The IBAR is a handheld tester that assesses the condition of stationary batteries by measuring their internal resistance, the cell voltage and the resistance of the inter-cell connections. It works on batteries taken fully offline, disconnected from the charger and the load, and stores every measurement to track the evolution of the bank.
Advantages
Fast, repeatable readings
With the included pin probes each reading takes about two seconds and is free of rectifier ripple, because the battery is disconnected: values are comparable between inspections.
Automatic verdict
Thresholds or tolerance ranges are defined and the device flags each cell as PASS, WARNING or FAIL during the test itself, with automatic resistance range detection.
Genuinely light
It weighs 0.5 kg, runs on a rechargeable Li-Ion battery and is operated with one hand: made to walk complete battery rooms without fatigue.
A history that anticipates failures
Internal resistance grows with ageing before the voltage reveals the problem; its trend over time points out the cells to replace.
Applications
- Periodic inspections of stationary batteries in substations, UPS, telecom and data centres.
- Flooded lead-acid, VRLA, nickel-cadmium and lithium batteries.
- Detection of loose or corroded inter-cell connections.
- Acceptance tests and commissioning of new banks.
- Support during capacity tests by measuring each cell voltage.
About the product
The resistance range spans 0 to 5 Ω in four scales with resolution from 1 µΩ, and the voltage range reaches ±60 V. The combined U+R mode measures voltage and resistance in a single pass, and the internal memory keeps every reading with time and date. With the DV-B Win software, per-cell trends are built and reports generated in PDF, Word or RTF.
Accessories: straight or angled pin probe sets, zero calibration board, mains adapter, transport case and PC software included.

Frequently asked questions
Why measure internal resistance and not just voltage?
Because a cell can show a normal voltage and still be degraded; internal resistance grows with ageing and anticipates the failure much earlier.
Does the battery have to be disconnected?
Yes. The device is designed for offline batteries, disconnected from the charger and the load, which removes interference and makes measurements repeatable.
How do I know a cell is bad?
By defining thresholds in advance: during the test each reading is automatically compared and flagged PASS, WARNING or FAIL.
Can I compare measurements from different campaigns?
Yes. All readings stay in memory with time and date, and the PC software builds per-cell trends to compare them between inspections.
