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.
Product Feature of Sealed Lead Acid (SLA) Batteries
Long-life design (25℃): 10 or 18 years
Low self-discharge rate: ≤3%/Month
Good high rate discharge performance
High sealed reaction efficiency: ≥99%
Wide operation temperature range: -20℃～60℃
Grid: thicker grid and radiative grid structure
Structure: Compact design, lower internal resistance/high specific energy
Plate: Pasted flat type, with patent formula of AM/ latest grid alloy + patent formula of AM
Terminal: two or more types terminals are convenient for selection
Separator: using improved AGM separator, makes lower resistance, higher assembling pressure to increase cycle life

A.B.S. UL94-HB, UL94-V0 Optional
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.

Q1: What're the terms of payment?
A: T/T 30% deposit in advance, The Balance before shipment.We'll show you the photos of the products and packages before you pay the balance.
Q2: What're kinds of battery we supply?
A: AGM, Gel, OPzV/OPzS Batteries usage in the Solar system, UPS, Street Light, Control Equipment, Wind energy system, Telecommunication, Emergency System etc.
Q3: How to maintain the battery?
A: The battery should be stored in clean, dry, ventilated, dark environment when not using, keep it after a full charge, recharge it every 3 months or 6 months.and must use it in One year.
Q4: If we could accept OEM & ODM Service
A: We could accept customized, such as the brand, Logo, Container color etc. The premise is to reach a certain Quantity.
Q5: MOQ & Samples
A: According to the certain voltage and capacity of the batteries you need, different battery with different MOQ.Because of the shipment. we really want to offer you a sample, but our batteries cannot be shipped by express or air.so the MOQ must more than 300kg of total batteries.
Q6: About the certificates & Other services
A: We have a professional export sales team with full experience, and you just need to confirm the batteries you need and also advise us the certificates you need and the docs for customs clearance.
