Savings and Sustainability: Being fully reusable and able to withstand hundreds of charge cycles, it reduces environmental impact and recurring costs compared to disposable batteries.
Versatile Compatibility: Fits perfectly with a wide range of portable applications, such as professional LED flashlights, photographic equipment, security systems, and electronic toys.

Safety and Care:

CRITICAL SAFETY NOTICE (Lithium Batteries): Lithium-ion cells store a massive amount of energy. NUNCA store or carry loose batteries in bags, pockets or backpacks in contact with coins, keys or metal objects. This friction closes the electrical circuit of the poles, causing mechanical short circuits with a severe risk of fire or explosion. Always store them in appropriate protective cases or covers and insulators.
Regular Visual Assessment: Visually inspect the cell before each operating cycle. If you detect dents on the housing or if the protective wrap is slightly worn or torn, suspend use immediately. Find replacement wraps and protective covers in our store.
Paired Cells (Matching): In equipment operating with two or more batteries simultaneously, always use identical cells (same brand, model, nominal capacity and chemical wear level).
Circuit Limits: Honor your device’s factory specifications and never push the circuit beyond the continuous discharge limit of 20A for this battery.
Safe Charging: Charge on a dry, non-flammable surface and keep the process under supervision. We strongly recommend using a proper external battery charger to preserve the cell’s lifespan.
Responsible Disposal: Never dispose of spent lithium batteries in regular household waste. When they reach the end of their life cycle, deposit them at an electronics waste or battery recycling point for ecological recycling.

Usage Instructions:

Initial Stabilization Charge: Before first practical use, perform a 100% recharge on a smart external charger to calibrate the chemical properties of the cell.
Polarity Alignment: Make sure to insert the battery respecting the correct orientation of the positive and negative terminals (+ and -) marked on your device.
Active Charge Management: Place the cell on charge as soon as you notice a visible drop in performance or when the indicator shows 20-30%. Avoid full discharge to protect the internal chemistry and extend its lifespan.
Long-Term Storage: If you decide to store the batteries unused for several weeks, keep them at about 50% charge in a cool, dry place, fully protected from heat sources or sunlight.
Contact Maintenance: Periodically clean the cell’s flat terminals to remove dust or residues, ensuring optimal electrical conductivity.

Usage Tips:

When traveling or on the move, always remove the cells from the inside of your electronic devices and transport them separately in a suitable carrying case to cushion impacts.
In case of any suspicious operating behavior — such as excessive heating beyond normal, odors or physical deformations — stop the circuit immediately and contact us.
