Trickle charger

Hi folks. Will a 3w solar trickle charger maintain my two agm batteries? On the dash behind the windshield?

If not what will, inexpensively? I plan on solar roof top possibly next year so hate to waste the money. Parking it out of state for two months at an RV storage place.

You could always put two of those solar chargers on your dash, and double your charging capability...

But..... do I need two or three 😊. What’s typically the no-load discharge rate for two Agm batteries?
