and apologies again! (it's late here ^_^ ) - just saw your other message - yes it's whatever the current version of the Z3A65 is. i was able to find a replacement here in the us, but as i said that was some years back. maybe Dieter knows where to find some?

    that's not it. i am sorry i can't remember or find the exact part number, but it's shorter, with a 3-pin mount. go ahead and open up your Regelwerk and take a look, there should be a part number on the battery you can match. wish i could be more help!  :-)
