Failing Battery Terminal Ends: Symptoms and Solutions
If the battery terminals have corrosion, you can clean them by applying a solution of baking soda and water to each post. Rinse with water, then wipe dry with a rag. Next, smear petroleum jelly on each terminal to protect the battery from corrosion. To connect the terminal ends, seat the positive terminal followed by the negative terminal.
Is the Yaesu FT-5d cracking issue as bad as it seems? : …
I have an FT5D and yes, it is cracked. The radio is maniacally kept (screen protector, leather case, etc) even though the crack started developing and broadening. It does not impair the radio usage but, as long as it grows, the radio looses its IPxx rating and may also start developing tolerances with the battery.

The local lithium plating caused by anode crack defect in Li-ion battery
The main effect of anode crack defects is the triggering of local lithium plating. Lithium plating occurs when the anode surface is saturated or the interfacial overpotential is below 0 V vs. Li/Li + [16].To avoid it, the anode capacity is designed to be larger than the cathode capacity [17], and the charge current and operating temperature are limited [18].
