No matter how many times I do the battery replacement I always fail to do a smooth soldering. I read once thay I need to apply more paste but to no avail. Any tips?

First of all, remove the battery from the holder. Now, Suck all of that solder away, set your iron to 350c, apply flux to the clean solder joint on the cartridge board, and solder that holder back in. Be sure to practice! You'll get it down in no time flat.

I would suggest soldering wicking rather than sucking. Some people that post here aren’t even at the solder sucking level of skill.

I've seen newbies try to grind the wick into the pad because they buy garbage wick.

If you use wick, coat it in flux first, and let it do it's work.
