Well, maybe i should change thechnology for the available, then... But theese in farnell are too tiny, 65mAh. (and multiple =3D too expensive) Farnell recommends 0,2mA charge -that will take too long.=20 I=B4ll look other places for Lithium-Manganese. BTW, whatever happened to rechargeable Lithium Vanadium? I remember designign a product with them. This is not one-off, it is for small production 100/yr+ hopefully. /Morgan -- http://www.piclist.com#nomail Going offline?
