Vrla Deep Cycle Battery2v500ah Solar Battery .

Specifications

 1. Absorbent glass mat (AGM). The glass –fiber separator in HENDA SLA battery are made with advanced technology – this high porosity of the separators retains adequate electrolyte for the reaction with active material of the plates. 

2. It’s designed to operate for up to 10 years at 20°C on the basis of accelerated tests

3. If depth of discharge is 50%, cycle service life can reach maximum at about 1600 times.  

4. Its warranty is 5 -7years for proper use in telecommunication.

5. Battery case is making of fire proofs material therefore the case is very strong. It can avoid the fire.  

6. Its using insert terminal.  And it is not only beautiful but also easily distinguished and installed.  

7. Maintenance free As it is valve-regulated sealed. Glass -mat is utilized acid is trapped inside .It is leak proof and refilling is no needed.  

8. High power -to-weight ratio –HENDA SLA batteries can provide much power in comparison to its Weight

9. No Memory Effect. - Some batteries say nickel –cadmium batteries. It will become conditioned to provide less power after repetitious short usage /discharge.

10. 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.

11. Longer service life –utilized thick and massive calcium grate ensure that HENDA SLA battery has a longer service life

12. High discharge rate - since the internal resistance is low, the battery can provide high rate of discharge

13.Wide operation temperature range – HENDA SLA battery capacity is rated at 20 °C, and will operate from -20°Cto + 60°C  when it is fully charged. Ambient temperature is 20°C, service life will be more efficient under 15°C to 25°C..

14. Easy of shipment- It is classified as non- dangerous goods and is acceptable to be shipped on passenger and cargo aircraft.
