EUREKA NEC 260 C vacuum cleaner

I want to replace battery on EUREKA NEC 260 C vacuum cleaner.

The body is assembled with screws and several hidden internal clips.

Can someone help me identify the position of those clips and guide as to how can the battery be replaced.

I can't find anything useful on your model, but I see a similar one where the "clips" are substantial critters that DON'T un-clip, rather, you SLIDE the bottom off those "clips" perhaps that will help?
