Are carbon zinc batteries safe?

Is there a difference between alkaline and carbon zinc batteries?

The difference between these two types of batteries that would directly impact the ordinary user is battery capacity. Although zinc chloride batteries have a higher capacity compared to the older zinc carbon battery, the capacity of alkaline batteries is many folds over the capacity of both types of zinc batteries.

Zinc-alkaline batteries are widely used in light drain and heavy drain applications including radios, flashlights, cameras and toys. Nickel-zinc batteries, which are rechargeable, can be utilized in power tools and automotive applications.

After the testing was completed the following results were recorded: The Duracell battery lasted the longest, 101 hours and 20 minutes; Energizer battery, second, 99 hours and 17 minutes; Eveready battery, third, 28 hours and 30 minutes, and last but not least was the BA 30 batteries, 25 hours ad 58 minutes.

At its invention, it was restricted to laboratories due to its liquid content. The first dry cell, also a zinc-carbon cell, appeared between 1886 and 1888, and was developed by Karl Gassner.

The difference between a cell and a battery is that a cell is a single unit that converts chemical energy into electrical energy, and a battery is a collection of cells.

Damaged or recalled batteries, including when in a device, must not be carried. Batteries allowed in carry-on baggage include: Dry cell alkaline batteries: typical AA, AAA, C, D, 9-volt, button-sized cells, etc. consumer-sized lithium ion batteries (up to 100 watt hours per battery).

“Spec-Pure” (spectroscopically pure) grade is available for carbon (graphite) rods with impurities equal or less than 2ppm (single element 1 ppm or less). Typically the impurity level is more likely 1ppm or less.

The practical difference between Lithium batteries and Lithium-ion (Li-ion) batteries is that most Lithium batteries are not rechargeable but Li-ion batteries are rechargeable. A lithium battery should never be recharged while lithium-ion batteries are designed to be recharged hundreds of times.

A battery contains electrochemical cells that can store chemical energy to be converted to electrical energy. A dry-cell battery stores energy in an immobilized electrolyte paste, which minimizes the need for water. Common examples of dry-cell batteries include zinc-carbon batteries and alkaline batteries.

VOLTAGE: If you decide to replace alkaline with lithium, its important to check the replacement has both the appropriate voltage and type/size. Energizer e2 lithium AA batteries produce 1.5 volts, so they can be used to replace any regular alkaline AA units in most cases.

Lead-acid batteries are capable of being recharged, which is important for their use in cars. Discharging the stored energy relies on both the positive and negative plates becoming lead(II) sulfate and the electrolyte losing much of its dissolved sulfuric acid.

The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, instead of the acidic ammonium chloride or zinc chloride electrolyte of the zinc-carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes.

For MP3 players, they will provide up to four more hours of use. When dealing with digital cameras, lithium AA batteries can last up to seven times longer than an alkaline battery. Cost: Since lithium batteries outperform and outlast most alkaline batteries, they are often priced at substantially higher prices.

Chemically, a typical alkaline dry cell battery has a zinc anode and a manganese dioxide cathode. The electrolyte is a non-acidic basic paste. A typical electrolyte used in alkaline batteries is potassium hydroxide. The electrolyte surrounding the anode mediates the chemical reaction between the anode and the cathode.

A “dry-cell” battery is essentially comprised of a metal electrode or graphite rod (elemental carbon) surrounded by a moist electrolyte paste enclosed in a metal cylinder as shown below. The alkaline dry cell lasts much longer as the zinc anode corrodes less rapidly under basic conditons than under acidic conditions.

AA lithium batteries are 1.5 volts batteries and as with all lithium chemistry batteries, are not rechargeable. They are an ideal alternative to AA alkaline batteries, with far superior performance. AA Lithiums are manufactured by such brands as:Energizer, Duracell, Camelion, Hitech and Powerizer.

Rechargeable batteries should not be used in some of the devices because they do not supply the proper voltage needed to run products. They will not ruin the devices, but most will not work properly. New and fully charged Rechargeable batteries of the same size only put out 1.2 Volts.

Zinc carbon cells have a short shelf life as the zinc is attacked by ammonium chloride. The zinc container becomes thinner as the cell is used, because zinc metal is oxidized to zinc ions. When the zinc case thins enough, zinc chloride begins to leak out of the battery.

Only batteries that are specifically labeled “rechargeable” should be recharged. Any attempt to recharge a non-rechargeable battery could result in rupture or leakage. We recommend that you use NiMH Duracell rechargeables. Paired with one of our different chargers, they can be recharged hundreds of times.

The result has mostly been the same—you are much better off buying less expensive batteries, because there is generally no measurable difference in quality or performance. (e.g., AA Alkaline Batteries made by Duracell measured against AA alkaline batteries made by Powerhouse Two).

The Big Battery Myth is that refrigeration makes them last longer. And it does, though in most cases not by much: Alkaline batteries discharge at less than 2% a year. And rechargeable nickel-cadmium batteries lose a few percentage points daily.
