My brother in law has just given me a Fein multimaster 500 ampshare bare unit he got it as a freebee (lucky him lucky me I think) just had a quick look at batteries and chargers and it seems to me Fein batteries and chargers seem a lot more expensive than Bosch ones and I know the Bosch green stuff is not compatible but the "Professional " range is .

There is some batteries labelled ampshare but from what I can take from the little info I have read any Bosch battery from the professional range 18v should be cross compatible, anybody share anymore light on the subject please.

Thanks.

Took the plunge and bought a Bosch battery and Bosch charger from the "professional " range and it fits and works great.

I saved £25 on the battery £5 on the charger.

Every little helps.
