Even if you only plan to maintain the battery, it's a better investment to buy an automatic multi-stage like the noco (but more powerful) or the PL2320 I brought up, even a 20 amp charger like that will work perfectly as a float charger, but it'll also charge quickly. Buying a 1A float charger, you're SOL if you need to charge a lot battery.
