- Varta expands factory for lithium coin cell production
- Revenue boom for battery maker despite Covid-19
The F-Version was developed primarily for technological applications such as health monitoring and controlling devices that are worn directly on the body or on the skin and are always or have always to be in operation.
In vibration tests the cells are shaken with different frequencies with up to 1 hertz/minute. The cells are overcharged for 12h under extreme current and voltage conditions and discharged below state of charge. Fully charged cells are crushed with a force of 13kN and heated up to 130°C to test for safe operatation.
