HELP Ipaq Wireless Pack Battery Critically Low

[Wrathyimp]

Hi,

I gave my ipaq 3970 with gsm/gprs WP to a friend, but he didnt charge it for a month, then he returned it back to me. Now i have kept it on charging for more than a day, and it Wireles Pack (WP) is till warning of battery critically low.
Extended Battery Fault:
Your Extended Battery has become critically low.
The expansion pack will be powered off. To continue using this expansion pack, you will need to charge it.

I want to know how can i fix this problem. Or my battery is dried out or dead. is there any ways i can fix it.

Thank You.

It sounds very much like the battery's dead - it's usually not a good idea to have the battery run down too far. *sigh* That's what friends are for, right?

Is there a way that i can check its really dead, just to make sure.

I have heard that there is a way we can flash the battery, and then re-use it again.
