Connection Terminal Specifications for Lithium Batteries and Key Circuit Design Points
Connection Terminal Specifications for Lithium Batteries and Key Circuit Design Points When choosing batteries, the rating of the device, operating load conditions, and operating temperature range should be considered. Also, when deciding connection terminal configuration, battery installation space and battery fixation method should be considered. Refer to the lithium battery section of the battery selection guide (p12).

〔Primary Lithium Batteries for Memory Backup ― Key Design Points〕 〕 ● Selecting Batteries When considering the relationship between load current and battery durability, please keep in mind that you must select the appropriate battery to meet load, current and expected durability of the equipment. The operating voltage of primary lithium batteries tends to decrease as the temperature decreases. The current consumption of ICs tends to lessen as the temperature decreases.
When the battery is placed close to components that generate heat, the battery may become hot. This may cause deformation of the gasket material, resulting in leakage and inferior performance. ● Soldering When soldering is required, use a battery equipped with a connection terminal. Do not apply solder directly to the battery. Hand soldering should be done as quickly as possible (within 5 seconds) at a temperature from 250℃ to 350℃.
〔Rechargeable Lithium Batteries〕 〕 As part of our ongoing efforts to meet customers' needs, we offer a wide range of batteries featuring different terminals, as well as battery holders that facilitate easy connection to equipment. Only standard types of assembled batteries are discussed in this catalog. Consult Sanyo for details regarding terminals and other types of assembled batteries. The ML2430,ML2020,ML2016,and ML1220 are not nickel-plated.

〔Battery Handling Precautions for Your Own Safety〕 〕 Lithium batteries contain combustible materials such as lithium metal and organic solvent. Improper handling can lead to heat generation, bursting or fire. To prevent accidents, follow these precautions and refer to them when precautions regarding lithium battery usage are described in instruction manuals for equipment you are using. ●Coin-type Primary and Rechargeable Lithium Batteries Warning! 1. Do not charge. (Primary batteries, CR series).
●Cylindrical-type Primary Lithium Batteries Warning! DO NOT CHARGE 1. Do not use batteries for unspecified purposes. Differences in voltage or terminal configuration may cause an imperfect connection, fire, heat generation, leakage or bursting. 2. Do not charge. When this battery is charged, gas is generated inside and raises internal pressure, resulting in fire, heat generation, leakage or bursting. 3. Do not heat, disassemble nor dispose of in fire.
〔Precautions for Designing Equipment〕 〕 As specified in these Battery Handling Precautions for Your Own Safety, improper handling of lithium batteries can lead to overheating, bursting or fire. To prevent accidents, carefully observe the following precautions when designing equipment. ●Primary Lithium Batteries [for main power source] Caution! 1. Select appropriate batteries for specific uses.
