12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage Advantage

Maintenance free 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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

Longer service life 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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

High discharge rate 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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

Wide operation temperature range 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

ESG VRLA 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 25”C . 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

Negative plates 

Negative plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds spongy lead as the active material. 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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.  12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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.   12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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   12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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. 12v250ah Sealed Gel Deep Cycle Batteries for solar Energy Storage

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

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 .
