Red, thanks for the assurance ! Just out of interest, is there any reliability test for batteries done at Sanyo to assess the separators ? What kind of current or temperatures can the separators withstand before they are "punched through" ?
The separators act to contain the electrolyte and provide ion transfer, it is not effected by the actual current drawn from the cell other than by any heat generated. The failure mode attributable to high currents is more likely to be burn off of the internal cell roll to positive button. The separator deterioration is an oxidation issue which is a rather slow process which is accelerated by extended exposure to high temperatures.
