Power up your portable electronics with this 2-pack 603048 1000mAh rechargeable Li-Polymer battery set. Perfect for driving recorders (dash cams), mosquito repellent lamps, pet water feeders, dust mite removers, LED lights, and various DIY electronic projects requiring 3.7V power supply. Each battery delivers a stable 1000mAh capacity with an integrated protection board offering comprehensive safety features.
Manufactured with high-quality Li-Polymer cells and equipped with built-in PCM protection board. The protection features include overcharge protection (detection 4.30±0.05V), over-discharge protection (detection 2.50±0.1V), overcurrent protection (2.5±1.0A), and short circuit protection[reference:3]. With a cycle life of 500 cycles maintaining 80% capacity, these batteries offer reliable long-term performance. CE, RoHS, and UN38.3 certified for safe transport and use. Operating temperature range: charge 0-45°C, discharge -20 to 60°C.
Compatibility Note: Fits devices that use 603048 battery model with 2-wire connection. No connector included — red and black wires only, ready for direct soldering. Please verify your device’s original battery model and connection polarity before ordering (red wire = positive “+”, black wire = negative “-“). Battery dimensions: 6mm thickness × 30mm width × 48mm length — measure your battery compartment to ensure proper fit. Suitable for DIY electronic products with power consumption less than 3.7Wh. Not suitable for high-power power tools or model aircraft.
Installation Tip: If your original battery has a connector (JST or other), you can carefully cut and solder the plug from your old battery to these wires using heat shrink insulating sleeves to connect same color wires together[reference:4]. Always verify polarity before soldering and do not reverse the connection.
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. Always use a compatible charger with correct polarity. Store in cool, dry place when not in use.

🔋 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.
