About Fluke Battery Testers
Fluke Battery Testers are specialised instruments designed for the maintenance, troubleshooting, and performance assessment of individual stationary batteries and battery banks across industrial, commercial, and critical power applications.
Key Measurements
- Battery Resistance: Assesses the internal resistance of batteries, which can indicate potential issues affecting performance.
- DC and AC Voltage: Measures both direct and alternating current voltages to ensure batteries operate within specified parameters.
- DC and AC Current: Evaluate the current flow to and from the battery, aiding in performance analysis.
- Ripple Voltage: Detects unwanted residual periodic variations in the DC voltage output, which can affect sensitive equipment.
- Frequency: Monitors the frequency of AC signals associated with the battery system.
- Battery Temperature: Utilises integrated infrared temperature measurement systems to monitor battery temperature, as excessive heat can indicate or cause problems. Models like the BT521 provide precise thermal readings alongside other key battery diagnostics.
Where Are They Used?
Fluke battery testers are used in a variety of settings, including:
- Automotive: Testing car batteries, including lead-acid batteries in traditional vehicles and lithium-ion batteries in electric vehicles (EVs).
- Telecommunications: Ensuring backup batteries in telecom towers and data centres are reliable.
- Industrial: Maintaining batteries used in forklifts, uninterruptible power supplies (UPS), and other heavy machinery.
- Consumer Electronics: Testing batteries in laptops, smartphones, and other portable devices.
