Those batteries don't leek as far as I know as they are solid, but they can generate corrosion if the board gets dirty and/or wet. The blue caps can leak, but you probably don't want to take those out for storage, you could protect the PCB with some conformal coating in case they leak but all that seems over kill. Not likely to get serious damage for stored PCBs without a battery, caps aren't very likely to leak when unpowered and if there is no power around corrosion isn't as bad as if there is some DC power around. Hence, taking out the battery and checking once every a few years should do. If you want to save the game achievements as if you have a very very high tetris score is the only reason to leave the battery in I guess. JS |

Humidity control... you don't want things to dry. 40%-60% is the range most assembly pants run at to keep esd from being a problem. |

The only problem is that if I want to remove the battery I should desolder is and I don't want to damage or touch the original cart. Do you think that letting the battery on the board is too risky? If the battery will die it is not be a problem but corrosion of the PCB IS a problem. What's the best thing I can do if I want to keep the battery on? |

I heard that humidity would damage the PCB and a dry environment too. I would like to make my best to protect a pair of cartridges that are really rare without desoldering or modify them. It doesn't matter If there's an expensive solution, I'm looking for the best one I can |

As long as your electronics are inside an ESD bag, they will not be affected by electrostatic charges, so there is no requirement to raise the humidity in storage. To prevent possible corrosion from condensation, you can use silica gel packets which absorb moisture. If you are keeping the plastic clamshell around the PCB, there is zero possibility of anything shorting to the ESD bag and removing the coin cell is not required. CR or BR type cells do not leak and they do not contain corrosive electrolyte. |
