Not possible to change to top? They are not soldered to battery?

Hi there. The main board has two tiny holes where the battery pole must be solded. It is the only way. You need also the electric welder to remove the old battery.

What is an electric welder? Lol Cant you just pry old off with a screwdriver and then solder those on to the new ones? Also, amazon sent too short ones, same spec, but too short lol
