While its nice you have your opinion, you clearly haven't looked around at the problems people have filling or even checking battery banks. I have 4 T-145 Trojans weighing 290lb. that are nicely tucked in a roller shelf that I would never pull out over my feet without external support, and even then I can't see or fill the rear two without removing the front batteries.
So to the OP.. Yes if you can't get to your batteries they ARE worth it. Just make sure you remove the batteries from time to time and make sur the valves are clear and haven't crudded up, preventing the fill valve to work.
