Will not be driving the car for almost a month. What concerns are there for the charge of the battery? Need to make sure the car starts when I return from vacation

 

You can get a resonably inexpensive battery tender or I think they are called battery minder too.

 

Use the Enform Remote to start the car remotely once every week.

 

Here's one at Amazon:

 

Thanks for the suggestions. I will be out of the country and so it would be interesting to used the Enform app. The battery tender is a good option but the car will be in a driveway. I Amy need to get human intervention...

I was wondering if the battery would hold a good enough charge for that period. It would be in the spring in So Cal.

 

I am sure the 12V battery will hold a charge. You can buy a solar based charger with a ODB2 plug. I am new to hybrids so I am not sure how the hybrid battery will hold up.
