Now I am not sure what you have for auto parts stores but if you can find one you can get a cheap 12v battery charger..

So actually now that I think about it the short and safest answer is NO you need a proper charger for it.

Using a DC supply will charge it but with no over voltage protection, no control, nothing to switch to trickle when the battery is nearly charged... not a good idea.

Yep. You over charged them and boiled it dry. Lucky you didn't get hurt.
