Chisen OPzV2-350- Comprehensive Analysis of the Tubular Gel Battery
Chisen OPzV2-350 is a 2V 350Ah tubular gel lead-acid battery (dimensions 124×206×471 mm, weight 26 kg) with a design float life of 20+ years, designed for backup power for medium applications. The OPzV2 series uses tubular positive plates with nano-gel electrolyte and is a sealed, maintenance-free lead-acid battery. (Source: Chisen OPzV/OPzS specification table)
The number "350" in OPzV2-350 denotes the rated capacity (C10 discharge rate) in ampere-hours (Ah). As a member of the Chisen tubular gel battery series, it retains the same tubular grid process and reliability standards while covering backup power for medium applications applications with 350Ah, balancing performance and cost.

The core of a tubular gel battery lies in two technologies: first, tubular positive plates (cast from Pb-Ca alloy) that wrap the active material in corrosion-resistant tubes, greatly suppressing softening and shedding of active material and thus delivering far longer cycle life and corrosion resistance than ordinary flat plates; second, nano-silica gel electrolyte that replaces conventional liquid electrolyte with a three-dimensional gel structure, completely eliminating electrolyte stratification and working stably across a wide -40℃ to +60℃ range. This design also makes the battery maintenance-free — no water refilling in normal use, and it can run unattended for long periods after installation.
Thanks to its 20+ year float life and excellent deep-discharge capability, the Chisen OPzV2-350 is mainly suitable for the following backup power for medium applications applications:
In these scenarios, when the mains power is interrupted or fluctuates, the OPzV2-350 quickly takes on the backup/energy storage role, keeping critical equipment powered.
The 350Ah capacity, combined with its backup power for medium applications positioning, strikes a good balance between backup duration and budget.
OPzV2 is a maintenance-free battery. Routine checks of appearance and terminal connections, keeping the surface clean with good ventilation, and setting charging parameters per the manufacturer's rated float voltage are sufficient. Its extremely low self-discharge and good deep-discharge recovery make it especially suitable for unattended sites and unstable mains conditions.
Reference charging parameters: float voltage 2.23V (25℃), temperature compensation -3mV/℃, equalize voltage 2.35V, cycle charging 2.40–2.45V, max charging current 0.20C10A. Use a charger that meets the specification and avoid overcharging or undercharging.
As demand for reliable backup power in telecom, power and data center infrastructure keeps growing, the value of long-life tubular batteries is increasingly evident. The OPzV2-350, as a 350Ah model in the Chisen series, is well suited as a standard option or upgrade for backup power for medium applications. When replacing existing batteries or planning new projects, please provide the system voltage and backup duration so the Chisen engineering team can prepare a configuration and total cost of ownership (TCO) proposal.
