Terminal contacts grease substitutes for batteries?

(1/5) > >>

Boris_yo:
Hello. I don't have terminal contacts grease but I do have WD-40 specialist silicone spray and silicone grease.

Would both work for protecting AA/AAA alkaline and NiMH batteries - (minus) surfaces from oxidation and corrosion? I have already applied contact cleaner.

Thanks

AVGresponding:
If you get an insulator like silicone between the cell terminals and the spring terminals, there's a good chance the device will stop working. Woe betide you if you get in inside a power switch...

Gyro:
Vaseline, the universal contact lubricant and corrosion protector.

wraper:
Unlikely to protect from anything. NiMH will not leak. When alkaline leaks, not likely it will save anything.

As AVGresponding said, don’t use silicone. While I think it’s unlikely to prevent electrical contact, if the silicone is heated (like in an arcing event, including e.g. when you see a spark) it can decompose into silicon dioxide (sand), which is an abrasive. Hence the NEVER getting silicone into switches warning!!
