Hi,

My ageing smoke alarm needs a new 8.4v 30mAh NiCd Cell (about the size
of an AAA battery) with flat top. I'm not really clued up on
electronics. I assume the 30mAh is the charge hold value and it doesn't
matter if I get a cell with a higher value?

Anyway, any idea where I can get a replacement, have looked in Maplins
but to no avail.

Thanks

David
