I'm passing along some info that I received, absolutely know nothing about the batteries.

They may be complete junk, and for $27 for a VFR battery, the odds are good. But for someone looking for a
battery for a project bike on the cheap, these may do the trick.
Again, Sgt. Shultz and I, know nothing, nothing.
