agm deep cycle batteries

agm deep cycle batteries

DC12-26-Y Product Features: Long design life(25℃): 5 years(≤28Ah), 10 years(>28Ah) Low self-discharge rate: ≤3%/Month Good high rate discharge performance High sealed reaction efficiency ≥99% Wide operation temperature range: -20℃~60℃ Structure: Compact design, shorter internal connectors...

Product Details

Agm deep cycle batteries are designed to meet the requirements of frequent cyclic and high temperature applications. Such as broadband, PVs etc through up-to-date gel technologies. Our AGM batteries uses German origin high purity fumed silica to form sulfuric acid thixotropic Gel and fills to the batteries with vacuum to ensure the fully penetration of electrolyte through separators and plates pastes.

Product Features of agm deep cycle batteries

1. Optimized for a discharge of 15 minutes to 20 hours/ 100% cycle use;

2. Excellent cycle performance, is also suitable for higher ambient temperatures Withstand frequently deep discharge/ Internal gas recombination rate up to 99%;

3. The design life can reach ≥ 18 years on the condition that the floating charge and ambient temperature are controlled/ No danger to air / sea / rail / road transport/ Maintenance-free without adding water.

Long design life(25℃): 5 years(≤28Ah), 10 years(>28Ah)

Low self-discharge rate: ≤3%/Month

High sealed reaction efficiency ≥99%

Wide operation temperature range: -20℃~60℃


Compact design, shorter internal connectors between cells, thus low internal reisistance


Pasted flat type, with patent deep cycle formula of AM

Vent system

Gases can be vented through flame arrester / filter;


Using AGM separator, makes lower resistance higher assembling pressure to increase deep cycle life

Terminal sealing

Double sealing technics ( mechanical+epoxy gule).
