BAT120000100 US Version: This exact order code is the BAT120 package supplied with a US power supply. It is intended for North American installations that require the BAT120 together with a compatible AC-to-DC adapter rather than the UPS hardware alone.

Uninterruptible Power Operation: During normal operation, the BAT120 passes the incoming 9–30 VDC supply through to the connected device. If external power is lost, the internal battery automatically provides a regulated 12 VDC output to help keep the connected Teltonika device operating.

Maximum Battery Output: Battery-mode output is limited to 22 W / 1.8 A. The connected device and any attached accessories must remain within this power limit when operating from battery backup.

Backup Time: Teltonika advertises operation for up to approximately six hours, but actual runtime depends heavily on the connected device, cellular activity, Wi-Fi usage, Ethernet traffic, peripherals, battery condition, charging state, and ambient temperature.

Current Battery Capacity: Current Teltonika BAT120 documentation lists two 18650 Li-ion cells with a total capacity of 2600 mAh / 17 Wh. Earlier BAT120 documentation may show a different mAh rating while retaining the same 17 Wh energy specification, so buyers with production-revision requirements should confirm the exact hardware batch.

Charging Revision: Teltonika specifies up to 9.5 W / 800 mA maximum battery charging current beginning with Batch 26. Earlier Batches 1–25 use a maximum charging specification of 4 W / 300 mA.

Compatible Device Power: Compatibility should be checked against both the physical 4-pin connector and the connected device's voltage and power requirements. In battery mode, the attached equipment must be able to operate from the BAT120's 12 VDC output and remain within the 22 W / 1.8 A maximum.

Compatible Teltonika Families: Teltonika's current BAT120 material lists compatibility with supported devices in the RUT2xx, RUT95x, RUT3xx, RUTXxx, TRB14x, and TRB2xx families as well as TSW110 and TCR100. Compatibility should still be confirmed for the exact product model and hardware configuration.

4-Pin Power Connections: The BAT120 uses separate 4-pin industrial DC connectors for power input and power output. It is not an AC UPS with conventional wall-style AC outlets; it is specifically designed to provide DC backup power to compatible networking equipment.

Input Voltage: The BAT120 accepts 9–30 VDC. Teltonika recommends using a stable, high-quality power source and warns that poorly regulated higher-voltage supplies can generate voltage spikes beyond their nominal output.

Input & Output Protection: Reverse-polarity and overvoltage protection are provided on the input, while the output includes 3 A overcurrent protection to help protect the UPS and attached equipment from common power faults.

Alarm Output: An active HIGH alarm output is available for compatible monitoring and automation applications. This allows the BAT120 to be integrated into installations where changes in power state need to trigger alerts or other actions.

Operating Temperature: Unlike many Teltonika routers that support wider industrial temperature ranges, the BAT120 is specified for operation from 0°C to 45°C because of its integrated lithium-ion battery system. Installation temperature should therefore be considered carefully in outdoor cabinets, vehicles, and unconditioned industrial environments.

US PSU Included: BAT120000100 includes a 24 W US power supply with a 4-pin connector. Buyers who already have an appropriate power source or require a different regional power adapter should confirm whether another BAT120 package configuration is more appropriate.

Best Fit: The BAT120000100 is a strong choice for MSPs, system integrators, industrial operators, retailers, utilities, transportation organizations, security installers, and remote-site operators that need compact DC battery backup for compatible Teltonika networking equipment and want the US power supply included with the package.
