The version that pdlouche linked to ticked all the boxes as far as spec is concerned and for £40 more than the normal 'not for lithium' type that makes sense to me. I'll contact them and see what kind of assurances they are prepared to offer.
The alternative is trying to find out voltage range and ripple on the standard types to see how different they are.
Could try out the old mechanical version that's been in a box for ten years!
