Can I replace the lithium battery in my Ocean Guardian?

The lithium battery cannot be changed in any of the Ocean Guardian products. 

As all our products are designed for underwater operation at depth, they are sealed units. For example the FREEDOM7, SCUBA7 and SURF7 have been sealed with specific torque wrenches and o-ring seals, which if opened have to be replaced and the unit pressure tested. The FREEDOM+ Surf is an ultrasonic welded unit so cannot be opened. 

Out products come with a full 12 Month Warranty, and any failure outside warranty we have an affordable Factory Refurbishment program.
