The final step was to add Velcro to the unit.

What about this charger? There is one available to me locally used.

Schumacher se-82-6

*On edit I see it is a manual charger.

For now, I would simply stick with your 2A charger, as even that will recharge your battery sufficiently if you leave it plugged in when you're not driving.
EVs: 2 Wht/Blu SE Prem., '13 Tesla MS85, 3 156v CorbinSparrows (2 Li-ion), 24v EcoScoot(LiFePO4)
EV Conv: 156v '86 Ram PU, 144v '65 Saab 96
Hybrids: 48v1kW bike
ICE: '88 Isuzu Trooper. Mothballed: '67 Saab (orig.owner), '76 MBZ L206D RHD RV

Depending on the model, the Ship N Shore appears to have settings for AGM batteries, so the charge and float voltage should be correct. While not a true 'smart charger' it would probably take pretty good care of your battery

If you're going to pay $60 for the Ship N Shore new though, this one would be a better choice: http://www.ebay.com/itm/VMAX-BC12M248-1 ... SwOtdYUbEk
It's a true fully automatic, sealed, temperature compensated smart charger which you can leave plugged in 24/7 without harming anything

I asked because there is a used Ship N Shore for sale here and I see it is automated and that it is rated for an AGM battery. But I really will not need the remote heating system till Fall. That is if we are not entering a new ice age, as seems to be the case here this week! :)

So I bought a battery charger. I bought this one because I needed a battery charger in general. I am not thinking it would be the proper one for my AGM battery. It would be nice if it was but I bought it because it was a good charger for the price $15. I can still buy another charger if this one will not suffice.

Its a Schumacher SE-5212A

I read this bit about my charger:

"I did a little testing with it last night and put it on the 10A and it appeared to provide a current of roughly 8A then scaled down to 2.5A until reaching 14.6 V over about 2 hours and then floated with less than 2A intermittently at 14.8. I then took the battery off and put it on a tender which provided a current of about 1.25A at 13.8V. This appears to meet the specs of what I have found online."

If this testing the individual did is true does this charging profile work with the AGM battery I own?

Those voltages seem a bit high for AGM. A bit high for a wet cell lead acid too, for that matter. Anything over 14.4 is boiling off electrolyte thru hydrolysis.

You could put a large diode or two in series and that would drop the voltage that the battery sees by ~ .7 to 1.5 V, then it could still be used but would prevent the over-voltage.
