Toyota Sienna hybrid battery questions

My Sienna feels weak on hills when it is loaded. Is that the battery?

A fully loaded van on a grade in summer heat is working hard, so some of that is normal. If it is a change from how the van used to feel, have it tested rather than assuming either way.

Should I have the hybrid battery cooling checked on a newer Sienna?

Yes, especially if you carry pets or load the cargo area to the roof. It protects a healthy pack; it will not revive a degraded one.
