2. Advantages
Free Sample Free Sample Green Energy AGM Sealed Lead Acid Batteries12V7ah 8ah 9ah 12ah UPS Back Storage battery
| Maintenance free | As it is value-regated .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 offer repetitious short usage /discharge |
| Longer service life | The self –discharge rate for TOYO SLA . battery is about 2-3% per month at room .temperature compared with 20-30% for other common battery systems . |
| Low self discharge | Utilized thick and massive calcium grate ensure that TOYO SLA battery has a longer service life over 15years . |

4.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
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

Constant voltage charing |
Regulation rang of constrolled voltage (20c.68F) 6V BATTERY :6.75Vto6.9v 8v battery:9.00v to 9.2v 12v battries 13.5v to 13.8v |
Regulation range of controlled voltage (20C ,68F0 6V BATTERY :7.2Vto 7.5v 8v battery:9.50v to 10v 12v battries 14.4v to 15.0v |

This method can provide a short –time charge |
The charg’s current capacity must be big enough to maintain the specified charging voltage during float |
Short –tim charge allowed |
||
|
Same model battery under the same storage can be charge in series other wise ,they should be rechared in separate groups |
||||
|
The charge voltage must be stabilized otherwise , battery may be overcharged or dicharged The chargeer should be trmperature compensated when using battery in a wide range of ambient temperature |
