Which batteries for 41CV?

[HP67]

Thanks guys, apparently the LR1 is an alkaline rather than rechargeable. I have a 12 pack of Duracell E90s coming which ought to be good to start with.

I am in Europe but I think we have digikey or mouser local sites. The only problem is they usually have a minimum purchase of 50 Euros. I've been meaning to get some other goodies, so...!

Horrible about destroying calculators with the wrong batteries.. I will certainly read the fine print before I put anything in the battery holder.

I didn't find a dedicated charger after all but I'll keep an eye open for sources of rechargeables and chargers. I guess it wouldn't be too difficult to put together a charger for cheap using a 4xAA battery holder with long springs or shims of some kind.

Thank you!
