Direct replacement for specific router models
The KingSener 515060AR-2100 is a 3.8V 2100mAh lithium-ion battery built to replace the original power cell in compatible TIANJIE 4G LTE routers. It matches the B9010, MG905, MG906 and B803 part numbers and delivers a rated 7.98Wh capacity for portable networking devices.
Verify the original battery code
Before ordering, remove the existing pack and confirm the model printed on its label matches 515060AR-2100 or one of the listed part numbers. Compare the physical dimensions and connector position with the product images to ensure the replacement fits the router's battery compartment correctly.
Steady output during continuous router operation
Under sustained load the cell maintains stable voltage while the router manages active 4G LTE connections and Wi-Fi traffic. The supplier notes the full charge capacity meets or exceeds the 2100mAh design rating, and advises an initial conditioning cycle of two to three full charge and discharge rounds for optimal long-term runtime.
