1.5V Nimh Aa Rechargeable Batteries
Nimh battery reconditioning charger,Generally, the NiMH rechargeable batteries rarely leak, unlike alkaline batteries.By this logic, nickel-metal hydride batteries may explode. The principle of explosion is that the air pressure inside an object becomes too large, so the container cannot be contained.
Description
Description
Nimh rechargeable battery pack,To recondition a rechargeable battery: First discharge the battery completely through normal use - using in a device such as a camera, toy or torch to the point where the device does not work. Then, fully recharge the battery (avoiding super-fast chargers) as normal.

Safety standard:
The safety standard is based on the protection of the life and property of users. It has made strict regulations on the insulation and flame retardance of raw materials for power adapter and electronic and electrical products. The products that meet the safety specifications not only require the products themselves to meet the safety standards, but also require the manufacturers to have perfect safety production, Quality assurance system. International standards include many safety standards such as IEC 62368 / IEC 61558. Safety certification mainly includes the requirements of creepage distance, electrical strength, leakage current and temperature.
Anti electric strength: refers to the zero voltage between AC input lines or between AC input and casing is increased to 1500V AC or 2200v DC, no breakdown or arc
Temperature: the safety standard is very strict on electronic appliances, and the materials are required to be flame retardant. The internal temperature rise of switching power supply should not exceed 65 ℃
Leakage current: connect the ammeter in series between the live line or zero line of the power supply and the accessible metal through the isolation transformer, and the leakage current of the switching power supply shall not exceed 3.5ma under 260V AC input
Creepage distance: refers to the shortest distance between two conductive parts or between conductive parts and equipment interface measured along the insulation surface. It is emphasized that creepage distance is to prevent ignition between devices or between devices and ground, threatening personal safety
Due to the long application time of safety certification, there are also strict restrictions and requirements. For example, CCC certification in China, not only the products submitted for inspection should comply with CCC standards, but also the factories should have relatively perfect quality assurance system (similar to ISO9000 audit) to ensure the quality of products in mass production, Each product meets the requirements of CCC; Not only that, but also accept the regular and irregular quality supervision and inspection of CCC
