Is this battery any good?

[Urs Baertschiger]

If it is a NiMh then replace it. If it is a NiCd then cycle it at least 5 
times and check the capacity you get out of it every time you discharge it. 
If capacity isn't increasing and eventually gets back to at least 1700mAh 
then replace it too. Best is to charge it during cycling at 1/10C for about 
16 hours.
Once you get back to 1700mAh I'd do another check. I'd leave it fully 
charged for approx. 2 weeks and check the capacity again. If capacity is 
below 1600mAh the pack is on its way south.
My 2 cents of experience.
