Carbon 7 batteries
Battery Model: AA / AAA batteries carbon
Standard Voltage: 1.5V
Battery Size: 10.5 * 44.5mm
Introduction: Carbon and the domain name on the 7th battery R03P AAA batteries or battery discharge time: 40min or more (load 3.9Ω, 24h / d even put to 0.9V, test temperature 20 ± 20 ℃, relative humidity of 60 ± 15%) (test Article pieces: 20 ± 2 ℃, RH60 ± 15%, 75Ω4h / d, EPV = 0.9V) is mainly used for: remote control, radio, digital cameras, watches, flashlights, electric toys, mouse, alarm, electric toothbrushes, medical consumer electronics.
1、Carbon-7 cell composition and process characteristics: manganese, electrolyte, zinc and copper, apron, isolation, manganese, etc.: the use of advanced leak fluid technology, with excellent wear resistance, high temperature materials, suitable temperature as well as a wide range of fluid leak-proof performance, long life, high safety, no explosion, no fire and so on.
2, the carbon on the 7th Battery performance standards: battery technology requirements and dimensions should meet or greater than GB / T 8897.1-2008 and GB 8897.2-2008. Shelf life: 3 years (at 20 ℃ ± 2 ℃, relative humidity of 60 ± 15% Storage Article under conditions).
3, the carbon on the 7th battery Packing: steel packaging, PVC packaging, can provide OEM OEM service.
Note:
One, since the carbon on the 7th Dry cell is a non-rechargeable, so forced charging will cause leakage or risk of damage to the equipment.
Second, the battery "+, -" pole should be in accordance with the required direction using the device is installed correctly.
Third, prohibit short, heat, burning and open the battery.
Fourth, the battery Operating temperature: -10 ℃ - +60 ℃; Storage temperature: -10 ℃ - +45 ℃
