no. 7 alkaline battery waterproof level, IP67 dustproof and waterproof no. 7 alkaline battery pack

Protection level, we often say IP level, dustproof and waterproof performance, the purpose is to prevent dust and water from affecting the insulation performance of the battery cells, electrical components, control system circuit boards, etc. inside the battery pack, and corroding metal devices;

If the protection level of the no. 7 alkaline battery shell does not meet the dust and waterproof requirements, the environmental conditions of the battery cells and electrical components are in an uncontrollable state. In a general working environment, excessive dust will reduce the insulation performance of electrical components. Associated with this, electrical clearance and creepage distance, systems with low protection levels need to reserve a larger margin. Excessive humidity, in addition to affecting the insulation performance, will also cause the self-discharge rate of lithium batteries to increase, and the conductors are more susceptible to corrosion. As a result, the internal resistance of the system increases, and more electricity will be converted into ohmic heat and consumed during the charging and discharging process.

The IP level of walkie-talkie handheld terminal products reflects the waterproof and dustproof capabilities of walkie-talkies and accessories. Especially for outdoor work, it is inevitable to be in a harsh environment with high humidity or dust. The sealing and waterproof capabilities of walkie-talkies and accessories are crucial to ensure the safe operation and life of walkie-talkies. For this reason, the IEC529 standard was formulated internationally. In order to adapt to this, the Japanese industrial standard divides the waterproof protection of electronic products into 10 levels, represented by IPX1, IPX2...

The waterproof rating of Juda LARGE4073L and LARGE4074L lithium batteries is IP67, which can completely prevent dust from entering and can withstand immersion in water (1m) for more than 30 minutes in a short period of time. At the same time, Juda has improved and updated the battery cells and circuit boards of the battery, added power management functions, and made its use cycle times reach more than 1,000 times, ensuring user needs and battery life.

At present, the battery has been used in national defense science and technology, railway systems, small and medium-sized commercial users, and large projects such as national engineering, power stations, and walkie-talkies.

Introduction to IPX waterproof rating

IPX is an internationally used waterproof rating certification system. It is used to mark the waterproof level of the product on many instruments and equipment such as outdoor and diving, and is the most common technical indicator.

The IPX waterproof rating is divided into 8 levels, from IPX-1 to IPX-8, and the waterproof ability increases in sequence. IPX-0 means it is completely non-waterproof. The following is a list of IPX waterproof ratings for your reference.

IPX-0 No waterproof protection

IPX-1 The device can provide waterproof protection equivalent to 3-5 mm/minute rainfall for 10 minutes under normal operating conditions.

IPX-2 The level is basically the same as IPX-1, but it can pass the waterproof test of tilting 15 degrees in all directions.

IPX-3 60-degree splash waterproof protection, providing 2-5 minutes of 10 liters/second flow rate and 80-100n/m pressure waterproof protection.

IPX-4 The level is basically the same as IPX-3, but it can provide all-round and angle splash waterproof protection.

IPX-5 All-round and angle waterproof protection, providing 2-3 minutes of 12.5 liters/second flow rate and 30n/m pressure waterproof protection.

IPX-6 Big wave waterproof protection, can withstand 3 meters underwater depth, 100 liters/minute flow rate, 100n/m pressure for 2-3 minutes.

IPX-7 1 meter underwater can be immersed for 30 minutes.

IPX-8 is completely waterproof and can be used in water for a long time.
