Frequently Asked Questions

What is an OPzV battery and how does it differ from ordinary VRLA batteries?

An OPzV battery combines tubular positive plates with a gelled electrolyte in a sealed VRLA case. Compared with flat-plate AGM designs, the tubular plate holds the active material in porous tubes, while the gel immobilizes the acid, giving lower water loss and longer deep-cycle endurance.

What applications are OPzV batteries designed for?

They serve telecom base stations, solar and wind energy storage, UPS systems and other standby or cycling installations that need long service life, deep discharge tolerance and maintenance-free operation in a 2V cell format.

Why do tubular plates last longer than flat plates?

In a tubular plate the active paste is held inside porous gauntlets around lead spines, so it cannot shed during cycling and the grid is protected from corrosion. This keeps capacity stable over far more charge-discharge cycles than flat plates.

How do I choose between OPzV and OPzS batteries?

Both use long-life tubular plates. Choose OPzV when a sealed, maintenance-free gel battery is required, and OPzS when flooded cells with visible electrolyte and topping-up are acceptable and maximum cycle life at lowest cost matters most.

What cycle and float life do OPzV batteries offer?

With proper charging, tubular gel OPzV batteries are typically designed for around 15-20 years of float service and well over a thousand deep cycles at 80% depth of discharge, depending on temperature, charging accuracy and cycling depth.
