The discharge of chemical changed :
When connected to an external circuit the battery discharges, sulfuric acid that is with the yin, the anode active material board react to produce new compounds "lead sulfate." Released by the discharge of sulfuric acid from the electrolyte composition, discharge the longer, the more rarefied concentration of sulfuric acid. Consumed the composition proportional to the amount of discharge, as long as the measured concentration of sulfuric acid in the electrolyte, i.e., measured for specific gravity, or can be learned that the residual amount of discharge electricity.
2. Process of production
Absorbent glass mat (AGM). The glass–fiber separator in 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.
1.It’s designed to operate for up to 10 yearsat 20°C on the basis of accelerated tests
2.If depth of discharge is 30%, cycle service lifecan reach maximum at about 1000 times
3.Its warranty is 3 years for proper use .
4.Battery case is making of fire proofs material therefore the case is very strong. It can avoid the fire.
5.Its using insert terminal. And it is not only beautiful but also easily distinguished and installed.
6.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.
7.High power -to- weight ratio – SLA batteries can provide much power in comparison to its Weight
8.No Memory Effect. - Some batteries say nickel –cadmium batteries. It will become conditioned to provide less power after repetitious short usage /discharge.
9.Low self discharge–the self –discharge rate. Battery is about 2-3% per month at room temperature compared with 20-30% for other common battery systems.
10.Longer service life–utilized thick and massive calcium grate ensure that HENDA SLA battery has a longer service life
11.High discharge rate -since the internal resistance is low, the battery can provide high rate of discharge.
12.Wide operation temperature range– Our 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..
13.Easy of shipment - It is classified as non- dangerous goods and is acceptable to be shipped on passenger and cargo
