Charging deep cycle with Century charger ok?

[Dkoy]

I have a century 6/12v 6/2A charger, ones you have to clamp on. Is it safe to charge my deep cycle on it? I have a 27 deep, guessing 100 amps for my deeps, therefore guessing with the 6amps, I would need to charge it for about 16 hrs for a full charge? I dont' have a battery indicator, but on the charger there's an indicator on it, but it runs only when you plug in with the battery, which I dont' understand how to read. Any input on how I could charge or how I charge this.

You have it right. About 16 hrs to charge it fully. Go ahead and use the century. It will work OK.

It be better if you had a deep cycle charger.
