Keeppower 18500 1500mAh (Black) 2014



Official specifications:

• Typical Capacity: 1500mAh
• Normal Voltage: 3.7V
• Quality Lithium Ion rechargeable cell ICR18500 made in China
• In Built Safety Circuitry
• Maximum capacity and reliability
• High Discharge Rate (Max 2C)
• Protection Circuit (Against overcharge, over discharge, over current and short-circuit.)
• 4.2 volts max voltage and 3.6-3.7 volts nominal voltage
• Over 300 charge-discharge cycles

Keeppower sells two version of 18500, this one is the cheaper version from DLG. The other version uses a Sanyo cell.











The battery does very fine up to 3A load, that is 2C and matches the rated 2C maximum discharge. Drawing much more than 3A does not really work.















Conclusion

The performance looks average for 18500 batteries, but they are not designed for high current.
I will call the cells acceptable.
