SeaBattery™ Power Module

Batteries Large

  • 6 V, 12 V, 24 V, and 48 V configurations
  • Pressure compensated design
  • 11,000 m depth rated
  • ABS Certification available
  • High current option

The subsea community has relied on our SeaBattery Power Module for over 30 years. The durable design works in the most demanding subsea applications. This battery has a pressure compensated design and an 11,000 m depth rating. 6V, 12V, 24V, and 48V configurations are available. ABS Type Approval is available.
SeaBattery Power Modules use Absorbent Glass Mat (AGM) lead-acid cells which add vibration and shock resistance. These Power Modules continue to work when inverted. The SeaBattery Power Modules do not have the same shipping restrictions as lithium ion batteries.

A high current SeaBattery is offered for applications that require current draws of up to 100 amperes.

The SeaBattery enclosure is available for use as a junction box.
