The Battery Tender® Quick Disconnect USB and USB-C Voltage Indicator combines two functions in one SAE quick disconnect accessory — a real-time LCD battery voltage display and simultaneous USB and USB-C device charging at up to 3 Amps from the vehicle's 12V battery. Monitor battery state while charging devices, from the same SAE connection point.

LCD Voltage Display — Real-Time Battery Monitoring

The LCD display shows battery voltage in real time — not just a color indicator, but an actual voltage reading. Track battery state precisely during charging sessions, monitor voltage drop under load, and verify that a Battery Tender® charger is maintaining the correct float voltage. More information than LED indicators alone.

USB and USB-C Charging — Up to 3 Amps

A USB-A port and a USB-C port provide up to 3 Amps total charging output for phones, tablets, GPS units, and accessories — powered directly from the vehicle's 12V battery through the SAE quick disconnect connection. Charge devices from any vehicle with a Battery Tender® ring terminal harness installed without using the vehicle's ignition-switched outlets.

SAE Quick Disconnect — Compatible with the Full Battery Tender® System

Uses the SAE J563 two-pin connector standard, compatible with all Battery Tender® chargers and accessories. Connect to any existing ring terminal harness or SAE quick disconnect system — the voltage indicator sits inline with the connection, monitoring battery state while the USB and USB-C ports charge devices simultaneously.

Compatible With

All Battery Tender® SAE quick disconnect chargers and accessories — Junior family, Plus family, Weather Resistant, Junior Multi-Chemistry, WaveCharge Standard line, and any SAE J563-compatible equipment.
