How does testing internal resistance help predict when a UPS battery will fail?

Internal resistance increases as batteries age and degrade; high internal resistance indicates the battery can no longer supply the current needed, making it time to replace the pack.

What does ripple voltage measurement reveal about backup power system health?

Ripple voltage shows how well the charger is maintaining clean DC power; high ripple indicates aging charger or battery problems that reduce equipment runtime during a power failure.

Why would a data center monitor discharge capacity regularly?

Discharge capacity reveals how long the UPS will actually run the servers when mains power fails; declining capacity over time shows the battery pack is degrading and may not protect during an outage.

How do configurable pass/warning/fail thresholds make battery maintenance easier?

Custom thresholds let you flag batteries for replacement before they reach critical failure, reducing emergency downtime and allowing planned maintenance during scheduled downtime.

Can the Meter and Sequence modes test a complete UPS system of multiple batteries?

Yes, Sequence mode walks through each battery in a multi-battery string, recording results for the entire pack in one operation, which is essential for large backup power systems.

Is this analyzer suitable for maintaining emergency backup systems in hospitals or banks?

Absolutely; mission-critical facilities depend on routine battery testing to ensure the backup system will function when needed—this analyzer automates that critical maintenance.

Fluke BT508 Battery Analyzer

Name: Fluke BT508 Battery Analyzer
Brand: Fluke
SKU: Fluke-BT508

The Fluke BT508 Battery Analyzer tests internal resistance, ripple voltage, and discharge capacity with configurable pass/warning/fail thresholds. Meter and Sequence modes support both quick checks and structured maintenance of multi-system battery strings.

Overview

The Fluke BT508 is part of the Fluke 500 Series Battery Analyzers and is designed for systematic testing and maintenance of battery strings in UPS systems, data centers, and critical power infrastructure. It measures battery internal resistance, voltage under load, ripple voltage from DC charging circuits, and discharge characteristics, delivering objective pass/warning/fail results based on user-configurable thresholds. Meter and Sequence modes serve both rapid single-battery checks and structured multi-system maintenance routines, with full data management and reporting via Fluke Battery Management Software.

Key Features

Internal resistance test simultaneously measures battery voltage during each test
Discharge mode collects voltage at user-defined intervals to calculate capacity loss and time to cut-off voltage
Ripple voltage test detects AC components in DC charging circuits that accelerate battery deterioration
Meter mode for quick troubleshooting with save and recall of readings in measurement or time sequence
Sequence mode for structured maintenance across multiple power systems and battery strings
Up to 10 configurable threshold sets with pass/warning/fail indication after each measurement
Intercell strap resistance test measures connections between individual batteries in a string
Compatible with Fluke Battery Management Software for historical strap resistance reporting and trend analysis
AutoHold automatically captures a stable reading after one second of stable measurement

FAQ

What types of batteries can the BT508 test?
The BT508 is designed for lead-acid battery strings commonly found in UPS systems, data centers, and industrial backup power installations. It tests internal resistance, ripple voltage, and discharge behavior for these critical applications.

What is the intercell strap resistance test?
This test measures the electrical resistance of the connections between individual batteries in a string. Elevated strap resistance indicates a degraded connection that can reduce overall battery system performance and reliability.

Is this product still available?
The BT508 is discontinued. Contact Procure.ae to request a quote on available stock or to receive a recommendation for the current Fluke battery maintenance solution that meets your requirements.
