my battery ended up only holding 20mins power(and getting HOT! when charged).
yours (@tramp) seems to have gotten worse than that.
1- try to get hold of replacement battery,
2- risk-it and modify the battery yourself(
*DANGERS AND WARNINGS
notes before modding/repairing:
1- Lithium-Ion draws more current when charging than Lithium-Polymer,
however the archos 04 can handle upto 18Ah Li-Ion batteries(tested so far).
2- *The battery is a B!#ch to dis-assemble and you don't want to pierce that battery(AT ALL
3- The Archos 04 charges individual cells of my 9Ah Toshiba battery pack quicker than the laptop itself.
4- Have equiptment at ready; solderind iron; multimeter; desoldering kit(of any favourble sort).
5- *Always note the polarity.
1- Remove pack from device,
2- Dis-assemble pack,
3- Note polarity on pack and jot a note/diagram/etc to aid in replacement,
4- Carefuly cut the tabs on battery away from controller (don't short whilst cutting),
5- Check nothing appears burnt on the controller,
6- Desolder the remaining tabs away from controller(avoid over-heating board),
7- Get and tin some coloured wire (preferably red/black for consistency),
8- Solder the wires to the controller in a way so the colours makes sense with polarity
(ie red to + and black to -),
9- Depends on what lithium battery you are using, connect the wires to their respective polarity
on the tabs of the lithium battery according to the manual or determined by a multimeter,
10- Re-assemble battery pack into/onto the archos 04 and use as new.
any feedback is appreciated.
