Product Description
Overview
Model 906R24BNBAO is an inexpensive, one piece, easy to install battery fuel gauge. It is completely solid state and provides a reliable, accurate, and easy to read display of battery state-of-charge. Model 906R24BNBAO is equipped with a round case and a printed circuit board mounted module for custom dash panel applications.
- The Output Signal option causes the voltage on pin 3 to drop from 5 to 0 volts at 80% discharge. It can be used to signal another component or to allow for the disabling of a specified vehicle function, insuring against abusive deep discharge conditions. The Output Signal can also be used to drive the CURTIS 1178 Relay Module.
- Special models and custom panels are available. For more details, please see the 906 Meter Datasheet (PDF format).
Specifications
- Manufacturer: CURTIS

Features include:
- All principal circuits are integrated in a single chip for long-life reliability.
- A 10-bar LED displays the state-of-charge successively, bar by bar, from full to empty.
- At 70% depth of discharge, a flashing LED signals an "energy reserve" alert.
- At 80%, alternately flashing LEDs provides an "empty" status warning.
- Model 906R24BNBAO is compact and easily installed in panel cutouts as small as Ø 52.4 mm, with as little as 35 mm behind panel clearance needed.
- Recognizes improperly charged battery.
- Keyswitch activated LED display (state-of-charge is monitored as long as 906 is connected to battery).
- Memory allows gauge to recall state-of-charge whenever battery is disconnected.
- Three possible reset methods:
- Open Circuit Reset (OCR): Upon reconnection of a battery the gauge will reset if it measures 2.09 volts/ cell or higher (example "B" profile) (for units with memory option).
- High Voltage Reset (HVR): Gauge must measure >2.35 volts per cell for 6 continuous minutes during charging (example "B" profile).
- Charge Tracking Reset (CTR): Display tracks charge level during opportunity charging (requires gauge to be connected to battery when charging).
