Hi dreamers and builders around the world!

I'm wondering if it is safe too use oil or WD40 too stop and prevent cells from corrosion?
First I was thinking too use epoxy but this will block the cell too puffs when it needs.

Someone a good idea
 
It will be fine, but unless you'll be soldering, it will not have proper soldering contact.
For normal spring contact I normally put a few drops of oil on paper and go over it... all my AAs are done this way. Also it prevent rusty of the spring.
 
Thanks men!

I going too use WD40 too preventing the cells before they get corrosion.
The cells are stored in my shed and isn't that well isolated;)
Yesterday I opened old bicycles batteries and there were some with light corrosion spots.

Better safe than fire!
 
Please keep in mind, that if your units are going to be outside or ventilated, WD-40 has a charge to it and will attract dust and create a nasty gunky residue on your cells. So you'd want to use an oil if possible.
 
The packs will be stored inside, but for now I'm disassembling the groups. I don't use laptops batteries but scooter beiges packs. This the reason some are little corrosion spots.

If everything goes as planned I spot welding the cells and not soldering it.

I don't understand why you would want to put WD40 on your packs. Everything is going to get covered in oil. Slippery slimy gross hard-to-wash-off-your-hands oil. If you're using the correct flux and solder they shouldn't be rusting...

Oil, which one? Not every oil is useable.
 
Mineral oil is the most inert oil to use. It's used in submersible pump motors.

However, if there's a little rust, just hit those spots with a lite tap of a dremel sanding drum and store them inside. That'll be the best option above all. Like Mike said, oil will make for a problem later on.
If you want to store them and keep rust from developing, it'd probably be better to store them with silica in the container. That'll absorb all the moisture from the air in the container.
 
I charge groups in the shed and after splitting them up I store them in inside.
 
If they corode inside then you have used wrong sodler or you did not clean away the flux after tinning the cells. No need to add any oil or such in side.
