I was going to say use NiMh it won't matter. But someone said they're no better or worse. If you are looking at it from an environmental viewpoint, NiMh are less polluting than NiCd.

Someone else said NiMh don't like overcharging, I was under the impression NiMh could be charged at any time irrespective of their charge status, whereas NiCd should only be charged when empty. And NiMh could be charged for as long as you like. whilst NiCd don't like overcharging. I await confirmation from a higher source.

Can I also hijack this thread, now that it has been answered, and say that Braun used to sell just the foils as replacements, now you have to buy the foil and top plastic curvy thing (connected) along with a new cutting blade, costing about 13 - 16 pounds (which happens to be 1/3rd the price of the new machine!) My shaver is stuck in a draw after the foil lasted 3 - 4 weeks, no way am I going to pay all that money when all I need is a pack of 5 foils like we used to be able to buy!

Has anyone else noticed this and/or know how to obtain just the foils?

Thanks
