## **System highlights of Ni-MH Button Cells – Robust Family – from VARTA Microbattery:** 

Excellent  overcharge capability due to patented GCE-Electrode Low self-discharge of 20% at RT after 1 year Flat and stable discharge voltage Long life – typical 500 full cycles Slim design Wide temperature range - Storage: -40˚C up to +65˚C - Discharge: -20˚C up to +65˚C - Charge 0˚C up to +65˚C 

**Electrical characteristics*:** Nominal Voltage: 2.4 V Typical Capacity: 150 mAh Maximum Discharge current: 280 mA cont. 

## **Key features:** 

Good recovery characteristics after long storage period and deep discharge 

Sealed rechargeable Ni-MH Button Cells from VARTA Microbattery can be operated in any position 

The cells complete the manufacturing process in a charged state Because of time and temperature depending self- discharge, the state of charge upon receipt can not be precisely defined. 

Before use, therefore, sealed Ni-MH cells should be recharged. 

## **Main Applications:** 

Car and home alarm applications Medical applications - pipettes Sensor Network Supply, timer, actor, sensor Smart grid, metering 

*See cell datasheet for further details **Physical characteristics:** Width: 27.0 mm Height: 12.9[+0] -1.2[mm] Length: 15.5 mm Typical weight: 12.4 g Pin Distance (P): 10.0 mm Length (L): 12.9mm Pin: 1.0 mm x 0.25mm Pin out + P L

## **PROPER USE AND HANDLING** 

## **Charging** 

Extended charging outside specified temperature ranges may have an adverse effect on cell life. 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.

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 Please refer to our material safety datasheets as supporting documents
