.8ish?) volts THEN you can shut the machine off, flip the breaker and work safely.

Mine went out without the alarm Luckily I had just backed up everything) but it not as simple as reloading..I would say a good 6 hours on the phone getting everything backup and running. If you have any options..they all have options..
They will have to confirm your options, lead you to a page where you can type in a "code" to active them, THEN you are back up and running.

They will not just turn back on because you backed up the system. I now run an extra battery in the pigtail just in case I don't get an alarm in the future.

They told me the don't sell or loan the jumper part. Did you hear something different or have a part number to order?

32-1010 is the part number, but at $46 I am sure you could manage to make your own. Part Details | HaasParts.com

Same battery (no leads) : McMaster Carr 7821K63 for less than $6. McMaster-Carr

[Kool Parts]

Yep $46 smackers..and they took the money with a smile!
If I knew what I know now..I would just make one, but sometimes you just don't have time to source all of the parts.

Mine is low voltage but still working. Keeping the machine powered on until I get this sorted out.
I plan on replacing the battery like the video but would like to do it with the power off.
On that little white connector for a piggy back battery, does anyone know which of the 4 pins are + and -?
And where I might get a connector like that. Looks like a typical computer power connector?
Thanks,
Dan

[Kool Parts]

No help here as I just bought the one from Haas. But you are right it probably is a typical connector.
I have 2 both have the black wire from the battery in the top hole, the red in the bottom hole. Common sense says the red is positive..common sense..I wouldn't bet a cup of coffee on that though.
Gary

[KewlDan]

Thanks for the reply Gary!
I'm sure it would help a lot of people here (including me) if you could post a pic of it.
Also, is the black lead connected to the - side of the battery and the red to the + side?
Thanks again,
Dan

I bought the Haas kit that has the battery attached to the lead and then got 3 battery from digi key. Use the lead and one of the spare batterys. Now I got this stuff sitting on the shelf. I would pass it along for $35 delivered. If you want the Hass battery and lead and one battery to install let me know.

yes the red lead is the POS on the battery, A new battery from Digi key P/N P270-ND in package
