HAMMOND RESEARCH LEADS THE WAY AGAIN

GravityGuardTM integrates with the active material, increasing surface area. The mono-silicate additive acts like “micro-sponges” that trap acid electrolytes, thereby minimizing the acid density gradient.

Real-World Testing

ON-SITE PRODUCT & PRODUCTION LINE VERIFICATION

After extensive research, development, and trials in our lab and manufacturing facilities, we implemented production line battery verification with trusted manufacturing partners around the world.
