Features of Eos Series1. Long life design, design life is over 15 years

2. 100%DOD cycle life is over 200 cycles

3. Reliable sealing performance, non-spillable, gas recombination efficiency is over 99.9%

4. Original capacity reaches 100%, residual capacity is over 94% after 3 months storage at 250C

5. Equipped with insulated and flame-retardant connector, and reserve mornitoring port

6. Easy for installation, horizontal installation is recommended.

7. Fully comply with IEC60896-2004

Long Life Design

* Advanced lead paste prescription

* 4BS lead paste technology

* Special lead-calcium grid alloy

* Thick plate design, low grid αvalue

* Prevent plate extention design

* Higher plate group compression ratio

* High sealing reaction efficiency, prevent water loss

Middle size lug design, reduce the density of current, then reduce the corrosion of grid

Reasonable structure, well-proportioned electricity line, prevent corrosion happen.

Long life design-Thick plate design

Long life design-4BS lead paste technology

• High temperature high humidity drying and curing process,forms thicker grid corrosion coat.

• Solid framework, better mechanical strength.

• Long cycle life

Special additives have been added to lead pa

ste, the best prescription has been chosen by

comparsion of comprehensive peformance on

capacity, life, large current discharge perform

ance.

Special lead-calcium grid alloy

Saddle has been installed in the bottom of container,

which is using for prevent plate extention

Long life design-Prevent plate expansion design

Oriented bar design Oriented bar design has been adopted to internal of battery container, it helpsthe plate group enter into the batterycontainer easily, meanwhile the space between plate group and container can be larger, this will improve the gas recombination efficiency.
