2.2 Precautionary Measures when Handling the Rechargeable Bat-
teries
2.2.1 General
Do not dispose of rechargeable batteries in a fire.
Ensure that the battery connections cannot become shorted.
Do not open the rechargeable batteries.
If, after damage to a rechargeable battery, diluted sulphuric acid should comes into
contact with the skin or clothing, immediately wash off the skin or clothing with water. If
diluted sulphuric acid comes into contact with the eyes, immediately spray the eyes co-
piously with water and consult a doctor.
Please read the related instructions before using the rechargeable batteries.
It is recommended to replace the batteries at the latest every 3 years.
Always use the battery type recommended by Swissphone
2.2.2 Storage of Batteries
Never store the rechargeable battery near to a fire.
In general, lead acid batteries self-discharge approximately 3% to 5% per month. The
discharge curve of the used pbq 12-12 batteries remains relative flat until 20% has
been discharged, after which the discharge rate increases. It is not advisable to permit
a self-discharge level below 60% of the capacity. When no load is connected and the
battery has a 60% capacity its voltage is approximately 12.6V. When this condition is
reached, recharge the battery.
In general, stocked batteries should be measured and recharged at least every 6
months. Recharge the batteries as soon as possible if they become discharged.
If a battery is not to be used for a long period, store it in a cool location where the tem-
perature will not fall below 0°C!
Do not store partly discharged batteries, as they will lose capacity. This is an irreversa-
ble process.
Note: If the ITC2100-NA is to be stored, it is recommended by Swissphone to disconnect
the battery from the ITC2100-NA in order to prevent fast battery discharge.
