 agm as baterias de gel solar smf battery Reliability 12 volt battery 12V7AH Battery for UPS systems

1.BATTERY PROPERTIES 

Maintenance free

 smf  battery

As it is value-regulated .sealed and glass mat is utilized .acid is trapped inside . so refilling is not needed and is leak proof.

NO Memory Effect

 

Some batteries say nickel –cadmium batteries.will become conditioned to provide less power after repetitious short usage /discharge .

No memory effect 

 

Some batteries .say nickel –cadmium batteries will become conditioned to provide less power offer repetitious short usage /discharge

Low self discharge

 

The self –discharge rate for HENDA SLA . battery is about 2-3% per month at room .temperature compared with 20-30% for other common battery systems .

Longer service life

 

Utilized thick and massive calcium grate ensure that HENDA SLA battery has a longer service life over 15years .

High discharge rate .

 

Since the internal resistance is low .the battery can provide high rate of discharge

Wide operation temperature range

 

HENDA sla battery capacity is rated at 20°C , and will operate from 15°C (5f)+50°(C (122F)when it is fully charged Ambient temperature is 20°C.service life will be more efficient under 15’C to gel deep cycle battery for solar street light

Parts  

Material

Function

Positive plates

Lead - calcium alloy with special chemical formula.

Retain sufficient capacity. Maintain capacity performance for long period of time (long life performance). Minimize self-discharge.

Negative plates 

Lead - calcium alloy with special chemical formula.

Retain sufficient capacity. 

Maintain capacity performance for long period of time (long life performance). Minimize self-discharge.

Separator 

The advanced medium porous Absorbed Glass Mat (AGM) or PVC separators retain electrolyte and prevent shorting between positive and negative plates. Separators adopt a non-woven fabric of fine glass fibers, which is chemically stable in the diluted sulfuric acid electrolyte. Being highly porous, separators retain electrolyte for the reaction of active materials in the plates.

Prevents short circuit between positive and negative plates.

Retains electrolyte.

Prevents active material fall by pressing plate surfaces.

Electrolyte

Acid Electrolyte

The Electrolyte is used as the medium for conducting ions in the electro-chemical reaction in the battery. 

Container & Cover

Usually, it should be ABS resins. But can do as client’s request.

Accommodates plate group consisting of positive and negative plates and separators. 

Retains sufficient mechanical strength to withstand battery internal pressure.

Safety valve 

In cap shape. The valve is comprised of the one-way valve, which is made of material such as neoprene.

Releases gas if cell internal pressure rises abnormally high and normalizes internal pressure. Prevents ingress of oxygen.

• The battery electrolyte contains fumed silica, and there is no flow, no leakage or no gradation of acid liquor.  The battery slot and cover is made of ABS materials through hot seal.  There is no risk of leakage during the utilization and transportation, and it is safe and reliable.

• The gel electrolyte is in dilute sol state when being injected.  Excessive electrolyte can fill in all the space inside battery.  Under circumstance of high-temperature and overcharge, the battery will not dry out.  The gel battery has large heat capacity and good radiation performance.  It is not easy to appear thermal runaway.  The battery can work under severe environment.

• The grid of electrode plate is in radial structure, which is favorable for improving the utilization rate of active materials.  Pb-Ca-Sn-Al alloy makes the positive plate have a good performance of corrosion proof and makes the negative plate have a high over-voltage of hydrogen evolution.  Unique lead paste formula enables perfect recovery performance of battery recharging after deep discharging.  The battery has strong cycle and duration performance, sufficient capacity and long life.

• The terminal is in the structure of tin electrodeposited copper terminal, which is favorable for discharging battery with large current and is favorable for the reliability of connection between batteries.  The terminal is sealed through fusion welding and second seal of resin sealant, and the seal reliability is high.

Danger

• Do not use at the places near fire. Hydrogen gas generated from battery may cause fire and explosion.

• This 12v battery is only for starting engine. Do not apply for other uses.

• Keep out of the reach of children or the personnel who do not understand the manual. It may cause blindness or severe burn.

• When using the battery, wear safety glasses and rubber gloves. Sulfuric acid may cause blindness or severe burn.

 

Warning

• Replacement of battery shall be performed as per following order. If failed, it may cause fire and explosion. Remove cable from negative terminal first. Connect cable to negative terminal last.

• When connect cable to battery, make sure not to get changed post of +and -. It may cause the damage of electronic components or fire.

• When using the battery, handle with care, sulfuric acid may cause blindness or severe burn.

 

Caution 

• When moving battery, be careful not to drop the battery, which is heavy, do not shake the battery with handle, if there is the handle, It may cause the injury.

• Do not shore the battery at the following places. High temperature & humidity, or being exposed to rain, snow, and sunshine directly
