I'm really surprised to hear people say this. I've used split washers and Bellville washers on batteries for 25+ years, and they've done me well. I also can't recall ever encountering any bolted battery connection on any commercial product that didn't have a lockwasher. And think about it - have you ever seen any case in a vibrating, lurching vehicle where there wasn't something resilient (a head gasket for example) that lockwashers weren't used? One thing to be careful of is that you want your lug in direct contact with the battery terminal itself, with no washers between them to add resistance. You add the washer(s) between the fastener and the lug. Some discussion too of terminal glop. With flooded batteries, I normally use petroleum jelly to exclude air and moisture. Many years ago I got a free can of some kind of Cosmolene-like spray with an order of USBMC golf car batteries. That stuff worked well too and was easy to use. The key, I think, is that I put the goo on AFTER tightening the connection, not on the mating contact surfaces. (Though I've known people who DID use grease on mating surfaces.) I don't think I've ever bothered with grease when using valve regulated batteries, however. Maybe I should have, but nothing bad has yet happened. To get back to the point, I'm pretty skeptical about washerless battery connections. If you try this, please make sure you keep us updated on how it's going over time. For now, though, I'm sticking with lockwashers.
