Panasonic Lithium Coin batteries are long lasting and reliable. The high energy density of Lithium Coin batteries and their high nominal voltage of 3V make them ideally suited for use in all kinds of products where the trend is to achieve increasing miniaturization. Ideal for appliances such as laser pointers, medical devices, heart rate monitors, calculators, small remote controls such as car keys, bike computers, kid's toys and similar appliances. Panasonic Lithium Coin batteries are superior in terms of leakage resistance under environmental changes compared to other types of batteries. This is due to the use of organic electrolytes that have a solidifying point which is much lower than the aqueous solution electrolytes used in other types of batteries. Even under heat shock, which constitutes the severest challenge for batteries, the batteries achieve stable characteristics under high temperature and humidity conditions. The Panasonic&rsquo;s Lithium Coin batteries have been designed to provide reliable and long-lasting power. A long shelf life of up to 10 years. Reliable even in a wide range of operating temperatures (-30&deg;C to+60&deg;C). Wide range available on blister. Extensive cross reference table on the blister. No mercury added.
