went well. Remember to drain your battery first just for better safety.

Mein Rat

you can follow the advice from here: https://www.youtube.com/watch?v=ruG2Nh-r..., i.e. use a string to "cut out" the battery from the container.

It worked pretty well and so you don't have to take everything apart because you don't need to use the adhesive liquid remover a lot.
