LIBERTY® Series 2000 VRLA Battery

Dependability...Inside and Out.

We have taken the top-rated, most dependable VRLA battery available and added the latest technology to create the Liberty 2000 MAX ™. You get maximum back-up performance and reliability whether you are supporting a cell site, central office, uninterruptible power system, switchgear or Internet server applications.

The Liberty 2000 MAX is the result of years of research in refining the best VRLA battery system on the market. Our numerous patents provide longer life and reduced maintenance. This translates to a lower life cycle cost, while ensuring maximum back-up power when you need it.

The Maximizer™ Makes the Best VRLA Battery Even Better

The Maximizer is the patented cap system that reduces corrosion of the positive grids, maintains a properly charged negative plate, and virtually eliminates dry-out. The Maximixer also:
  • Reduces float current
  • Maintains cell capacity
  • Creates lower impedance
  • Saves you money (with its lower current and longer useful life)

Excess oxygen is attracted to the Maximizer and prevented from affecting the negative plate potential.

*Add 4.9 inches (125 mm) for HD/HDL, or 4.4 inches (112 mm) for RHD/RHDL, to the height of the base support, for total stack height.
The base support weight ranges from 34 lbs (15.3 kgs) to 55 lbs (25 kgs) depending on width. A reduced height (2.5 inches tall) base is available as an option.
**Total depth includes clear faceplates over terminal connections. Subtract 1/2 inch (12.7 mm) without faceplates.
†These modules can be installed in a 23-inch relay rack. Allow 4 inches (102 mm), the height of the rack base, for the total stack height.
††Stack height is limited to six modules for seismic zone 4.


Design a system using these standards building blocks. You can:

  • Mount modules in relay racks
  • Mount relay rack on top of modules
  • Build complete front access system
  • Vary module widths to spread floor load
