Safety instructions: Li-ion batteries should only be operated with a so-called protection electronics. Please note that lithium cells may only be used by authorized personnel. 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 specifications for Trustfire 26650 5000 mAh 3.6 V - 3.7 V protected Li-ion battery.

Notes: Charging lithium-ion batteries (Li-ion) requires a special charger that charges the batteries according to a specific charging method (CCCV = constant current, constant voltage). The batteries must not be charged beyond 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 approximately 4.1 volts, as this significantly increases their lifespan and number of charge cycles. Only lithium-ion chargers should be used for charging. However, cheap chargers sometimes have the disadvantage of not shutting off safely after the charging process is complete.
