Lithium battery waterproof level, IP67 dustproof and waterproof lithium battery pack -Lithium - Ion Battery Equipment
If the protection level of the lithium battery shell does not meet the dustproof and waterproof requirements, the environmental conditions of the battery cells and electrical components will be uncontrollable. In a general working environment, excessive dust will reduce the insulation performance of electrical devices. Relatedly, for electrical clearances and creepage distances, in systems with low protection levels, a larger margin needs to be reserved. In addition to affecting the insulation performance, excessive humidity will also cause the self-discharge rate of lithium batteries to increase, making the conductors more susceptible to corrosion. Then 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 rating of the walkie-talkie handheld terminal product reflects the waterproof and dustproof capabilities of the walkie-talkie and its accessories. Especially for outdoor work, where it is inevitable to be in a harsh environment with high humidity or dust and sand, the sealing and waterproof capabilities of the walkie-talkie and accessories are essential to ensure The safe operation and life of the walkie-talkie are crucial. For this reason, the IEC529 standard has been formulated internationally. In order to adapt to this, the Japanese Industrial Standards divide the waterproof protection of electronic products into 10 levels, represented by IPX1, IPX2... respectively.(Lithium - Ion Battery Equipment)
The waterproof rating of LARGE4073L and LARGE4074L lithium batteries is IP67, which can completely prevent dust from entering and can withstand water immersion (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, and added power management functions, so that the number of cycles can reach more than 1,000 times, ensuring user needs and battery life.
At present, the battery has been used in national defense science and industry, railway systems, small and medium-sized commercial users, as well as large-scale projects such as national projects, power stations, and walkie-talkies.
Introduction to IPX waterproof level
IPX is an internationally accepted waterproofing level certification system. It is used to mark the waterproof level of the product on many outdoor, diving, and other instruments and equipment, and is the most common technical indicator.
IPX waterproof levels are divided into 8 levels, from IPX-1 to IPX-8, with waterproof capabilities increasing in sequence. IPX-0 means completely non-waterproof. The following is a list of IPX waterproof levels for your reference.
IPX-0 no waterproof protection
IPX-1 equipment can provide waterproof protection equivalent to 3-5 mm/min rainfall for 10 minutes under normal operating conditions.
The IPX-2 level is basically the same as IPX-1, but it can pass the waterproof test when tilted up to 15 degrees in all directions.
IPX-3 60-degree splash waterproof protection provides 2-5 minutes of 10 liter/second flow rate and 80-100n/m pressure waterproof protection.
IPX-4 level is basically the same as IPX-3, but 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 large wave waterproof protection, can withstand a depth of 3 meters underwater, a flow rate of 100 liters/minute, and a pressure of 100n/m for 2-3 minutes.
IPX-7 can be submerged under 1 meter of water for 30 minutes.
IPX-8 is completely waterproof and can be used continuously in water for a long time.
