Batteries

• Only use rechargeable batteries
• Use Gigaset provided batteries, as they are tested for optimum usage in DECT handsets
• Charge the batteries fully prior to first use

When you replace the Gigaset provided batteries:

• Only use rechargeable batteries
• Batteries with a capacity > 750mAh normally have a poor cycle-life and are not recommended for DECT-applications.

High voltage protectionPrimary-cell detection

The integrated high voltage protection Primary-cell detection detects if during charging the battery voltage does not exceed the 3.3 V. If high voltage is detected, the handset will stop charging until you take the handset out/in the charger or when the handset reboots due to no power. This is mainly caused by high impedance or wrong type of the batteries (Non-rechargeable, Low quality, old or damaged batteries)

Charge debouncer

The charging debouncer avoids:

• The handset restarts charging when the "table is bounced"
• Handset is in charger and ringing, user takes handset out of charger to answer call and short out/in charger is detected that ends the call

The handset must be removed for 1 second from charger to recognize out-of-charger event. shorter out-of-charger events are suppressed.
