In this video I'm showing the Panther 12 volt battery charger. Typically used for charging car batteries but can also be used for smaller 7 amp hour batteries often used in off-grid applications and UPS. I've also tested it on my deep cycle 100 Ah solar master battery which I normally keep topped up with my solar panels.

When I called Panther, they were unable to tell me if the battery charger would work with the deep cycle battery. I wasn't sure either since the full charge voltage of a car battery is generally around 12.7-13 volt while the full charge voltage of a deep cycle is usually more around 14 volts. It seems to work just fine though :)
