My 3ds won't turn on after battery replacement

[kchorro2012]

This console was bought in 2018, never had any issues even after hacking it. Around 3-4 months ago I noticed some charging issues and then realized the battery was swollen, so I got rid of it. I didn't get a replacement battery until last week because it simply wasn't a priority to me. The new battery (an alternative one) worked immediately with no issues, so I charged it completely. I used the console sparingly for about a day and now it won't turn on at all. Last thing I did was putting the console to sleep while I was playing a DS game on my R4. Didn't think much of it until night, when I realized the console was discharged. I tried to charge it and turning it on, but only the orange LED turns on. I tried removing the battery, the micro sd card, but nothing works. I can only think the battery is the issue, but I haven't been able to get a hold of another one to compare (they don't sell them in my city, I actually bought mine off a website similar to amazon). I really want to make sure the battery is the issue since sending it back is a real hassle.
Edit: This is a new Nintendo 3ds xl.

While the battery is likely the issue, you’re not going to know for sure until you’re able to try a different one. You likely discharged it to 0 while you left it sleeping with a flash card running.

Do you have any friends who might have a console and let you try their battery?

I might be able to borrow another 3ds by next week. I don't have a multimeter to check the battery either. At least I have until March to send it back for free.

The battery oem?

No, the replacement battery is an alternative one, I haven't been able to find original ones in my country (and original ones are too expensive to import due to taxes).

It is best for you to get an OEM one.
