Power supply as a charger

[Hiks]

In another hobby i have i'm wanting to connect a charger up to charge three different things at the same time, the charger itself connects to a power supply with banana clips these can be £35+

Just wondering if i'd be OK to connect this up to an old PSU using the psu trick. I'll throw some details from the manual below...

Connect the input leads to the 12v supply, (normally a 12v battery, but a high

quality power supply capable of supplying up to 6.0A can also be used). Connect the

RED crocodile clip to the POSITIVE terminal on the battery and the BLACK clip to the

NEGATIVE. The orange Power On/Off LED will glow.

Connect the charge lead(s) to be used into the spring sockets on the end of the charger,

ensuring that the polarity is correct.

Wold it be OK to hook it up to the 12v of an old psu? any more details needed?

It would be charging NiCad/Ni-MH batteries and it might be on through the night as well so if someone could reassure me its exactly the same as one i'd buy and it isn't going to blow up then that would be great

Don't quote me, but I don't think its as simple as hooking a battery up to a power source to get it to charge. I would imagine that you'd need some kind of diode at the very least to ensure current only travels in one direction

lol everyone is a bit like whoah dunno about this one

This is what i'm thinking to hook up, its a .pdf but has images etc

my experience is wiring LED's as well so i may just be best forking out the 35 quid.
