Dominic Dupuis

Robert Anderson

TELUS is Canada’s fastest-growing national telecommunication company. With $12.0 billion of annual revenue and 13.7 million customer connections, they rely on a large number of batteries, of which about 1200 are 2-volt VRLA's. Extending the lives of these assets and reducing premature failures are key to fueling network growth. This paper discusses the catalyst rehydration procedure as a safe and practical method of extending the useful life for about 240 strings in the TELUS network.
