Anyone have a suggestion for a solar battery maintainer you've used and liked? I'm going to start keeping my hybrid away from my house without access to electricity. I'd really rather not have to take the battery with me every time I drop it off only to need to hook it all back up for the start of the next trip. It'll be in a secure place so I'm not worried about the battery getting stolen or anything, but I don't want to end up with a dead battery that won't charge. Just looking for suggestions. Thanks.
