International Logistic Service Maintenance free Toys & Consumer Electronics 4V 4ah 4V 4.5AH rechargeable lead acid battery
Application
Maintenance free Toys & Consumer Electronics 4V 4ah 4V 4.5AH rechargeable lead acid battery 
Construction
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

|
Positive plates |
Positive plates are plate electrodes of which a grid frame of lead-tin-calcium alloy holds lead dioxides as the active material.Maintenance free Toys & Consumer Electronics 4V 4ah 4V 4.5AH rechargeable lead acid battery |
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.Maintenance free Toys & Consumer Electronics 4V 4ah 4V 4.5AH rechargeable lead acid battery |
Retain sufficient capacity. |
|
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.Maintenance free Toys & Consumer Electronics 4V 4ah 4V 4.5AH rechargeable lead acid battery |
Prevents short circuit between positive and negative plates. |
|
Electrolyte |
The GEL Electrolyte is used as the medium for conducting ions in the Electronic-chemical reaction in the Maintenance free Toys & Consumer Electronics 4V 4ah 4V 4.5AH rechargeable lead acid battery . |

Container & Cover |
Materials of the body and cover of the Maintenance free Toys & Consumer Electronics 4V 4ah 4V 4.5AH rechargeable lead acid battery case are ABS resins, unless otherwise specified |
Accommodates plate group consisting of positive and negative plates and separators. |
|
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. |
