HP Portable Plus battery / battery cover

[Martin Hepperle]

Diedier,

in Europe you can find the individual cells under the brand name Hawker-Cyclon.
You will need three of the 2V / 2500 mAh cells and some (simple) soldering skills plus some large diameter shrink wrap tube (also available from some shops.

I Germany I find such cells e.g. at
http://www.akkushop.de/
(battery==akku in German) while I bought some cells via Amazon from another company.
Cost per cell should be about 10 EUROs or less
(Hawker Cyclon Cyclon 2.5-2, 0810-0004 Akku Blei 2Volt 2500mAh)

There is nothing special to make these batteries. I reccommend to add a fuse of about 2A to the battery pack to avoid blowing the fuse on the mainboard, just in case.
Another desirable improvement would be to add a connector to the cables and not to connect the battery directly to the mainboard vial cables and "eyelets".

For the battery door I have no idea except making a replacement using a 3D printer.
I have added some thin foam tape to the battery pack and it would also stay in place without a cover.
