Sanyo

NCR18650-GA

The Sanyo GA is a pop­u­lar cell with a high ener­gy den­si­ty.

Capac­i­ty
[def­i­n­i­tion]
All quan­ti­ties are mea­sured in the bat­tery lab­o­ra­to­ry of Bate­mo GmbH. The capac­i­ty is mea­sured by dis­charg­ing the cell at an ambi­ent tem­per­a­ture of 25°C from 100% with a con­stant cur­rent of 1.75A (0.5C) until reach­ing a volt­age of 2.5V. The ther­mal bound­ary con­di­tion is free con­vec­tion.
nom­i­nal 3.50 Ah
coulom­bic 3.20 Ah
ener­getic 11.5 Wh
Ener­gy Den­si­ty
[def­i­n­i­tion]

The ther­mal bound­ary con­di­tion is free con­vec­tion.
gravi­met­ric 244 Wh/kg
vol­u­met­ric 693 Wh/l
Pow­er Den­si­ty
[def­i­n­i­tion]
All quan­ti­ties are mea­sured in the Bate­mo bat­tery lab­o­ra­to­ry. The cell pow­er is defined to be the pow­er the cell can deliv­er for 5 min­utes. There­fore the cell is dis­charged from 100% SOC at an ambi­ent tem­per­a­ture of 25°C with a con­stant cur­rent until either the volt­age of 2.5V or the sur­face tem­per­a­ture of 60°C is reached after 5 min­utes. The ther­mal bound­ary con­di­tion is free con­vec­tion. This oper­a­tion of the cell might be out­side the spec­i­fi­ca­tion of the cell man­u­fac­tur­er.
gravi­met­ric 943 W/kg
vol­u­met­ric 2.67 kW/l

Sam­sung

INR21700-40T

The Sam­sung 40T is designed for high pow­er appli­ca­tions such as elec­tri­cal screw­drivers, ham­mer drills, chain­saws and leaf blow­ers.

Capac­i­ty
[def­i­n­i­tion]
All quan­ti­ties are mea­sured in the bat­tery lab­o­ra­to­ry of Bate­mo GmbH. The capac­i­ty is mea­sured by dis­charg­ing the cell at an ambi­ent tem­per­a­ture of 25°C from 100% with a con­stant cur­rent of 2.00A (0.5C) until reach­ing the low­er volt­age lim­it of 2.5V. The ther­mal bound­ary con­di­tion is free con­vec­tion.
