We want to know exactly
We also test our energy storage systems beyond the prescribed product tests to give you maximum safety. We wanted to know: What happens if a charged VARTA.wall battery cell is damaged? The result: The safety mechanisms of the VARTA.wall worked perfectly - the damage was limited to the affected cell, the rest of the battery was not overloaded.
