Capac­i­ty
[def­i­n­i­tion]
The nom­i­nal capac­i­ty orig­i­nates from the man­u­fac­tur­er’s data sheet, if avail­able. When the data sheet is unavail­able, the nom­i­nal capac­i­ty is esti­mat­ed. Bate­mo mea­sured the C/10 capac­i­ty by dis­charg­ing the cell at an ambi­ent tem­per­a­ture of 25°C from 100% with a con­stant cur­rent of 6.50A (0.1C) until reach­ing the volt­age of 2.5V. The ther­mal bound­ary con­di­tion is free convection.

Cur­rent
[def­i­n­i­tion]
All quan­ti­ties are mea­sure­ment results of the Bate­mo bat­tery lab­o­ra­to­ry. The con­tin­u­ous cur­rent is the high­est cur­rent that com­plete­ly dis­charges the cell with­out over-heat­ing it. There­for, the cell is dis­charged from 100% state of charge at an ambi­ent tem­per­a­ture of 25°C with a con­stant cur­rent until reach­ing a resid­ual state of charge of 10% and either the volt­age of 2.5V or 90% of the max­i­mum sur­face tem­per­a­ture of 54°C. The peak cur­rent is the cur­rent the cell can deliv­er for 5 min­utes. Con­se­quent­ly, the cell is dis­charged from 100% SOC at an ambi­ent tem­per­a­ture of 25°C with a con­stant cur­rent until reach­ing either the volt­age of 2.5V or the sur­face tem­per­a­ture of 60°C after 5 min­utes. The ther­mal bound­ary con­di­tion is free con­vec­tion. These oper­a­tional con­di­tions might be out­side the spec­i­fi­ca­tion of the cell manufacturer.
