I have a battery carrying strap that works on any battery with top terminals. Mine looks like a 16" length of fan belt. On each end is a flat metal plate with a 5/8" (?) hole in it. Drop the plate over the terminals and lift. The plate locks onto the posts. Works well. Should be available at any auto supply place for a few bucks. See here, for example:
