CSBattery DC2 series batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycle (deep cycle). The CSBattery deep cycle AGM battery uses a different chemistry for the plates active paste material, and a slightly stronger electrolyte than normal battery electrolyte, thus the DC2 range features 30% higher cyclic life with 10 years of float life when compared to the standard Duration range.

We are specialized in Solar/UPS/Car/Telecom battery industry since 2003.
12V upto 300Ah , 2V upto 3000Ah.
