2V 350AH420AH490AH Longest Lasting UPS Sealed lead acid solar dry cell tubular OPzV battery
APPLICATION
2V 350AH420AH490AH Longest Lasting UPS Sealed lead acid solar dry cell tubular OPzV battery
1.BATTERY PROPERTIES
Maintenance free
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 .
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 HENDA 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 HENDA 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
HENDA sla 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 gel deep cycle battery for solar street light

|
Separator |
The advanced medium 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 |
Acid Electrolyte |
The Electrolyte is used as the medium for conducting ions in the electro-chemical reaction in the battery. |
|
Container & Cover |
Usually, it should be ABS resins. But can do as client’s request. |
Accommodates plate group consisting of positive and negative plates and separators. Retains sufficient mechanical strength to withstand battery internal pressure. |
|
Safety valve |
In cap shape. The valve is comprised of the one-way valve, which is made of material such as neoprene. |
Releases gas if cell internal pressure rises abnormally high and normalizes internal pressure. Prevents ingress of oxygen. |
