FT757 Battery Replacement

Replacing the battery in an FT757 in pictures

While hunting around the internet, I came across a document in French by Denis F4ANN about replacing the battery in an FT757 rig.

While maybe not homebrew strictly speaking, we are taking something apart, doing some soldering and putting it back together again (OK, technically it is 'repair work'). As I have an FT757 sitting on the shelf awaiting it's turn on the bench, I decided to translate it into English and put it into the 'information depository' for later. I also asked Denis's permission to put it on my website, which he agreed to. Rather than write it up as a web page, it is available to download as a pdf below. I figure others may want to store a copy locally rather than having to keep refering to a website they may forget where they saw it. One thing Denis did, was to replace the original battery:-

He also moved it to a more convenient location, should it ever need replacing again. This information may also be useful to anybody disassembling an FT757 for other repairs.
