The company was founded in 1954 and has been focusing on the research and development of small batteries and non-rechargeable batteries. It has now become the top brand of non-rechargeable batteries in China. The company is a national key technology center, equipped with a provincial key laboratory for batteries, and also has a testing center certified by CNAS.
A: No, CR2032 batteries are primary lithium manganese dioxide (LiMnO2) batteries and are non-rechargeable. Attempting to charge them may cause leakage or damage.
A: Under proper storage conditions (20±5°C, 55±20% relative humidity), these batteries have a long shelf life of up to 10 years with very low self-discharge rates.
A: They differ primarily in physical dimensions and nominal capacity. For example, CR2032 has a diameter of 20mm and thickness of 3.2mm (240mAh), whereas CR2450 has a diameter of 24mm and thickness of 5.0mm with higher capacity.
A: They are designed for a wide operating temperature range from –30°C to +85°C, making them highly reliable for both indoor and outdoor electronic devices.
A: Keep them in a clean, dust-free, well-ventilated, shady, and dry environment. Store them away from heat sources and metal objects to avoid short circuits.
A: Yes, they are compliant with global environmental standards and are certified recyclable. However, they should always be disposed of through correct electronics recycling channels.
