The first generation Pokemon games all used significantly less power to maintain their RAM battery saves than Pokemon Gold, Silver, and Crystal by virtue of not having a real time clock constantly ticking the power away. RBY saves only needed to maintain the power for the save itself and did no additional work on top of that.
Original GSC cartridges would last about 10-15 years, whereas RBY could last 20-30 years. We’re currently in the span of time where many RBY cartridge batteries will be failing but it’s still possible to find ones with functional original saves on batteries just barely holding on.
Many people like to try using physically larger batteries when doing replacements, but most of them don’t realize the batteries aren’t losing charge at the end of those many years because they’re drained and out of power. RBY saves use so little power from the battery in the cartridge that they won’t fully drain it after 30 ish years. Instead the battery saves fail because the batteries themselves fail after 20-30 years. Picking the larger button cell batteries won’t help since they’ll still have the same total lifespan and will still lose charge at almost the same rate as the spare batteries that weren’t installed in your cartridge of choice.
On top of this, don’t assume someone’s tech literate just because they’re in a certain field. It took me seeing first hand at a previous job how the IT techs did their job to realize why we ran into so many issues.
We were having some software installed on every computer which apparently had to be installed via PowerShell. While watching our usual IT tech go through the steps on the machine next to me, I offered to help him get this job done faster by starting it up on my machine then he could run his credentials whenever the prompts came up. He knew I was computer literate since we had talked about tech stuff and about how I was at the time trying to get a job in IT, so he gave me a copy of the .txt file with all the instructions and commands to run.
In the file was an 11 step process written by the director of the IT department explaining how to open PowerShell, copy the command below, and run the command. 3 of the instructions were to highlight the command (between the quotation marks without including the quotation marks), right click the highlighted portion, then click on “Copy”.
The tech didn’t believe that I had actually copied the command when I just did Ctrl+C, so he specifically stopped me to tell me to right click the command. I told him that it was copied already with Ctrl+C, and he told me, “No, it won’t work if you don’t do the right click.”
I also found out later that said IT director didn’t seem to be aware that there were multiple types of USB cables. He was setting something up in my boss’s office and sent someone to ask for “a USB cable.” Said person knew I had a bunch of cables at my desk as part of my work at the time so they relayed the request for “a USB cable.” I asked them, “What kind? USB C to C? A to C? Micro? Mini?” “Idk, they just said ‘a USB cable.’”
I think, “fair enough, my coworker isn’t very tech literate so I’ll just ask the man myself.” I bring over an assortment of cables and walk to the office with my coworker. Director see my coworker with me now next to them and ask me for “a USB cable.” “What kind?” “Just a regular USB cable, if you have one.” I show him my bundle of about 6-10 assorted cables, explain that I have a variety, see that he’s working on a small printer/scanner, and offer him one. “Would a type 3.0 USB A to B cable work?” “What? No, I just need a regular USB cable.” I show him the A to B cable and he responds “oh yeah, that’s what I was saying. A regular USB cable.”
