As an aside there seems to be far too many instructables like this, a video and multiple pages of instructions on buying a Chinese power supply module and connecting it.
Also note that not all of these modules are suitable for charging batteries; power supply circuits have to be specifically designed to allow voltage to be applied to their outputs without being destroyed

2. Can I directly connect these wires to SLA 12V 7Ah battery? Then the charging time would be 35mins (7Ah/20A=0.35h)?
Am I the only one that has spotted this? 0.35 hours is not 35 minutes; it's 21 minutes.
All, thank you very much for your help and advice on this topic and also for links to videos and articles, though I didn't go about trying it.
I dropped the idea of using that PSU conversion thing. I spent whole day in the garage and managed to find its own charger. All is well now
Cheers
