View Full Version : Changing a battery on a Haas display

01-30-2015, 11:49 AM
A 2011 year Haas display has been giving a battery alarm. We managed to succesfully replace the battery and now must reinstall firmware. All the information has been backed up on a USB drive. Any insight of what to do next would be greatly appreciated.

Call Haas and do it right.

You replace the battery while the machine is on so you don't need to do this.

Hopefully it is easier to restore than a fanuc...

There's a 3.6 volt battery on the board, it's lithium and on the older ones soldered, caution, the newer ones are plug and flying lead, there is a correct way to do it, that doesn't involve killing the bios chips etc, expensive to replace I found, impossible to replace on an old one as the nice people won't sell just the chips, they sell the whole board, which may or may not work, I found all that out the hard way, the old machine was unsupported, how nice, I ordered the battery from radio spares and thought a simple swap would be all it took, several thousands later the dam thing was never right, nothing but problems
Ended up tossing it in the scrap bin with a 30 ton fork truck
As has been said, call hassle as I call them, they may talk you through it on newer ones,

Mark, On what kind of mill?

I had to re input all the parameters on a Makino 1516 with an old Fanuc 15M. Not fun, it had the SRAM card that replaced the old bubble memory card. Still more fun than the Matsuura with a Mitsubishi control that had a battery we did not know about die. To install the final options we almost had to have a tech fly out to input the password so we could reinstall the options. Luckily a guy swore me to secrecy on how to do it and let me finish it. That's when I quit, I think they got the machine going. I know they will have to do ballscrew pitch comps still.
