Thread: DIY replacement battery for ResQLink PLB

Presolder the tabs and preflux the battery end, jig to steady and hold tab against battery end, touch briefly with hot solder iron.

It can be done with a pretty low amount of heat going into the battery, depending on flux core increases the heat needed. Practice by making a duracell battery pack.

Use leaded solder, sticks better to stainless / chrome surfaces than the lead-free solder does.
