The battery should be partially charged for long-term storage – 50 to 80 %.
The battery should be charged at an ambient temperature of 0 °C…+35 °C (+32 °F…+95° F). Otherwise, lifespan of the battery will decrease significantly.
When using the battery at sub-zero temperatures, the battery capacity decreases, this is normal and not a defect.
Do not use the battery at temperatures outside the range of -25 °С...+50 °С (-13 °F…+122 °F) – this may reduce battery’s life.
The battery has a short-circuit protection. However, any situation that may cause short-circuiting should be avoided.
