Re: Varta 2/V60 Ni/Cd cell? equivalent?

I'm looking for a battery to replace the one in my Landis& Gyr C/H

Number of cells? Actually, if there is physical room, probably the easiest way is to buy several AAA NiCd cells, a battery holder, snip off the old leads high on the battery, and solder on the battery holder.

Assuming they're NiCads, anything nearly the right size will work ok - assuming the correct voltage (number of cells). I'd also guess that using NIMh in this application as a direct replacement will also be fine, given that NiCads are getting harder to find.

[Dave Plowman (News)]

I'd agree. But nevertheless they're being sold for this express purpose. And as the OP has found, most have discontinued NiCads of this type.

Whoops. Just two, so a bit under 3v nominal, and the unit puts about 3.5 v across them.

The package of 2 batteries is about a 16mm dia by 12 mm high cylinder, my problem is that I haven't come up with anything rechargeable around that size.

I could bodge some sort of battery box, but it would be nicer to fit them in the casing.

have results. I'd check CPC first.

Thanks Ian, I had tried them, (or someone would have slapped my wrist)

But my post below should add one to your list
