    So replace with a primary lithium battery and a blocking diode (or MOSFET) and sit back for several years of botherless operation...

    That's been my approach, though usually I just remove the trickle charge resistor.

    I was faced with this same choice recently; replace the old NiCd with new NiCd, replace them with NiMH, replace them with Lithium rechargeable?

    What I decided was to get the parts to make 3 x AA external battery packs with nice long leads and DuPont connectors. I've never had a problem with even 4 x AA packs, so, plug them in, change the batteries when they need it and have a lifetime of trouble free use.

    If they ever leak, they leak off-board, but, I've never had that problem.

    Use primary lithium batteries, not rechargeable ones. You'll get at least 7 years out of them and they won't leak. See my and glitch's post above.

    At the time that NiCd rechargeable cells were being used, lithium primary batteries were fairly expensive. With today's batteries, the NiMH battery really won't last much longer than a lithium coin cell.

    Too late now, I've already got the stuff to make up 50 3 x AA packs.....
