This is a handheld vacuum cleaner with a simple circuit inside. I’ve charged it fully for a good while and also tried decharge-recharging it but no joy. All it can manage to do is ticking the engine which is not powerful enough to get it on full rounds and working. I have contacted the producer and they said they don’t have batteries available for this item. Is there a way I could find out if it’s the battery or something else? I find it a waste to put this in the bin and buy a new one.
P. S. I have a video but it doesn’t seem like I can upload videos here.
Update #2: I’m not sure if the contact is made but here’s how I’m testing and still no joy. I have a feeling that I’m making a mistake somewhere.
