Specification

Applications

• Telematics Box (T-Box): Providing backup power and main power for data transmission, GPS positioning, and vehicle status monitoring .

• On-Board Diagnostics (OBD): Powering OBD modules for vehicle data reading and diagnostics .

• Emergency Call Systems (e-Call): Ensuring reliable power for emergency communication systems in vehicles .

• Other Vehicle-Mounted Electronics: Supporting various in-vehicle sensors, tracking devices, and infotainment systems .

Warnings & Precautions

Charging

• Use a NiMH-Specific Charger: Always use a charger designed for NiMH chemistry and configured for this battery's voltage (4.5V) and current limits.

• Avoid Overcharging: While NiMH batteries are somewhat tolerant, excessive overcharging can damage them. Use chargers with proper termination methods (e.g., -ΔV, timer) for fast charging .

• Temperature Monitoring: Charge only within the specified temperature range (-20°C to +60°C or as per manufacturer's specs). Charging outside this range can reduce capacity and cause damage .

Discharging

• Avoid Deep Discharge: Avoid discharging the battery pack below the cut-off voltage of 3.0V repeatedly, as this can shorten its lifespan .

• Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to +85°C). Extreme cold can reduce performance; extreme heat can accelerate aging .

• Prevent Short Circuits: Never allow the positive (+) and negative (-) terminals to connect directly. Short circuits can cause very high currents, leading to overheating, damage, or fire.

Storage

• Partial Charge Storage: For long-term storage, it is often recommended to store NiMH batteries at a partial state of charge (around 40-60%) in a cool, dry place .

• Cool and Dry Environment: Store within the specified temperature range (-40°C to +85°C) away from direct sunlight and moisture .

• Regular Checks: If stored for extended periods, check the voltage periodically and recharge if necessary to prevent over-discharge.
