Hold the device firmly between two fingers. Be sure you aren't holding down the top of the device; the circuit board will slide out of the shell through that end.

Snip the wires using a wirecutter. Be careful not to nick the battery and cause battery acid to leak everywhere. That would be unfortunate.

You should specify the battery type. The plastic wrap on the photo shows 180mAh capacity and it has to be rechargeable, unlikely to be lead-acid and therefore should not leak acid. Button cell batteries aren’t usually rechargeable so please explain exactly what battery type you used - manufacturer, model no. etc. Since you suggest cutting the wires, how do you reconnect to the new battery? The photo is inadequate to show how this is done. If the battery is a replaceable button cell, I would not expect it to be in an apparently sealed plastic bag.

It’s a 502025 Li-Po battery. Capacity doesn’t matter, but you can find them at 200mAh. The replacement batteries come with wires.
