12V 65AH
Deep Cycle Battery
Deep Cycle Series
Deep Cycle Battery is mainly made up of positive and negative
plates, special diaphragm, deep electrolyte, battery shell and
security valve and so on. Through colloid technology, the
electrolyte is fixed in solid state in battery. The advanced AGM
battery had greatly improved the cycling performance (cycling
increased 80%) by adopting the unique grid alloy and the
high-density lead paste formula The Deep Cycle series are
specially designed for applying in solar energy photovoltaic
power system

General Features:
1. Good Cycling Performance, 70% DOD (Depth of Discharge) ≥ 800 Times
The advanced AGM battery had greatly improved the cycling performance (cycling increased 80%) by
adopting the unique grid alloy and the high-density lead paste formula.
2. Excellent Charge Acceptance and Good Recovery after deep discharge or over discharge
Adopting unique grid alloy and special electrolyte formula, the deep cycle batteries are excellent in charge
acceptance and good in recovery after deep discharge or over discharge.
3. Superior Performance both in high temperature and cold environment
The advanced AGM battery has enhanced its working ability both in high temperature and cold environment by
adding a certain kind of special additive to the grid, the active substance and the electrolyte.
4. Sealed and Maintenance Free
Adopted valve-regulated sealed technology and has designed a special security valve in order to ensure the
safety and keep it environment friendly.
