If it is a True AGM battery there is NO effect on the battery during
Inverted operation

This from the Internet:


A relatively new type of sealed battery construction that uses saturated
absorbent glass (boron silicate) mats between the plates instead of a
gelled or liquid electrolyte. AGMs batteries are more expensive than the
flooded (liquid) variety but offer a number of advantages.

Since all the electrolyte (acid) in AGM batteries is contained in the
glass mats, it can't spill, even if the battery is broken. Being thus
non-hazardous, AGM batteries are cheaper to ship. Additionally, since
there's no liquid to freeze and expand, they're practically immune from
freezing damage.

Nearly all AGM batteries are recombinant, which means that the oxygen
and hydrogen recombine inside the battery. Recombinant batteries use gas
phase transfer of oxygen to the negative plates to enable recombination
back into water while charging, thereby preventing the loss of water
through electrolysis. The recombining is typically more than 99%
efficient.

AGMs have a very low self-discharge - from 1% to 3% per month is usual.
As a result, they can sit in storage for much longer periods without
charging than standard batteries.

That is of course if the battery is disconnected in storage.
