Test results (discharge curve) comparison test detailed test results Lygte-Info. Safety notes: Lithium cells should only be operated with protection electronics! Please note that lithium cells may only be used by authorized professionals. Improper handling or short circuits can lead to fire or explosion. Additional features: Lithium-ion batteries are thermally stable and do not suffer from memory effect. They operate on the basis of lithium and are characterized by a high energy density. Technical data for "Keeppower IMR18650 - 2900mAh, 3.7V Li-Ion Battery 10A (Flat Top)": Normal charging current 1375mA/3h, operating temperature charging 0 °C - 45 °C, operating temperature discharging -20 °C - 60 °C. Notes: Charging lithium-ion batteries requires a special charger that charges the batteries using a specific charging method (CCCV = constant current, constant voltage). The batteries must not be charged above a voltage of 4.2 volts, as this poses a risk of fire and explosion. It is advantageous to charge the batteries only up to about 4.1 volts, as this significantly increases their lifespan or number of charge cycles (potentially doubling it). Only lithium-ion chargers should be used for charging. However, cheap chargers sometimes have the disadvantage of not safely shutting off after the charging process is complete, but continue to charge the batteries with a small current.
