    On a DS the light coming on for a couple of seconds and then going off is usually a sign that a fuse has blown. The GBA SP seems to be less obvious here, though it is still worth checking fuses (F1 and F2 on the silkscreen I think). After that you get to debug the charging circuit.

    Have the batteries you tried been charged before they were put in? Also I assume the charger works on other GBAs or an original model DS? If you do not have one then does it output the 5.2V?

    If a new battery didn't work, what I've done in the past is desoldered the fuse on the motherboard and just bridge it across using solder. Sometime, it's the fuses that are blown causing the system to not take a charge. They have this on YouTube as well.
