• Unsurpassed cycling service -
10 year average life
Benefit:
Use of thickest plate, highest density active material
in plate construction
Feature:
• Ability to remove sediment
chamber, eliminating separator
misalignment, treeing or shorting.
• Also allows for higher plates to
be used in the same sized cell,
which yields greater capacity.
• Less
maintenance
Benefit:
Enveloped Separators
Feature:
Increased Liquid
Reserve
Feature:
Many of our batteries are constructed with structural
foam containers
Feature:
• Less weight
• Greater rigidity
• Greater durability
