Yes, they are. And you can mount them upside down if you want. Try that with your "wets". :B
Guess what happens if you forget to recharge them to 0.5a/100AH at 14.x volts until amps taper that low. (see that guide and the other brands' guides, same thing.) You need an ammeter and a charger that will hold 14.x volts for as long as needed to get that done, which many chargers/converters can't do.
Also AGMs can be mounted sideways but not upside down.
Hmm ... we've been over some of what you say above, before.
Keeping lead acid (liquid or AGM) batteries as close to fully charged as much as possible is what makes them serviceable for the longest possible time. I've seen nothing in print from the experts as to why voltages above 14 are required - if one has the time to let them fully charge up using less than 14 volts.
My 2nd set of AGM RV batteries in 14 years is doing as fine as the 1st set did (for their first 8 or 9 years) using only the stock 13.6-13.8 volt converter in the RV and the engine alternator when traveling to charge them. While in storage both sets of AGM batteries were/are continuously hooked up to the converter, since the RV is plugged in all the time during storage.
I'm still looking for my first technical paper detailing the reasons why voltages greater than 14 are required to fully charge lead acid batteries - assuming that an ammeter shows the batteries have reached the low 0.5 amp fully charged current acceptance rate at whatever charging voltage was used.
