First, the various technical parameters Product Name and range of application This specification applies only to Dongguan City Connaught Electronics Co., Ltd. of 3V button lithium - manganese dioxide battery. Product: 3V CR2032 button lithium manganese battery Applications: ① button batteries due to their smaller size, it has been widely used in a variety of micro-electronic products, ranging in diameter from 4.8mm to 30mm, thickness ranging from 1.0mm to 7.7mm ; generally used for back-up power supply of electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote control, electric toys, pacemakers, electronic hearing aids, counters, and cameras. ② button battery chemistry is also divided into two major categories of batteries and physical batteries, the most common chemical battery. They consist of an anode (positive electrode), a cathode (negative electrode) and the electrolyte solution and the like. The look of stainless steel, and as a positive electrode, its extremely negative circular stainless steel cover, between the positive and negative insulating seal rings, seal rings with nylon sealing ring except for insulation effect, but also to prevent electrolyte leakage . Many types of button batteries, most of the materials used to name, such as silver oxide batteries, lithium batteries, alkaline manganese batteries. ③ lithium manganese button battery nominal voltage is 3V, termination voltage 2V, typical operating current 0.1-0.2mA. It uses a very stable chemical properties of manganese dioxide as the cathode material, with a very high specific energy of lithium metal as the anode material. The annual average capacity of not more than 2 percent lower, long storage life. Battery semi sealed structure, safe to use. Temperature range of lithium manganese button battery can work under a large -20 to +60 degrees Celsius.

No leakage Note 2: Dimensions and performance of this product to perform IEC 60086-2: 2007 standard (ie GB / T8897.2-2008, primary batteries, Part II: Dimensions and technical requirements). Fifth, security testing laboratories Project Code Project Name experimental conditions intended use standard altitude simulation test A test cell is placed at least six hours at a pressure of not more than 11.6kPa conditions. In line with GB / T8897.4-2008, primary batteries, Part 4: Safety requirements for lithium battery in the B heat shock change -40-75 ℃ in a continuous loop 10 times, then at ambient temperature for 12 hours. C vibrating battery according to the standard requirements of a sine wave vibration. On three mutually perpendicular orientation of each fixed orientation each for 12 cycles, each bearing a total cycle time of three hours. D shock being tested battery in each of three mutually perpendicular orientations fixed orientation of each subjected to 3 shocks, a total of 18 times. Reasonably foreseeable misuse test E external short circuit when the battery reaches a temperature equilibrium in the environment of 55 ℃ after. Total resistance of the external circuit should be less than 0.1Ω, continuous short circuit to the housing temperature falls to a short-circuit at least another 1 hour 55 ℃. And then continue to observe six hours. F heavy impact will 9.1㎏ weight from 610 ± 25 mm height for the freefall, flat on the vertical impact on battery 15.8㎜ steel bar diameter. G squeezed by a vise or applying pressure with a cylindrical piston of the hydraulic cylinder, from the initial 1.5㎝ / sec speed until 13KN pressure to release the pressure immediately. H forced discharge Forced discharge after the battery is connected in series with a 12V DC power supply, the battery reaches a predetermined maximum discharge current. I Abnormal Charge the battery reversely with a DC power supply connected, subjected to 3 times the charging current Ic value (Ic value specified by the manufacturer). J free fall from a height of fall of the battery on a concrete surface, dropping 6 times, about an hour after the observation.
