Hi,
Okay, now I'm confused and this is why I asked here seeking informed opinion. I did some searching before asking this question and there seems to be a lot of contradictory advice out there about suitable replacements for ni-cads.
The big problem for me is battery leakage, so from that standpoint NiMH is not a good option as it seems they can leak just as badly. The consensus seems to be that Lithium batteries are the least likely to leak, though they can in very rare and extreme conditions.
Lets be clear that I am talking about using a non-rechargeable and fairly high capacity Lithium battery (AA size probably) and removing or blocking the existing charging current in the way described by Jesper. It works for him and I think it will be a good solution for me too. Also I have seen people using Lithium CR2032 button cells to provide memory back-up in TR-606's and TB-303's so it does seem to be a workable solution.
Cheers, vout
