How to charge an internal battery in a killed Wallaby?

[Sallala]

I have got a GSM-ROM killed wallaby. It's battery used little time.

I use another Wallaby it works fine. I like to keep the killed one's battery in good condition, because if the working one's battery go wrong (about half or one year) I like to change it.

As I know, if a Li-ion Polimer accumlator is deep discharged it go wrong. So I must to charge it sometimes. But as I see, the killed Wallaby does not charge its battery. The led is red, not orange, and if I unplug the charger the pad switch off immediatly.

I have got only a sync cable, dont have docker. Can I charge the battery, when I connect the three connectors to the working Wallaby's three connector on the units back side?

Hmm maybe I can change the bateries sometimes beetwen the working and tha not working device, but in this case, I need to disassemble the units, and it will hardreset the unit.
I is not a good solution.

Can you check this thread may be the answer is there, but you will have to diss-assemble your ppc, don't have to put it back until you start repairing it.
