In marine applications, battery reliability and longevity are key because replacement costs can be several times the initial cost of the battery. When you’re out of sight of the shoreline, you need a reliable power source to get you back to shore again. That’s why so many boaters, government agencies and conservation groups choose marine replacement batteries from TNR Technical. We use only the finest components from the best manufacturers to deliver exceptional quality in all maritime conditions.

In addition to batteries to power your watercraft, we carry replacement batteries for buoys, signaling, UPS, back-up systems and countless other pieces of maritime equipment. Ocean wildlife scientists rely on our custom battery packs to power their electronic tracking tags used on various sea creatures, including sharks, turtles and manatees. The National Oceanic and Atmospheric Administration (NOAA) trusts our batteries and custom battery packs to power their weather buoys. TNR can provide the long-lasting and robust batteries for your specific application.
