High‑capacity lithium‑ion rechargeable battery pack for wireless Confidea FLEX units. Lithium‑ion technology ensures long service life without the charging degradation common to other battery types. An integrated microcontroller manages charging and protects against overcharge, short circuit, and overheating

A full charge takes approximately 2 hours and delivers up to 12 hours of typical operation with a Confidea FLEX G4 unit. Quick‑charge functionality enables 50% charge in 45 minutes and up to 65% in one hour. Each unit includes two battery compartments for extended runtime.

Battery packs can be charged using the Confidea CHT G4 charging tray (71.98.0046), a 1U rack‑mountable charger supporting up to 10 battery packs simultaneously. Remaining battery capacity can be checked via an integrated test button, and battery status for all connected units is monitored through the Confero web interface.
