ESG 12V 18AH 20hr SLA AGM UPS Valve regulated lead acid rechargeable battery

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.

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.

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 ESG 12v 18ah 20hr SLA AGM UPS Valve regulated lead acid rechargeable battery.

Container & Cover

Materials of the body and cover of the ESG 12v 18ah 20hr SLA AGM UPS Valve regulated lead acid rechargeable 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 ESG 12v 18ah 20hr SLA AGM UPS Valve regulated lead acid rechargeable 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.
