I posted this a month ago on another forum when a comment was made that their batteries were one of two that had UL ratings.
Here are just samples...
Trojan Trillium- UL1642 (cells)
Elite GBS - UL1642 & UL1973
Battleborn - UL2054
Victron - couldn't find
Relion - UL1642
Lion Energy - couldn't find
UL1973

UL1642

Some have these listed also...
