Just for clarity sake:
FROM BATTERY TESTER the “Mooch”:
“The datasheet for this cell lists a 35A “maximum discharging current” rating but notes that “cycle life is reduced at high rates”. This means Molicel says you can use the cell at up to 35A but the cell will age faster.
The only maximum temperature limit I can find in the datasheet is 60°C so never allow the cell to get hotter than this. Cells start aging a lot faster when run at temperatures that high, above around 45°C, so it’s best to stay below 45°C whenever possible.
Be aware that going over 60°C is very easy in a battery pack where each cell can heat up the ones around it and the pack is covered by insulating materials that slow down cooling.
This 35A rating not a true continuous current rating you can use to compare against other cells. The P28A will get almost hot enough to boil water if run continuously at 35A down to its 2.5V cutoff. In my opinion Molicel rated this cell for its intended use in power tools and other applications where the cells are used only for short periods of time at high current levels.
So while you can run this cell for short periods at 35A I recommend staying at 25A or lower to help improve performance (reduce voltage sag), extend cell life, and reduce the risk of going over the 60°C limit.”

These tests below only note my personal ESTIMATED ratings for the batteries I tested at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, or Sanyo can change at any time! This is one of the...
