Max Battles are co-op fights at Power Spots, which are their own map points rather than Gyms or PokéStops. The reward is a Dynamax Pokémon. It is the newest system in the game and the thinnest-covered.

When they happen

Both land on the calendar, and the Max page lists what has been announced. Max Monday shows as an expected row until Scopely names that week's species.

Dynamax this season

The Forever Forward season post names these:

The game's data files carry no Dynamax roster and no Max move data, so the species above are the ones an official post named, and this page does not describe Max Moves, Max Particles or Gigantamax mechanics. When Scopely publishes them, they will be here.

Questions people ask

What are Max Battles in Pokémon GO?

Co-op fights held at Power Spots, and the reward is a Dynamax Pokémon. They are the newest system in the game and the one with the least published about it.

What is a Power Spot in Pokémon GO?

Its own kind of map point. A Power Spot is not a Gym and not a PokéStop, so a Max Battle happens somewhere a raid never does.

Are Max Battles the same as raids?

No. Different map points, a different fight, and a Dynamax Pokémon rather than a raid boss encounter. Raids stay on Gyms.

When is Max Monday?

Mondays, 6 AM to 9 PM local time, with one Dynamax species featured at Power Spots all day. It runs weekly, so the calendar carries it as an expected row until Scopely names that week's species.

What is Max Battle Day?

The Max system's version of a Raid Day: announced, a few times a season, rather than weekly. Announced ones land on the Max Battles page.

Which Pokémon are Dynamax right now?

The Forever Forward season post names Electabuzz, Magikarp, Feebas.
