Safety and Care:

CRITICAL SAFETY WARNING (Lithium Batteries): Industrial lithium cells store a massive amount of energy. NUNCA Do not transport or store loose batteries in suitcases, backpacks, or pockets with keys, coins, or any metal objects. Direct contact closes the electrical circuit, causing immediate short circuits with a high risk of explosion or fire. Always use suitable protective cases or covers and insulating materials.
Inspect Before Use: Visually inspect the cell regularly. If you notice structural deformation, dents, or tears in the outer insulating plastic film (wrap), stop using it immediately. Find replacement wraps and accessories directly on our website.
Manage as a Set: In devices that require more than one battery, always use strictly identical cells (“married” cells) in terms of brand, model, capacity, and life cycles.
Technical Limits: Operate your equipment within the recommended limits and never exceed the continuous discharge limits of 20A (60W) or the pulse discharge limits of 45A (100W).
Safe Charging: Charge batteries on non-flammable surfaces and under supervision. We strongly recommend using a suitable battery charger and external to preserve the cell's chemical health (maximum charging limit: 4A).
Eco-Friendly Disposal: At the end of its service life, never dispose of the battery in household waste. Take it to a battery recycling bin or an authorized electronic waste collection point for recycling.

Instructions for Use:

Initial Calibration: Before the first cycle of practical use, fully charge the battery in a dedicated external charger to optimize its service life.
Observe Polarity: When inserting the cell into the electronic device's compartment, carefully check that the positive and negative poles (+ and -) are correctly oriented.
Preventing Deep Discharges: Start charging the battery as soon as you notice a substantial drop in performance or when the level indicates around 20-30%, extending the durability of its internal chemistry.
Safe Storage: If you do not plan to use the batteries for a long period, store them at around half charge in a dry, cool place, completely isolated from direct heat sources.
Contact Maintenance: Clean the battery's flat terminals and the device's contact pins regularly to prevent electrical faults or loss of conductivity.

Usage Tips:

When commuting or traveling, always remove the cells from inside the devices and transport them safely and individually in a suitable carrying case to protect them from impacts.
If you detect any signs of operational abnormality (such as sudden extreme heating, strange odors, or liquid leaks), stop using the battery immediately and contact our technical support team.
