Charging a 12v starter box battery help

Im looking for a simple way to charge up my starter box battery. I have currently been using my e-station charger but I will be needing that now for charging my lipo packs for truggy and it takes forever to charge the starter box battery anyway.

So I have this 12v 1amp trickle charger for automotive/recreational batteries (one of those cheapo plug in the wall tranformer looking type) that I have no other use for so I was wondering if I could use that to charge the starter box battery?

Here are the specs on the charger:

1A trickle battery charger for small 12V lead-acid batteries; warms larger batteries
Reverse hook-up protection helps prevent battery and charger damage
Solid-state circuitry provides optimum performance
Copper-wound transformer for longer life
Conveniently plugs directly into a wall outlet
12' output cables with 50A clamps <<-- Which I would solder bananna plugs instead of.


Here are the specs on the starter box battery:

12V 7.2AH Gel Cell Battery
