Also permanent charging exceeding the limits of specified temperature ranges may reduce the battery life. The maximum life is achieved, when charging at an average temperature of +20 to +30˚C. Discharging The specified temperature range is from -20 to +60˚C on discharge. Repeated discharge at the extreme temperatures may affect battery life. In all application do not deep-discharge (< 0.6 V / cell) our Ni-MH cells and batteries. Life Expectancy in Long-term use Batteries are chemical products involving chemical reactions. Hence capacity and voltage will decrease over long time use as well as during long-term storage capacity and voltage will drop. Typically, a battery will last 5 years or 1000 IEC cycles, if used under recommended conditions and not overdischarged or overcharged. However, non-observance of recommended conditions concerning storage, charging, discharging, temperature and other factors during use can lead to shortened life expectancy of products and deterioration of performance. Severe use applications Short term use of Ni-MH batteries outside specified ranges maybe possible. Please consult us, if such a requirement exists. DESIGN INFORMATION SAFETY GUIDELINES

Keep out the reach of children. If swallowed, contact a physician at once
Do not incinerate or mutilate, may burst or release toxic materials
Do not short circuit, may cause burns
Do not deep-discharge into reserve
Do not solder on the battery directly (use our tagged versions)
Restrict charging current and time to the recommended value
Observe charging temperature: 0 to +65˚C / +85˚C
Battery compartment should provide sufficient space for battery to expand in a case of abuse
Either battery compartment or battery connector should have a design that makes it impossible to place the battery in reverse polarity
Equipment intended for use by children should have tamper-proof battery compartment
Battery of different electrochemical system, grades, or brands should not be mixed
Battery disposal method should be in accordance with local and state regulations
