  • Ahlborn Archive battery replacement

    I'm hoping someone can help me. I have 2 Ahlborn Archive modules, plus one at my former church. One of the units needs to have its battery replaced and I'm guessing the other two would be about due, too.

    I've done this maintenance in the past, but I can't remember if I changed the battery with the unit powered on.... so I don't lose voicing or presets. Can someone provide some advice as to whether or not this is a good idea.

    thanks for your advice!

    Hi,

    The batteries in the Ahlborn Archive modules, and Ahlborn-Galanti organs, should be replaced at least every 6 to 8 years. If you let them go for more than 10 years, there is a good chance that they will begin to leak battery acid, and potentially do harm to connectors or circuits.

    As for changing the battery pak, the unit must be turned off. These are solder in type. You need to do rather extensive dis-assembly to take the battery out and put the new one in. If you want to make things easier in the future, solder in some extension wires, and then wire it to a cordless phone battery pak. Put some velcro on the battery pak and somewhere convenient in the unit, so the battery does not bounce around when moved.

    You will lose settings when changing the battery. Best to write down the settings before getting started. I avoid this in the organs, by temporarily putting a battery pak in parallel to keep voltage on the RAM while doing the replacement procedure.

    The battery pak I use is a NiMH (instead of the original Ni-Cad), pak which I source from Battery Bob in the US - part # - COMP-16-3NMH

    I hope this is useful to you.

    If it is less than useful, just hit the delete button.

      Thanks for the advice. I was thinking about putting a battery in parallel as I don't want to revoice everything! I think you may be able to dump the settings to a sequencer, but I've not gotten that to work in the past. I think it may have been the sequencer, however.

        Well I'm happy to know that. Thanks Arie. I've had 2 for 10 years and didn't know they had batteries in them. I'll order your part number. Hopefully I can do the job myself.
