With the proliferation of Lithium-Ion (Li-ion) batteries in telecom infrastructure, the safety profile of energy storage has changed. Issue 5 addresses the unique safety risks associated with Li-ion batteries compared to traditional Valve Regulated Lead Acid (VRLA) batteries. This includes more specific guidelines on how these batteries should be housed and tested for thermal runaway scenarios. gr-63-core issue 5 pdf
