Battery on the 4runner is dead since I haven't driven it in quite a while. I think it's time I get a battery charger that will maintain the battery when it sits. What are the features I should be looking for? I want to spend less than $100.

 

My brother uses something like this to keep him 5th Wheel batteries charged up.

we have something like this in the garage to charge up batteries, Pop's has the big one.

Yeah, I want something more than just a battery tender/maintainer. I want the whole engine start capability thing too.

 

The second link will do that.

For something more heavy duty this might work.

I would try to find a used one on craigslist or ebay.
