NiMH Charging problem

I bought a 2500 mAh JR NiMH battery pack two seasons ago and it has charged flawlessly many times (say 10) on my Super Nova 250S charger. I last cycled it about 3 months ago.

I went to charge it recently and I could only get about 250mA into it before the charger said it was full. I discharged and got 250mA out. Re-charged and got only 74mA in, etc., etc., with discharge/charge values between 75mA and 250mA. I did the discharge/charge at 1.0A but also tried it at 0.2A with no improvement.

To check if the charger was acting up I charged up a 2000mAh NiCD pack and it worked just fine.

I took the battery pack to A & J today and Arden was able to get 1900mA into her using a Triton.

Any idea what the problem could be? My Super Nova was used when I bought it. Could it be dying? I was thinking that I should try to cycle it again on my Super Nova now that I know the Triton had no issues.

Comments? Thanks,

CFB
