### Toshiba Impulse 2400 mAh Accelerated Cycle Testing

I've included the results (in green) for a similar Eneloop XX cell on the above chart.

A few interesting points to be noted from these results:

A few interesting points to be noted from these results:

- Despite being rated for a lower capacity (2400 mAh Vs 2500 mAh for the Eneloop XX) the Toshiba Impulse had higher capacities at low discharge rates. I think that it would be reasonable to actually swap the ratings!
- The Toshiba cells lasted for less cycles, but considering the cell to cell variability and the fact that the Eneloop was tested at a different time, the differences may not be as significant as this chart suggests (although it could be even greater)
- At high discharge rates, the total capacity was similar for all 3 cells for the first 80 or so cycles.
