I. The Essence of Waterway Protection
"Waterway protection" is actually a waterproof design.The waterproof performance of the ternary lithium battery depends on the packaging process of the cell:
Square aluminum shell battery: Sealed by laser welding, it has strong resistance to water splashes.
Soft-pack batteries: They are encapsulated with multi-layer composite membranes, which prevent moisture but should not be immersed directly.
Cylindrical battery: Metal casing with pressure relief valve design, can prevent light rain but should avoid impact from high-pressure water jets.
II. Real Waterproofing Capability Test
In a laboratory setting, the performance of a typical lithium-ion battery is as follows:
Splash-proof: Capable of withstanding IP54 level protection (no impact from water splashing in any direction)
Short-term immersion: Some products can survive in 1-meter-deep water for 30 minutes.
Extreme environment: Exposure to -20℃ low temperature in combination with water may lead to the risk of shell cracking.
III. Daily Use Safety Tips
To make lithium batteries safer? Remember these three points:
Avoid using high-pressure water guns to rinse the battery pack.
Dry the contact surfaces promptly after use in a humid environment
Stop using it immediately if you notice any deformation of the casing.
Most battery modules will add waterproof gaskets and drainage holes, but each individual cell still requires careful protection.
