180-Day Warranty & Customer Support

Every cell batch supplied by DXF POWER is covered by a 180-day manufacturer warranty against defects in materials and craftsmanship. Our technical support team is always available to assist with charging parameters, pack layout recommendations, and safety practices.

Usage & Safety Guidelines

• Use a dedicated lithium-ion smart charger supporting CC/CV charging mode up to 4.20V.
• Never charge above 4.25V per cell or discharge below 2.50V per cell.
• Never exceed the maximum continuous discharge current of 6A (6000mA).
• Always inspect cell outer shrink wrap, insulator ring, and terminals for damage before use; rewrap immediately if damaged.
• Never carry loose 18650 batteries in pockets, bags, or purses with metal objects like keys or coins; practical storage in an insulated battery case is essential.
• Do not short-circuit, crush, incinerate, puncture, or submerge cells in water.
• Store batteries at 3.60V–3.85V per cell in a cool, dry, well-ventilated location away from direct sunlight.
• When building multi-cell packs, always integrate a quality Battery Management System (BMS) with over-current, over-charge, over-discharge, and thermal balance protection.
