Very Inexpensive Battery Maintenance Charger
1.0 ampere output. 13.8 volts regulated charge limit. This unit is good for 100 amp hours worth of batteries. IMO the voltage is a tad high for a high antimony RV battery with temps 60F or higher but ...

Well an IR thermocouple could not define one-tenth of one degree difference between ambient temperature and both copper battery posts, so I'm not going to worry myself sick over the issue. This isn't like dealing with nitroglycerine where one small boo-boo makes for a spectacular result.
The accumulator is constructed of pure lead plates, right? The mats have 1.300 specific gravity electrolyte soaked into them, right? The construction and chemistry is the same as any other AGM, do you disagree? If the plates were alloyed with something weird like palladium or bismuth, I would be very cautious about deviating from OEM specifications. But they aren't. It waddles, quacks and has feathers, so it is indeed an AGM battery and it can well tolerate 13.75 volts float up to around 30-32C. These critters live day in and day out in RV's and emergency vehicles, where charging system voltage ranges from 13.8 - 14.4
