✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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.

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.

Compatible devices include driving recorders (dash cams), mosquito repellent lamps, LED lights, pet water feeders, dust mite removers, smart home sensors, wireless mice and keyboards, small medical devices, and various DIY 3.7-5V electronic projects. The replacement battery for mosquito repellent lamp with 603048 model is a common size for many portable insect repellent devices. Before ordering, please check your original battery model is 603048 or measure your battery compartment dimensions — it should be approximately 6mm thick, 30mm wide, and 48mm long. This 1000mAh rechargeable Li-Polymer battery with protection board is not suitable for high-power devices like power tools, drones, or model aircraft.

The 603048 1000mAh 3.7V Li-Polymer battery has a typical capacity of 1000mAh (3.7Wh) and nominal voltage of 3.7V. Charge limit voltage is 4.26V, discharge cut-off voltage is 2.75V. Battery dimensions are 6 x 30 x 48mm, weight is 14.5g per battery. Standard charge and discharge current is 0.5C (500mA). Operating temperature range: charge 0-45°C, discharge -20 to 60°C. This 603048 battery specs include built-in PCM protection board with 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:5]. Cycle life is 500 cycles maintaining 80% of original capacity. Connection: red wire positive (+), black wire negative (-) — no connector included.

Installing 603048 battery in driving recorder or mosquito repellent lamp is straightforward for devices with replaceable batteries. First, turn off and disconnect your device from power. Open the battery compartment or disassemble the device to access the old battery, carefully noting the connection polarity — red wire positive (+), black wire negative (-). Disconnect the old battery. If your original battery has a connector (such as JST), you have two options: Option 1: Desolder or cut the old battery wires and solder the new 603048 battery wires following the same polarity, using heat shrink tubing for insulation. Option 2: Cut the connector from the old battery (keep at least 5cm of wire attached) and solder it to the new battery wires — red to red, black to black — then insulate with heat shrink[reference:6]. Never reverse the polarity as this can damage the device or battery. After installation, reassemble the device and charge fully before first use. If you are not comfortable with soldering, professional installation is recommended.
