Best OPzS Battery

Best OPzS Battery

OPzS2-1200-Y Product Features: Cycle life: >2200 at 80% DOD Self discharge rate ≤5%/month High charge acceptance performance; Wide operation temperature: -40℃~ 70℃ Good deep discharge recovery performance. Positive plate: tubular type, with die-casting thick Pb-Ca grid, it has very good...

Product Details

Best OPzS Battery are standby batteries with tubular plates,especially designed as battery backup power for all industrial applications which demand low-maintenance as well as average and long discharges. The tubular design with lead selenium alloy guarantees a longer operating life, minimum maintenance and optimal performances in cyclic and standby applications.

Product Features of Best OPzS Battery

Self discharge rate


Cycle life

>2200 at 80% DOD

Positive plate

tubular type, with die-casting thick Pb-Ca grid, it has very good

Battery Structure

1 Container and lid

Container and lid is PP material, based on the heat sealing technology to avoid leak of the electrolyte.

2 Negative plate

Thick with cage design for improved holding of the active material and high electrical conductivity.

3 Separator

Microporous polyethylene envelops, to ensure high performance and complete insulation between positive and negative plates,while allowing the free flow of electrolyte throughout the cell.

4 Positive plate

Matured tubular positive plate technology, use imported non-woven calandria in all plate calandria.

5 Terminal

Positive and negative terminal with large copper core cast lead alloy to ensure the battery large current discharge performance.

6 Safety valve

Unique mist collection reflux design, reduces water loss, and reduces maintenance frequency.

7 Flexible connector

With copper core to avoid loose caused by vibration and facilitate maintenance. Holes reserved on the protection cover of the connector for testing the battery voltage.
