10.8.4 Back-up cycle, battery capacity
A back-up cycle is limited to 15 minutes. On expiry of this time, the KeTop
is switched off completely.
The back-up battery capacity is designed for 4 cycles without having to
recharge the back-up battery in the meantime.
In order to prevent a deep discharge of the back-up battery, the KeTop is
switched off before expiry of the back-up time if the back-up battery
reaches a critical capacity level.
10.8.5 Safety notes
The back-up battery is a lithium ion battery for which the following safety
notes apply:
ATTENTION!
• Charge the back-up battery only via the KeTop
•
Do not immerse lithium ion batteries in water:
If the hermetic seal of the lithium ion battery is defective, the Li ion cell
will react very violently with water.
•
Preferably use sand to extinguish burning Li ion batteries; do not use
water!
•
Li ion batteries are sensitive to mechanical shocks!
They can ignite as a result of an internal short-circuit (e.g. caused by
crushing) and in contact with air.
•
Do not:
Heat, burn, short-circuit or dismantle Li ion batteries!
10.8.6 Disposal of the back-up battery
NOTICE
• The back-up battery is special waste and must be disposed of in the
prescribed manner.
•
Although the back-up battery has a low voltage, it can give off enough
electricity in the event of a short-circuit to ignite inflammable materials.
It therefore must not be disposed of together with conductive materials
(such as e.g. iron chips, oil-contaminated wire wool, etc.).
10.8.7 Technical data
