[2020] How to Solder 18650, AA, 9v, or ANY Other Battery (To Make Battery Packs) | Safe & Quick

This very quick and informative guide will show you how to solder any battery (Including Li-poly & lead acid). This guide will be useful if you are planning on making a battery pack or similar device and have a tight budget on tools. You can get a good soldering iron for as low as $10. 3 example batteries were shown in the video so that the viewer can have an understanding of the soldering process on a variety of different batteries. The same process is followed despite the type of battery. Please understand though, a general knowledge of batteries (and their safety) is required before attempting anything in this guide. Other than that you should have no problems. By following the steps shown in this guide, you comply to the disclaimer shown below in this video's description. Subscribe to join DaGoose Flock! ;)

I just applied your method. My soldering kept falling off. I scraped surface and used soldering paste and it helped. Thanks buddy

[dalegass]

I've been mucking with electronics for decades, soldering for all of that. But I picked up some handy tips from this video. Really well done!

[zerodefault]

Just repaired my portable blender, thanks man

As a general rule, fine sandpaper was missed. You can’t see microscopic oxidation which prevents bonding.

I tried soldiering my 18650 battery for a few hours, but the soldier would never stick to the battery. It felt like the flux even made it worst. So I just held the strip with electrical tape.

[jameslfowler]

kind of always thought that soldering a battery would make it rupture and explode? the things you learn sitting on ass at can be educational. cheers dude!

[GarethCometa]

Is a battery with little remnants left on still safe to use?

[PaulChaplo]

What kind of flux is best for this? It is acidic?

[Koryteq]

Hi, thanks for the video. Does it matter where exactly I put the wire in a 9V battery? I see that in your 9V battery in '+'
you soldered a wire exactly in the middle, but in '-' at the edge of the spot. Thanks

[tausiprahmanshihab]

Thanks you so much sir
From Bangladesh 🇧🇩🇧🇩

[AndroidK]

I don't know when I'll use this, but thank you

[ryszardsinius]

If you have a 9V battery, just take a screwdriver, snap the pin heads off the battery and solder with the surface beneath it

[iGentle]

My solder doesn't stick to the metal of the battery nor the nickel strip. Are you using anything special?

[SacredHeart]

Do not use a screwdriver to prep the battery use empty cloth or sand paper

[saurabhjuvekar]

No matter how much I try to solder strip and battery, I failed everytime. It's very hard to apply solder to nickel strip even with flux. I try so much and end up buying new trimmer... 😄

How about Gameboy cartridge battery like the 1616 for Pokemon

[geminigem]

IS it dangerous to solder batteries. ? What to look out Safety factor when solder?

[gtasandman]

Will this work with button cells? like a 2016 size.

[viktorbachew]

bro what is that liquid or smtg over the batery 0:38

[ninomandal]

We can simply connect a 9v battery connector for the 9volt battery... So no need to solder.
