As far as the batteries being heavier from Raion Group, that probably means more lead. The spec sheets should have enough info to tell. I have also noticed the batteries from the Rain Group are also a bit less expensive than from other places.

I don't know if I was only pricing for one device, and getting it wrong that way. Or if pricing outside business hours are different. ;) I have updated that post. Battery Wholesale also mentioned the Zeus brand, slightly heavier than the original quote. I went with Raion group. Same weight as the Zeus brand, but about $71 more (+22%) delivered. Thank you. -- Dan Langille dan at langille.org
