Hi Nick! I have done such an upgrade of an old lib 110 battery pack. Unfortunately I can't remember the exact type number for the Panasonic cells I used, but they should have a slightly higher capacity than the original! See my post from May, 10th 2005, which I repeat here: Although it was a success and I have a working battery now, I wouldn't repeat it! According to my experiences it is impossible to open a battery pack without visible scratches or cracks. I also tried to take 2 dead packs, where I cutted off upper part on one and the lower part on the other - to work out the other half unbroken. This gave better results, but is also not perfect. The packs are designed and glued in a way that it makes impossible to separate the two halves without signes! The other thing are the welded contacts. Without a special welding equipement (which I do not have) the only way is to solder the contacts with wires. I tried to use thin (but not too thin!) wires, I grinded it flat, but the batterys need still 1 mm more space inside - and this space is not available. I tried to grind away some plastic, but there is not much.... So on the left and right side the renewed pack is still a litle bit bulgy. And the new pack seem to have less capacity as a hi-capacity pack in good condition. Also the rebuilt pack looses charging faster than the original if it is unused for a while! So my conclusion is: not recommendable. :-((( regards Gerhard _________________________________________ Gerhard Kapusta Fax&Voicebox: +4989-1488201115
