Deep cycle 12 volt batteries 12v 120ah sealed lead acid solar battery
Lead-acid battery consists of : positive plate, negative plate, electrolyte, AGM separator, battery slot, battery cover, pole, pouring cap and other components.
We carry out technical improvements lead-acid battery based on the introduction of created new maintenance-free batteries .
They can use for UPS float standby systems, also can meet the solar energy systems of daily charge and discharge all the time, and deep cycle work requirements .
Maintenance free
As it is value-regated .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 offer repetitious short usage /discharge
Low self discharge
The self –discharge rate for TOYO 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 TOYO 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
ESG VRLA battery capacity is rated at 20°C , and will operate from 15°C (5f)+50°(C (122F)when it is fly
charged Ambient temperature is 20°C.service life will be more efficient under 15’C to 25”C .

Parts | Material of construction | Function |
Positive plates | Positive plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds lead dioxides as the active material.Deep cycle Storage Batteries 12v38ah and 40ah | Retain sufficient capacity. Maintain capacity performance for long period of time (long life performance). Minimize self-discharge. |
Negative plates | Negative plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds spongy lead as the active material.Deep cycle Storage Batteries 12v38ah and 40ah | Retain sufficient capacity.
Maintain capacity performance for long period of time (long life performance). Minimize self-discharge.Deep cycle Storage Batteries 12v38ah and 40ah |
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.Deep cycle Storage Batteries 12v38ah and 40ah | Prevents short circuit between positive and negative plates.
Retains electrolyte.
Prevents active material fall by pressing plate surfaces.Deep cycle Storage Batteries 12v38ah and 40ah |
Electrolyte | The GEL Electrolyte is used as the medium for conducting ions in the Electronic-chemical reaction in the Deep cycle 12 volt batteries 12v 120ah sealed lead acid solar battery . | The GEL Electrolyte is used as the medium for conducting ions in the Electronic-chemical reaction in the Deep cycle 12 volt batteries 12v 120ah sealed lead acid solar battery . |
Container & Cover | Materials of the body and cover of the Deep cycle 12 volt batteries 12v 120ah sealed lead acid solar 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 Deep cycle 12 volt batteries 12v 120ah sealed lead acid solar 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. |

Construction
Deep cycle 12 volt batteries 12v 120ah sealed lead acid solar battery
1. Positive electrode plates
Positve plates are made of lead –calcium alloy with special chemical froma
2. Negative Electode plates
Negative plates are made of lead – ehemical froma
3. separator
The glass – fibre separator in HENDA SLA battery are made with advanced technology –this high porosity of
the separators retains adequate electrolyte for reaction with active matterial of the plates .
4.safe valve
The valve system which operaters from 1 psi to 6psi (0.07-0.43kg/cm3) is designed to relaease excess gas and keep
the internal pressure within the optmum range of safety .it protects the negative plates from contamination from oxygen
in the air valve are 100%visually inspected during battery production
If the internal pressure is increased to an abnormal level during overcharge ,the safety valve ill be opened to release gas .
it thus eliminates the danger of repture .once it has opened m it automatically closed in preparetion for future excessive increase in pressure.
5. Terminal
Depending on the battery model in MICRO series ,the terminals may b e fasten rype , bolt –and nut type , pressue
contact type ,cable –and connector type or other special types
Terminals of MEDIUM series and MACRO series are threaded –insertion type of bolt –and nuts types
Construction of threaded-insert strud
3.case
For 6v ,8v and 12v batteries ,standard container are manufactured from ABS plastic resin (94HB),It is optinal to use flame retardant ABS plastic resin (94vo)
Each 6v battery has 3cells .8v battery have 4cells and 12vbattery has 6cells
7Epoxy
The ABS platic cover and container are sealed by a special expoxy that is acid resistant .
