Characteristics of Samsung INR18650 32E
1. Standard Charge
This “Standard Charge” means charging the cell with charge current of 960mA and constant voltage 4.2V at 25°C, 0.02C cutoff.
2. Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 640mA with 2.50V cut-off at 25°C within 1 hour after the Standard charge.
Standard Discharge Capacity ≥ 3,100mAh
3. Rated Discharge Capacity
The rated discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 3,200mA with 2.50V cut-off at 25°C within 1 hour after the Standard charge.
Rated Discharge Capacity ≥ 3,007mAh (97% of 3,100mAh)
4. Initial Internal Impedance
Initial internal impedance measured at AC 1kHz after Standard charge. Initial internal impedance ≤ 35mΩ
5. Temperature Dependence of Discharge Capacity
Discharge capacity comparison at each temperature, measured with discharge constant current 3,200mA and 2.50V cut-off with follow temperature after the Standard charging at 25°C.

WARNING:
The user must have an appropriate understanding of lithium-ion batteries before purchase. Use caution when working with and using lithium-ion batteries as they are very sensitive to charging characteristics and may explode, burn, or cause a fire if misused or mishandled. Always charge in or on a fireproof surface. Never leave batteries charging unattended. Buyer is responsible for any damage or injury caused by misuse or mishandling of lithium-ion batteries and chargers. No express or implied guarantee of compatibility with any device can be made. Charge only with a smart charger designed for this specific type of lithium-ion battery. Do not mix and match old and new, used and unused batteries.
