🔋 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 router with this NBL-43A2300 2300mAh replacement battery. Designed for the TP-Link Neffos TP703A — a compact 3G wireless router that converts a 3G data connection into a portable Wi-Fi hotspot, perfect for travel and outdoor use. The TP703A features a Micro USB power interface, supports 150Mbps wireless transmission, and works with China Telecom (CDMA2000), China Unicom (WCDMA), and China Mobile (TD-SCDMA) 3G data cards. This Li-ion battery delivers the factory-rated 2300mAh capacity, providing extended runtime for your on-the-go internet needs.
Built with high-quality Grade A Li-ion cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS certified for safe transport and use. The battery supports 5V/1A or 5V/2A charging via Micro USB — you can charge it using the same power adapter that powers the router, or any standard USB charger. With a cycle life of over 500 full charge cycles maintaining 80% capacity, this replacement battery is designed for long-term durability. For reference, third-party retailers sell this battery for approximately $16 to $30.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches NBL-43A2300. Also compatible with TP-Link Neffos C5s TP704A, TP704C, C5A, and C5A Dual SIM. This is a universal router battery replacement — professional installation is not required. The battery is user-replaceable — just open the back cover of the TP703A router, remove the old battery, and insert the new one with the correct polarity.
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 or 5V/2A USB charger. If you don’t use the battery for a long time, store it in a dry and cool place and charge it fully once every three months to avoid shortening its battery life. If you notice swelling or overheating, stop use immediately.
