SLA Sealed Lead Acid Batteries

SLA Sealed Lead Acid Batteries

Zhongneng Chengyu Power Co., Ltd is a manufacturer of various VRLA battery. Sealed lead-acid (SLA) batteries come in a range of shapes, voltages, amperages and sizes. Rechargeable and maintenance free, SLAs power a vast array of devices and equipment. Our general purpose, high rate, deep cycle...

Product Details

SLA Sealed Lead Acid Batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types. One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.

Product Feature of SLA Sealed Lead Acid Batteries

Long-life design (25ºC): 10 or 18 years 

Low self-discharge rate: ≤3%/Month 

Good high rate discharge performance 

High sealed reaction efficiency: ≥99% 

Wide operation temperature range: -20ºC~60ºC

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



Emergency Light

Security System



Power storage plant

Q 1. what's the payment terms?

A. We accept T/T, L/C for big amount,PayPal, Western Union, Small-amount payment, Money Gram


Q 2. how's the delivery time ?

A. usually it will take about two weeks for production


Q 3. tell me the standard of package?

A. For the small capacity, it use carton, but for big capacity, we should use strong wooden case for protection.


Q 4. what kind of material of transformer?

A. For servo type stabilizer,we have two types, one 100% copper and the other is copper with aluminum.It depends on your requirement. In fact,those two have no difference if normal work well. Only except the long life. Copper is better and also higher price.For relay type stabilizer,we use toroid coils, the material is aluminum. comparing with square coils, toriod coils with high efficiency.


Q 5.Could you offer Form A or C/O ?

A. It totally not a problem. We can prepare relative documents to foreign affairs office or other office to apply for this certificate.
