4u+ won't turn on

My tamagotchi showed me the screen where it says it's low on battery, so I took them out. I know it says that you shouldn't use rechargable batteries but I read that some people didn't had any trouble with that so I tried using them.

I put them in but it didn't turn on so I took them out and placed some alkaline batteries, it still didn't turn on.

The batteries are fresh and I even charged the other ones to see if they were the faulty ones, but it still doesn't turn on... I even tried putting the old ones back but no luck...

It's my first 4u+ so I don't know what to do

I also tried pressing the reset button but it's still not working

Is there any corrosion around the batteries or where you insert them? If so, that might be your problem. You might also want to try a different battery type, some Tamagotchi's are very wonky and some may like a certain type of battery while some might not.
