I have a '96 ES300 with a Sears Die Hard battery. If I use a cigarette lighter splitter with 3 sockets and plug something into each one (for example a GPS and 2 cell phone chargers), would that cause such a drain on my battery that it would die? I'm only planning on using it while driving on vacation. I had the alternator replaced recently and the shop didn't say that I needed a new battery.

What you plug in are not drawing much current and while driving alternator is active. Some German cars like Audi I had, if battery is loaded too much it'll shut down devices to
conserve battery capacity for next engine start.
