Safety and Care:

  • CRITICAL SAFETY NOTICE (Lithium Batteries): Lithium-ion cells contain massive amounts of energy. NUNCA Transport or store loose batteries in pockets, backpacks, or wallets together with coins, keys, or other metal objects. Direct contact with terminals causes an immediate short circuit with a serious risk of fire or explosion. Always use suitable protective cases or protective covers to insulate the terminals during transport.
  • Visual Inspection: Before each use, check the battery integrity. If you find dents in the structure or the insulating wrap is torn, stop using the cell immediately. Find wraps and replacement accessories in our shop.
  • Cell Pairing: If your device uses more than one battery at the same time, ensure that all are exactly the same (same brand, model, capacity and cycle history).
  • Operational Limits: Do not exceed the discharge rate of 40A and strictly follow the specifications of your device's manufacturer.
  • Safe Recharging: Use a proper battery charger and external. Avoid unsupervised charging and only use dry, non-flammable surfaces.
  • Conscious Disposal: Spent lithium batteries are not ordinary trash. Recycle them at an electronics waste recycling point or an authorized collection point.

Usage Instructions:

  • Calibration Charge: Before first use, perform a full charge cycle on an intelligent external charger to prepare the battery's internal chemistry.
  • Correct Polarity: Always check the alignment of the poles (+ and -) when inserting the battery into the device.
  • Prevention of Deep Discharges: Recharge the battery before it reaches 20-30% charge. Avoiding a full discharge preserves the cell chemistry and extends its life.
  • Long-Term Storage: Store the cells with about 50% charge in a cool, dry place away from direct sunlight.
  • Maintenance: Keep the battery contacts clean to ensure efficient electrical conductivity.

Usage Tips:

  • When traveling, remove the batteries from the devices and store them in a proper carrying case to prevent damage from impacts.
  • Any sign of unusual overheating, leaks, or physical deformation should lead to immediate suspension of use and contact with our support.
