Default Li-Ion Rechargeable cells - charged by small solar panel *Solution needed*

Hey, I bought lately couple of ready made flash lights charged by small solar panels with Li-ion Rechargeable Button LiR2032 3.6V Cell Battery in each of them. Took them a part and Now I would like to merge/combine them both to get higher voltage output and of course use both panels at the same time. Anyone have any idea how to do it? Need help with it if anyone willing to give a hand please.
Paid for both 2 ...I hope it was good purchase. lol I would like to use it for further experimenting with laser burner... kinda solar powered laser burner (if that's even possible)

Please help!

Bad idea. If you put more voltage into either the battery or the LED, it will damage them. You can charge the battery more quickly be putting the panels in parallel, but if this is the Chinese crap I think it is, it's not even worth your time.

You could make the charging circuit found here. Then just run your laser from the outputs.
