AGM (with reversed terminals which makes it difficult to source)
Any smart charger (not a trickle charger) that has a dedicated AGM setting (I personally use a NOCO Genius 5)
Look on the rear passenger side corner of the engine bay and you will see a removable panel with a - (minus sign) on it. Under that cover is a negative post used for jumping or charging. Once you know where it is you can sneak a charger clamp in without removing the cover and wearing out the plastic clips. In the front passenger corner there is a roughly triangular fuse box cover with a red + (positive symbol) on the cover. Remove the cover and directly under that symbol is a small post with some red paint on it. That is the positive terminal. If you don't wait until the car "goes to sleep" about five minutes after shutting it off you might hear a relay click that sounds an awful lot like a spark when you turn on the charger. That's normal but I prefer to wait until the systems power down.
Also, every time you connect to your GV80 remotely it powers up most of the vehicle systems then waits for a command, which takes a considerable amount of power.
I wouldn't be too concerned about that message. We regularly leave ours for a week or two and have only received that message once on day 15 of a trip. When we returned on day 17 it only took about an hour on the maintainer to bring it back to full charge (which is only around 80/85% on the connected services monitor for ours. Other see higher and lower) never checked to see what the app read when it sent the message but it must not have been that low. Maybe someone else know that answer.
