Description

Used Sony US18650VTC5 battery cells, processed, tested, and approved for further use.

Two variants (grades) are available:

  • G1 (Grade 1)
    - SOH (State Of Health) is in the range 95-100% | avg.: 96.58% (new cell = 100%)
    - iR (internal Resistance) is in the range 29-41mΩ | avg.: 36.20mΩ (new cell = 30.0mΩ)
  • G2 (Grade 2)
    - SOH is in the range 91-98% | avg.: 94.82%
    - iR is in the range 33-57mΩ | avg.: 44.15mΩ

The reason G2 overlaps with G1 is due to the fact that the cells might have a good SOH (e.g. 97%) but worse iR (e.g. 35mΩ) and vice versa. Therefore a separate grade for lower price.

  • Tested for self-discharge
  • Capacity tested at 1C current (2.6A)
  • DC internal resistance measured according IEC 61960-3:2017, paragraph 7.7.3 (Note that DC IR is very different from the more commonly used AC IR)
  • All measurements were carried out using calibrated custom-designed equipment
  • About 99% of cells are fitted with new shrink wrap and insulator (Note: new wrap has no markings on it)
  • Residuals from spotwelds were carefully removed leaving a smooth surface for spot-welding (see gallery)
  • We provide a spreadsheet with parameters of each cell in your order. The parameters include cell ID, capacity [mAh], energy [Wh], DC iR [mΩ]
  • All cells are shipped at 3.5V (+-0.03V)

Specifications of a new cell:

  • Nominal capacity: 2600 mAh
  • Nominal voltage: 3.6 V
  • Discharge end voltage: 2.5 V
  • Charging voltage: 4.20 +/- 0.05 V
  • Max. continuous discharge current: 20A
  • Standard charging current: 2.5 A
  • Length: 65.30 mm
  • Diameter: 18.3 mm
  • Weight: 44.6 g
