Product Details

Zhongneng Chengyu Power Co., Ltd is a professional manufacturer of various VRLA battery. Sealed Lead Acid (SLA) batteries come in a wide range of sizes, typically with voltages of 2V or 12V. Capacity is often used along with voltage to identify size of an SLA battery. SLA batteries are used extensively in applications such as children’s ride on toys, golf trolleys, emergency lighting or uninterruptible power supplies (UPS). They can be mounted on their side with no performance loss at all.

1. For safety precautions, the surfaces of battery cabinets and holders should be well insulated and acid resistant coated. Cabinets and holders of metal materials are strictly prohibited to directly load batteries without any insulation protection treatment

2. For safety precautions, the insulation layer can be placed at the bottom or the battery cabinets 3nd holders before the installation, so as to isolate the electrical connections between the battery body and the cabinets and holders The insulation layer can also prevent the following risks: sulfuric acid leakage

arisen from rupture of battery container, fire accidents resulted from the electric leakage circuit among the metal cabinets, holders and batteries due to acid liquid corrosion in cabinets and holders. The insulating layer materials selected should not cause corrosion to the battery container. Meanwhile, they

should have heat resistance, acid resistance, certain mechanical strength (not getting damaged owning to long-term battery pressure), and would take the forms of insulating strips or trays.

3. Make sure to tighten the battery connection according to the size of torques, and check frequently. Loose connection may cause fire accidents.
