Zinc chloride batteries are steadily becoming a thing of the past. While they are more efficient than the carbon zinc battery, they pale in comparison to the popular alkaline battery. However, just because there are more innovative batteries on the market, it does not mean that the zinc chloride battery is useless. All batteries operate in the same way; they move electrons from one area to another, creating an electrical current.
Zinc chloride batteries still have a wide variety of useful applications.They come in several traditional sizes such as AA, AAA and can be used in many electronic devices from portable compact disk players to miniature flashlights.The function of any battery is to increase the portability of an electronic device by not having to plug it into an outlet.
While zinc chloride batteries do outperform some batteries, they cannot outperform others. Compared with carbon zinc batteries, zinc chloride batteries have a 50% higher capacity, but are outperformed by alkaline batteries, which can have a 500% to 700% higher capacity. Zinc chloride batteries are less likely to leak than carbon zinc batteries.
The Zinc Chloride battery is a beefed up version of the general purpose Carbon Zinc battery. Variation in the chemical mix increases its capacity fifty percent. This kind of capacity makes it a better choice than Carbon Zinc because it can deliver more current. Zinc Chloride batteries are superior to Carbon Zinc in leak resistance.
Voltage decreases with each use until cutoff voltage is reached and the battery becomes useless. While Zinc Chloride batteries are labeled heavy duty, they do not withstand high temperatures much better than Carbon Zinc; however, they do perform better at low temperatures. Storage, or shelf life, is much longer than with Carbon Zinc batteries, but storing them at high temperature will shorten their life dramatically.
Zinc chloride batteries operate well at low temperatures. Their optimal range is between 0 degrees Fahrenheit and 160 degrees Fahrenheit. Their storage life is about two years. Unlike some batteries on the market today, zinc chloride batteries are not recyclable.
Compared to Carbon Zinc, Zinc Chloride batteries weigh twenty percent more, offer a fifty percent increase in service capacity, have the ability to sustain higher current drain and perform better at lower temperatures. When the Enercell Battery Guidebook was produced, Zinc Chloride batteries cost sixty percent more than Carbon Zinc, and were available everywhere and in many sizes. As with Carbon Zinc, price, availability and size range were the three advantages of Zinc Chloride over Alkaline batteries. Advances in technology and manufacturing techniques have eliminated these advantages by lowering the costs of producing alkalines in a wide range of readily available sizes. RadioShack takes great pride in our battery line and strives to provide the best quality for the price to our customers. As Zinc Chloride no longer offers a significant advantage and has significant disadvantages in cylindrical batteries, cylindrical Zinc Chloride batteries are no longer carried by RadioShack. The only Zinc Chloride batteries presently sold are lantern batteries.
