Please note: battery replacement should be carried out by a responsible, considered and competent adult!

Lithium batteries are dangerous!

If you are someone who struggles to use basic hand tools, is uncoordinated, or cannot follow basic instruction then do not attempt this!

Fumpa takes no responsibility for your stupidity. If you decide to continue with the battery replacement process, then don't be an idiot. Take your time, use your brain, and respect the battery.
