Default RE: Batteries running-in and swollen batteries

Hi,
For the last 3 or so years most brands are giving more cycles.
As a result we are generally happy with them ,if for no other reason than they were better than the previous lot.
One thing that I have noticed (I don't get through that many packs anyway) is that it is just one or two cells that let a pack down.
I would say that this is the case in 75% of cases - small sample though.
Anyway,picking up on Brenner's point, new packs are generally better than their predecessors and as a result it is easy to conclude that they are doing well regardless of treatment.
So it is difficult to know what is best. Would the pack with 200 cycles have done 250 ??
There is no doubt that over-discharge by rate (difficult for us) or by volume is the big no-no.
