still stuck on stock battery cuz im too scared to explode my wii u gamepad

mine dies within like 1 or 2 minutes from me taking it out of the charger and im too poor and stoopid to get a better battery

Upgrading the battery was the first thing I did, the old battery was in pretty bad condition!

I got the exact same battery, it's great!

by any chance did the new battery help the gamepad range? my gamepad has some issues with disconnecting
