Advantage
300W Polycrystalline Solar panel for home and off Grid Solar System
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 .

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 ESG SLA . 12v100ah solar lead acid llonglife deep cycle solar battery for ups and backup 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 ESG SLA 12v100ah solar lead acid llonglife deep cycle solar battery for ups and backup has a longer service life over 15years .
High discharge rate
Since the internal resistance is low .the 12v100ah solar lead acid llonglife deep cycle solar battery for ups and backup can provide high rate of discharge
Wide operation temperature range
ESG VRLA 12v100ah solar lead acid llonglife deep cycle solar battery for ups and backup 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 25”C .

Positive plates
|
PoPositive plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds lead dioxides as the active material.sitive plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds lead dioxides as the active material.

Negative plates
|
Negative plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds spongy lead as the active material.
|
Retain sufficient capacity.
Maintain capacity performance for long period of time (long life performance). Minimize self-discharge.
|
|
Separator
|
The advanced micro 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
|
The GEL Electrolyte is used as the medium for conducting ions in the electro-chemical reaction in the battery.

Container & Cover
|
Materials of the body and cover of the battery case are ABS resins, unless otherwise specified
|
Accommodates plate group consisting of positive and negative plates and separators.
Retains sufficient mechanical strength to withstand battery internal pressure.
|
|
Safety valve
|
Synthetic rubber with excellent acid resistance and little deterioration by aging. In cap shape. The valve is comprised of a one-way valve made of material such as neoprene.
|
Releases gas if cell internal pressure rises abnormally high and normalizes internal pressure. Prevents ingress of oxygen.

300W Polycrystalline Solar panel for home and off Grid Solar System
Solar batteries are an intricate component for off-grid electrical systems such as solar, wind, and mini hydroelectric systems.
All these systems produce DC electrical which must be stored so that it may be used at a later time. In order to do this at the present time we use deep cycle batteries.
Deep cycle batteries are used because they have the ability to be recycled many times. This means that they can go from being charged to being discharged to 50% numerous times without damaging the batteries unlike that of other batteries such as cranking batteries which are used to start vehicles.
The innovative Gel Technology does not only combines the advantages of lower internal resistance of deep cycle battery , but also do have much much better thermal stability and longer cyclic life .
