guver, Here's my results (if I can tabulate the data intelligently)

Charge (mAH) Discharge (mAH)
484 561
642 742
731 855
821 813
898 876
904

So, except for the 855 number it seems to make sense. Increasing capacity with exercise. Also, I've read that the actual numbers will vary depending on charge and discharge current.

The battery pack came from NitroPlanes as part of the RTF Catalina. Not likely I could get a replacement. But doesn't the temperature rise depend on the charger characteristics. I read that if I overcharge, the excess energy is given off as heat. So if my charger is overcharging to some small degree (delta peak sensitivity) I could expect the pack to warm up. It did so towards the end of each charge cycle.

What do you think?
