**Classification: Chemical System: Nominal Voltage: Typical Capacity:** "Lithium Coin" Lithium / Manganese Dioxide (Li/MnO2) 3.0 Volts 58 mAh (to 2.0 volts) (Rated at 30K ohms at 21°C) 1.3 grams (0.04 oz.) 0.3 cubic centimeters (0.02 cubic inch) 1 microampere 129 milliwatt hr/g, 561 milliwatt hr/cc 0.017 grams (0.0006 oz.) MH29980 -30C to 60C ~1% / year **Typical Weight: Typical Volume: Max Rev Charge: Energy Density: Typical Li Content: UL Recognized: Operating Temp: Self Discharge:** ## **Safety** : **(1) KEEP OUT OF REACH OF CHILDREN.** Swallowing may lead to serious injury or death in as little as 2 hours due to chemical burns and potential perforation of the esophagus. **Immediately see doctor; have doctor phone (202) 625-3333.** **(2) Battery compartment design** . To prevent children from removing batteries, battery compartments should be designed with one of the following methods: a) a tool such as screwdriver or coin is required to open battery compartment or b) the battery compartment door/cover requires the application of a minimum of two independent and simultaneous movements of the securing mechanism to open by hand. Screws should remain captive with the battery door or cover. ## **Internal Resistance Characteristics** Pulse Test at 21°C (70°F) **Bkgnd Drain:** Continuous 30K ohms 0.097 mA @2.9V **Pulse Drain:** 2 seconds X 12 times/day 400 ohms 6.8 mA @2.7V **==> picture [265 x 111] intentionally omitted <==** **----- Start of picture text -----**
