12V 70ah Gel Deep Cycle Battery Used in Solar PV Systems

Product Description

•Solar, PV & Wind Power Systems
•Power Plants & Power Transmission Systems
•Signal System & Emergency Lighting Systems
•Golf Cars and Marine Boats
•Vacuum Cleaner, Lawn mower and other domestic applicances



Main Features:

♦Electrolyte Uniform Distribution 
NPS series battery is manufactured with high-quality gaseous silica to make the electrolyte in uniform distribution.
♦No Leakage
Curdled gaseous silica used in Gel batteries can immobilize the electrolyte and make the plates react evenly.
♦Longer Cycle Service Life
Deep Cycle design (high-density active material and thick plates) & special 4BS lead paste technology prolongs the cycle service life.
♦Excellent Deep Cycle Ability
Unique grid alloys & special positive/negative lead paste formulations makes the battery perform excellent in deep cycle using and recover quickly upon over discharging and extend the float service life.
♦Low Self Discharge
Using high purity raw materials and gel electrolyte ensures MCA batteries have less self-discharge. 
♦Environmental & Non-polluting
Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
♦Vibration Resistant
Using GEL fixed with acid give battery a high resistance to vibration. It also can be installed with an inclined angle up to 180^.

Battery Construction:
 

The Construction of a VRLA battery (all the batteries from our company belong to VRLA battery) is shown above. The following is the description of the different parts consisting of our batteries.

1. Plates (Electrodes)

Plate construction is the Key to produce a good battery. Recognizing this, Koyosonic utilizes the latest technology and equipment to cast grids from a lead-calcium alloy free of antimony. The small amount of calcium and tin in the grid alloy imparts strength to the plate and guarantees durability even in extensive cycle service. Lead oxide paste is added to the grid to form the electrically electrically active material. In the charged state, the negative plate paste is pure lead and that of the Positive lead oxide. Both of these are in a porous or spongy form to optimize surface area and thereby maximize capacity.

2. Separators

The separator is made of woven glass fiber cloth with high heat and oxidation resistance. The material further offers superior electrolyte absorption and retaining ability, as well as excellent ion conductivity.

3. Electrolyte

Immobilized dilute sulfuric acid: H₂SO⁴

4. Container

^{Case material is a ABS, a high-impact proof plastic resin, Styrene, or a polypropylene-polyethylene polymer with resistance to chemicals and flammability. For 2V, 4V, 6V, 8V and 12V batteries, standard container is manufactured from ABS plastic resin (UL94HB). It is optional to use Flame Retardant ABS plastic resin (UL94V0). Each cell has 2v in voltage and 4v battery has 2 cells. 6v battery has 3 cells, 8v battery has 4 cells and 12V battery has 6 cells.} 

5. Terminals
Depending on the battery model, the terminals may be Fastern type, bolt-and-nut type, pressure-contact type, cable-and-connector type or other special types. Some are threaded-insertion type or bolt-and-nut type.

6. Relief Valve
In case of excessive gas pressure build-up inside the battery (usually caused by abnormal charging) the relief valve will open and relieve the pressure. The one-way valve ont only ensures that no air gets into the battery where the oxygen would react with the plates causing internal discharge, but also represents an important safety device in the event of excessive overcharge. Vent release pressure is between 2-6 PSI and the seal ring material is neoprene rubber.

7. Case sealing
The case sealing is tongue and groove with polyrethane, epoxy, or heat seal. The ABS plastic cover and container are sealed by a special epoxy made in Japan and is acid resistant.
