Maxell, Ltd. Energy Division Heat Resistant Coin Type Lithium Manganese Dioxide Batteries (CR) / Coin Type Lithium Manganese Dioxide Batteries (CR) Safety Instructions This battery contains lithium, organic solvents, and other combustible materials. For this reason, improper handling of the battery could lead to distortion, leakage*, overheating, explosion, or fire, causing bodily injury or equipment trouble. Please observe the following instructions to prevent accidents. (* Leakage is defined as the unintentional escape of a liquid from a battery.) Warnings — Handling ■Keep battery out of reach of children. Swallowing can lead to chemical burns, perforation of soft tissue, and death. Severe burns can occur within 2 hours of ingestion. If swallowed, seek medical attention immediately. ■Never charge. The battery is not designed to be charged by any other electrical source. Charging could generate gas and internal short-circuiting, leading to distortion, leakage, overheating, explosion, or fire. ■Never heat. Heating the battery to more than 100 deg. C* could increase the internal pressure, causing distortion, leakage, overheating, explosion, or fire. (* Consult Maxell regarding heat resistant coin type lithium manganese dioxide batteries.) ■Never expose to open flames. Exposing to flames could cause the lithium metal to melt, causing the battery to catch on fire and explode. ■Never disassemble the battery. Do not disassemble the battery, because the separator or gasket could be damaged, leading to distortion, leakage, overheating, explosion, or fire. ■Never reverse the positive and negative terminals when mounting. Improper mounting of the battery could lead to short-circuiting, charging or forced-discharging. This could cause distortion, leakage, overheating, explosion, or fire. ■Never short-circuit the battery. Do not allow the positive and negative terminals to short-circuit. Never carry or store the battery with metal objects such as a necklace or a hairpin. Do not take multiple batteries out of the package and pile or mix them when storing. Otherwise, this could lead to distortion, leakage, overheating, explosion, or fire. ■Never weld the terminals or weld a wire to the body of the battery directly. The heat of welding or soldering could cause the lithium to melt, or cause damage to the insulating material in the battery. This could cause distortion, leakage, overheating, explosion, or fire. When soldering the battery directly to equipment, solder only the tabs or leads. Even then, the temperature of the soldering iron must be below 350 deg. C and the soldering time less than 5 seconds. Do not use a soldering bath, because the circuit board with battery attached could stop moving or the battery could drop into the bath. Moreover do not use excessive solder, because the solder could flow to unwanted portions of the board, leading to a short-circuit or charging of the

Maxell, Ltd. Energy Division ■Never use different batteries together. Using different batteries together, i.e. different type or used and new or different manufacturer could cause distortion, leakage, overheating, explosion, or fire because of the differences in battery property. If using two or more batteries connected in series or in parallel even same batteries, please consult with Maxell before using. ■Never allow liquid leaking from the battery to get in your eyes or mouth. Because this liquid could cause serious damage, if it does come in contact with your eyes, flush them immediately with...

Maxell, Ltd. Energy Division A protective resistor is used to prevent the battery from being charged by large surges of current during diode failure. Please set the resistor so that the maximum current shown in the right table is not exceeded. For example, say a CR2032 battery is used in sample circuit (A) in combination with a main power source 5 volt. Since the permitted charge current is 10mA and this battery’s voltage is 3V, let the resistor be R>(5V-3V) / 10mA=0.2k ohm, meaning that at least 0.2k ohm is required. Note: If the diodes broke down, it is necessary for safety to replace them...

Maxell, Ltd. Energy Division ■Never store the battery in a hot and humid environment. Otherwise it may cause battery performance deterioration, deformation, leakage, overheating, or explosion. ■Keep contact force more than 2N. The battery voltage may be lower than intended value because of poor contact condition, please keep contact force more than 2N for suitable contact.
