Cell Database Submissions and Updates
Unknown 18650 cell from a laptop. Sleeve was not shrink wrapped and would roll right off if pushed. No markings on the sleeve.

Cell was marked:

Came from an HP f2024a battery. Sanyo part number SI-CPL11U. Did Sanyo made the cells?

Marked capacity is 1800 mAh. Tested capacity was <100 mAh and most of them where open circuit :-(

Cells tested: 4087
Average capacity: 2082 mAh
Left to process: 165 kg

2200mah 3.6v cell

datasheet: IMR18650E22 datasheet

I think I've got something new here for the database.  Spotted these in the recycling bin at work and thought I would test them out.  One needed a trickle charge but the tested out at 2555, 2679, and 2712

Specs are available on the website:

Model: IMR18650

Rated capacity: 3000mAh
Nominal Voltage: 3.7V
Voltage cut-off: 2.5V
Max Charging Current: 4A
Standard Charge: 2A
Discharging Current: 20A
Plus Discharging Current (their words not mine): 35A
Charging Temperature Range: 0 - 45C
Discharging Temperature Range: -20 – 75C
