They can be used directly and normally. This battery is a lithium battery with a casing. Why should a casing be added to the battery pack? There are many reasons. For example, for the convenience of carrying, for the convenience of storage, for the sake of beauty, to prevent other external factors from damaging the battery pack, etc., the core reason is to protect the battery. The advantages of the battery case are as follows: Mechanical properties: Mechanical properties also include impact resistance, vibration resistance, extrusion and bump resistance. It should also include consideration of natural disasters (such as earthquakes) and swelling caused by surplus gas in the battery. Corrosion resistance: If the battery tank is in contact with a sulfuric acid solution with a density of 125~132g/cm3 for a long time at a certain temperature, there should be no changes due to long-term corrosion, such as swelling, cracks, and discoloration. Oxidation resistance: The battery may work in various environments, so it is required that the battery tank should not be discolored and brittle under the chemical action of ultraviolet radiation or atmospheric erosion, otherwise the appearance and mechanical strength of the battery will be affected. At the same time, the battery tank should also have the ability to resist oxygen penetration.
