🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Manufactured with Grade A Li-ion cells and equipped with multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS, UN38.3, and ISO9001 certified for safe transport and use. The DZ09 LQ-S1 battery replacement features a compact 5.2×31×24mm form factor — designed to be a direct drop-in fit for most universal smart watch battery compartments. The battery has a cycle life of 500+ full charge cycles when properly maintained. Operating temperature range: charge 0-45°C, discharge -20-60°C.
Installation Tip: Most compatible smart watches feature a removable back cover — no tools are required. Simply open the back cover, disconnect the old battery’s connector, and plug in the new LQ-S1 battery. Always verify polarity (red wire positive “+”, black wire negative “-“) before connecting. The watch is not water resistant, so no special sealing is required after replacement.
Battery Care Tips: Avoid full discharge — recharge when battery level drops below 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best performance, use a standard 5V/1A USB charger. If you don’t use the watch for a long time, store the battery in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.
