Sanyo GA cells temperature rise during charging

[Overclocker]

even when charged at just 1.0A per cell they seem to get noticeably "warmer" than my other cells e.g. Samsung 26F

by warmer i mean about ~5 degrees C over ambient

my samsungs get only about ~1 degree over ambient, at the same 1.0A charging current

anyone noticed this too?

What voltage are you charging to, and what is your final charge current cut off ?
I charge GAs at 2.5 amp , to 4.15 v, with no noticable temp rise.

i observe a temp rise at any voltage. but i usually charge to 4.10v

here's the pack

No good reason for them to be getting warmer than 26F's. You sure about that?

GA's have about half the resistance of 26F's, and are rated at half the current output.

You sure the heat isn't caused by something else?

At 1A they shouldn't even be breaking a sweat. Maybe 1-2C over ambient temperature.
