MacAllister batteries

[Simpo Two]

I have a perfectly good MacAllister cordless circular saw. The only snag is that it has Ni-Cad batteries which now being 17 years old are useless.

Is it possible to buy a Li-ion replacement? I fear not, in which case the whole thing will have to go to landfill, but thought I'd ask just in case.

One option is to replace the batteries:

The other option is to try & find an adapter.

I can find them for DeWalt & Makita, maybe there’s some cross compatibility?

Thanks for the ideas, though both ideas seem high risk.

The cordless saw is useful sometimes because it has a very clean cut - I think because the blade is thin and designed for low friction - whilst a normal corded saw is a bit rough.

When it was new I needed to cut a gentle curve into a 40mm wood worktop; I applied some side pressure and to my surprise not only did the saw manage the curve, but it was such a clean cut it didn't need planing or sanding! Are all cordless saws like that or was I just lucky?

Most circular saws are rough because they tend to come with ridiculously over specced discs.

Make sure you note the rpm & the disc spec of your current one when looking for a replacement.

I suppose I could look for the same spec disk that the cordless one has and put it in the corded one, allowing for the centre hole size. Never thought of that!
