Battery & Tech
Test It. Understand It. Bring It Back to Life.
Battery & Tech — Battery Testing, Cells, Chargers and Electronics
Behind every cordless battery pack are cells, electrical connections and a battery management system working together to deliver power safely. Understanding these components is the key to diagnosing faults across all four groups in The Range.
The right test equipment helps you measure what is happening rather than guess. Learn how to check battery voltage, understand charger behaviour, interpret BMS symptoms and investigate common faults.
Explore battery testing, cell layouts, charging systems and repair equipment to build your knowledge before deciding whether to repair, rebuild or replace a pack.
