The basic design of "VINNIC" Extra Heavy Duty battery is the same as the Super Vinnic Heavy Duty battery. Both types utilize manganese dioxide for the positive material, zinc for the negative material.

Both Vinnic Extra Heavy Duty and Super Vinnic batteries deliver top performance and excellent durability in general application.

Particularly, this kind of general purpose zinc chloride battery is less expensive than other manganese batteries, so it is more economical where several batteries at once are required.

In the fourth-coming year, Vinnic is considered to be at the forefront of addressing potential environmental concerns in the battery industry. Our improved mercury-free Green Pack batteries are one the outcomes in response to the environmental concerns.
