These fakes are very hard to detect visually. Both fake and genuine HG2’s have four spot weld points on top and free-floating (not glued on) top ring insulators. The fakes have a slightly wider ring around the battery near the top but that will be very hard to see without having a genuine HG2 for comparison.

There’s no other way to detect the fakes than internal resistance (IR) or discharge testing. The HG2 has an AC IR spec of <=20mOhms. My genuine ones measure around 15mOhms. The fakes measure about 35mOhms, indicating that they will have huge voltage sag and a low current rating.
The fakes perform MUCH worse than genuine HG2’s, DO NOT USE THESE FAKES!
