Those Sanyo's have a reputation around here for getting hot while charging (search the forum for "Sanyo heaters". If you feel them you will find they are very hot, so most of the power is being burned off as heat, resulting in abnormally high mAh readings and extended charging times while it tries to get the cell up to 4.2V

Shall I avoid them then ? how can I know the real capacity then ?
Korishan said:+1 with Seans comment about "discharge test". When charge testing, the charger has no way of knowing what is being converted to heat, unless you get a really expensive piece of equipment.
The discharge test is the one that will give you real world capacity values, or at least pretty close.
As far as heating is concerned, there are many threads on here about "Sanyo Heaters". There's basically two groups of people on the subject. One group says toss them without a second glance, the other group says to cycle them a few times and if the heat produced goes down (usually rather quickly each time) and the capacity comes up, then they are fine. Each person needs to address what they feel safe with and make an educated decision.
