FEATURES:                                                                         

1) Maintenance-Free Operation

Absorbent Glass Mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected float service life of Double Tech batteries, no need to check the specific gravity of the electrolyte or add water. 

2) Good Discharging Ability 

Tight assembly technology ensures an excellent high-rate discharge performance. 

3) Long Service Life 

A unique corrosion-resistant grid alloy ensures Double Tech batteries have long service life.  

4) Low Self Discharge 

Using high purity raw materials ensures Double Tech batteries have less self-discharge. 

5) Environmental & Non-polluting 

Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.   

6) Safe & Reliable 

Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.  

The battery could be charged by solar and others, keep UBS connector, improving life convince.

 

APPLICATIONS AND MAINTENANCE:                                  

1) It’s Sealed Valve Regulated with none requirement to add extra water or

    maintenance when using  

2) Excellent High-Rate Discharge Performance: Being propitious to start with high

    current

3) Recharging: when open circuit voltage is lower than 12.6V(12V series) or 6.3V(6V 

    series) before using 

    Recharging Method: Charging 4-10 hours by 0.1C10 constant current 

4) Charging Voltage, when normal using, is 12.8V-14.5V(12V series) or 6.9-7.2V and 

    Max Charging Current 0.4-0.5C10(A) 

5) Application Temperature: -20-60°C  

6) Not upside down when transporting, storing and using  

7) Recharging: Offloading the battery to recharge when e-bike could not start well, 

    poor lamp lighting and weak trumpet 

8) Timely Recharging if long time no use. Normally, it’s 1-2months.

    Storage place should be prevented from humidity, high temperature and avoid to 

    keep in the place of corrosive gas and solvent.
