CNB350 Battery Rebuild

CNB350 Standard Horizon Battery Pack Rebuild Service


This is a rebuild service for one Standard Horizon CNB350 battery. All of our rebuilds are professionally assembled using high-quality equipment and materials. All battery assemblies are load tested to insure quality. We have rebuilt hundreds of Standard Horizon CNB350 batteries that go into Standard Horizon HX350 / HX350S / HX255 Marine radios so please buy with confidence. The Standard Horizon CNB350 battery has been discontinued by the OEM. We can rebuild this battery many times to keep your legacy equipment powered when you need it. Do not invest tons of money into new equipment just because of a discontinued battery. Send those batteries to us and let us put our experience to work for you. 

Fits: Standard HX350 / HX350S / HX255 Marine Radio

Note: This is a rebuild service and not an attempt to sell a new or aftermarket battery pack. With this service, you must send your battery to us to be repaired.

Good job

I had a pleasureable experience with having my Standard Horizon CN350 battery pack serviced by MTO. The turn-around time was short and the quality of the battery that I received back has been wonderful thus far.

Amazing service

The CNB350 batteries that MTO Battery rebuilt for me are working like new again. I was very surprised when they came back to me because I could not even tell they opened them up. Great job!
