Can anyone tell me what type of rechargeable battery the original EFA-Linker uses? I bought a vl-2020, but I need to make sure it's right before putting it in.

I don't know if things changed during later batches or anything.
Hopefully you got one with tabs already welded on in a suitable location.

However you can usually figure out if something will be compatible.

The numbers refer more to the size of the cell itself ( https://www.batteriesandbutter.com/coin_batttery_chart.html ) and thus you can measure the size of the existing one/slot it went into/size on a picture if you have to and get an idea.
Larger battery = more stuff you can fit in it and thus more chemical to store energy and in the extremes more power it could deliver at full load which your little "keep the data in the save chip" battery is likely never to even come within sniffing distance of. Some even see if they can get away with a larger one still.

There can be a variation in voltage (some of the smallest things might be 1.5V where bigger stuff might be 3V). In this case if you find the save chip's datasheet you could then figure out if the keep alive voltage is high enough from a battery in normal use (if the 1.5 drops to 1.2 in short order/during normal discharge then yeah, and I very much doubt a GBA era flash cart used any of the fun DC-DC conversion we have today when they could have just used a battery).

    The younger generation uses mostly TikTok and YouTube, some Instagram. It seems like they don't care so much about social profiles.

    But that's a thing with social media; it creates an illusion of proximity, when in truth everyone is overwhelmed with all the information and all the social demands in the platforms

    And a lot of people are addicted to the phone, checking social media or talking with someone. Some exercise in the gym while being glued to the phone, not even activity takes them away from it

    And I was like that too, until I left social media. Now sometimes I'm grabbing my phone, opening the browser and thinking: I've seen everything I wanted to see, I don't have a reason to use the phone. And I put it down

    I didn't make case, I made my manoeuver to park the car. But I caught them off-guard, the one ahead hit the brakes and had to jump from the scooter. For a second I thought he would go against the car. They were trying to race through a gap they perceived, thinking I was going to always drive forward
