Batteries

All Nortek instruments deployed in autonomous configurations require batteries to operate. Since not all requirements for deployment length and sampling scheme are the same, we offer a variety of battery sizes and chemistries so that you have a real choice in how you operate your instuments.

All of the batteries described below have been developed especially for Nortek and they have been tested in a variety of deployment configuration to ensure proper performance across the full temperature range found in the ocean.  They are produced by specialist manufacturers and are protected with diodes. Because of the importance of the battery pack for successful deployment and the warranty implications of a failed battery, we do not recommend that you build your own battery packs

Battery packs can be mounted inside the instrument or they can be external. Both our AWAC and Continental instruments have no space inside the instrument and both use one or more external battery canisters
