Jar to cover heat seal. Jar and cover are heat sealed and bead smoothed for a more reliable seal.
Safety vent. 3-10 psi opening pressure, self-resealing.
Color-coded terminal polarity. Provides easy terminal identification.
Heat sealed post seal. Non-corrosive polypropylene-to-polypropylene bond is as strong as the original material.
Interface between lead post and plastic sleeve. Coated with a viscous agent which ensures a virtually leak-free bond.
Modular steel tray. Easy to install.
Container and Cover. Polypropylene is standard. Flame retardant, UL94 V-0/28% L.O.I. is optional.
Space for positive plate growth. Space is provided so growth can occur away from post and cover seals to increase battery life.
High separator compression. Reduces possibility of loss of capacity and degradation of the plate-to-separator contact.
