Power up your portable electronics with this 2-pack 505060 2000mAh rechargeable Li-Polymer battery set. Perfect for makeup mirror lights (网红灯), LED lighting fixtures, smart home devices, e-book readers, hand warmers, camping lights, Bluetooth speakers, and various DIY electronic projects requiring 3.7V power supply. Each battery delivers factory-rated 2000mAh capacity for extended runtime — a makeup mirror can run for hours on a single charge.
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, and short circuit protection. 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. The ultra-thin 5mm profile fits perfectly in space-constrained devices.
Compatibility Note: Fits devices that use 505060 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: 5mm thickness × 50mm width × 60mm length — measure your battery compartment to ensure proper fit. Suitable for DIY electronic products with power consumption less than 7.4Wh. Not suitable for high-power power tools or model aircraft.
Installation Tip: If your original battery has a connector (JST PH-2P or Molex), 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 (red to red, black to black). Always verify polarity before soldering and do not reverse the connection — reversing polarity can damage both the battery and your device.
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 (5V USB charger typically works with the device’s charging circuit). Store in cool, dry place when not in use (recommended storage temperature: -10 to 45°C).

🔋 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.
