Hi all,

I have a Kuhnke 680 PLC that has an onboard battery that is totally dead, so loses all settings when it is shutdown.

The batteries have no markings, there are three in series soldered to the board.

Does anyone know if these are rechargable or non-rechargable type in these types of PLC's?

I have been told they are 3.6V (ie 1.2V per cell, which makes sense)

Thanks,
Rod
