AA lithium cells have a shelf life of up to 9 years, and they can last a far longer time than most other AA types in the right sorts of devices. Importantly for the health of your valuable electronics, lithium AA batteries don't leak over time, unlike many cheaper varieties.

The average alkaline AAA, AA, C, D, 9-volt or button-cell battery is made of steel and a mix of zinc/manganese/potassium/graphite, with the remaining balance made up of paper and plastic. Being non-toxic materials, all of these battery “ingredients” are conveniently recyclable.
In most cases, the battery will simply leak, but if the vapor pressure is high enough, it can explode. Alkaline batteries from reliable manufacturers are vented to allow built up heat and energy to dissipate. They can also explode when subjected to a high or persistent electrical current.
Lithium-ion batteries are more expensive than similar capacity NiMH or NiCd batteries. This is because they are much more complex to manufacture. Lithium ion batteries are not available in standard cells sizes (AA, C and D) like NiMH and NiCd batteries.
For example AA alkaline batteries typically have a capacity rating of over 2,500 mAh and AA NiMH batteries have rated capacities of only 1,200 to 1,900 mAh. Alkaline batteries stored at "room temperature" self discharge at a rate of less than two percent per year.

A. As batteries discharge—either through usage or gradual self-discharge—the chemistry of the cells changes and some hydrogen gas is generated. Alkaline batteries are prone to leaking potassium hydroxide, a caustic agent that can cause respiratory, eye, and skin irritations.
Ordinary Batteries: Regular alkaline, manganese, and carbon-zinc batteries are not considered hazardous waste and can be disposed of with ordinary trash. Other common single use or rechargeable batteries such as lithium and button batteries are recyclable, but access to recycling may not be available in all locations.
Why Alkaline Batteries Explode
When an alkaline battery heats up or is exposed to a strong electrical current, the energy releases hydrogen gas inside the battery sheathing. In most cases, the battery will simply leak, but if the vapor pressure is high enough, it can explode.Are dented batteries safe to use? If you don't notice any swelling, leaking fluids, or dysfunction when using it, it should be okay to use.
What is inside a battery? You'll get a real charge out of the answer. The average alkaline AAA, AA, C, D, 9-volt or button-cell battery is made of steel and a mix of zinc/manganese/potassium/graphite, with the remaining balance made up of paper and plastic.
The Duracell lasted 15 hours. The Energizer lasted 22 hours and 15 minutes. The Rayovac lasted 24-1/2 hours.
Can I store batteries in a plastic bag? Sure, as long as they're all the same type and age (new versus used). It's best to store them in the original packaging or to cover the terminals with plastic caps so the loose batteries don't contact each other and discharge.
AA lithium batteries are 1.5 volts batteries and as with all lithium chemistry batteries, are not rechargeable. AA Lithiums are manufactured by such brands as:Energizer, Duracell, Camelion, Hitech and Powerizer. They are not to be confused with AA Lithium Ion (Li-Ion) batteries.
The Duralock batteries were also part of an advertising campaign, which included both radio and television ads. They also allege that Gillette and Proctor & Gamble “conspicuously failed to disclose that the Duracell Batteries leak when not in use and the leakage can damage any device that the batteries are stored in.”
The short answer is that batteries rely on chemical reactions to work, and freezing temperatures slow or stop those reactions. In fact, cold temperatures prevent the kind of slow discharge battery ions do under room temperatures, as the engineering website Lithiumpros.com explains.
Self-discharge is a phenomenon in batteries in which internal chemical reactions reduce the stored charge of the battery without any connection between the electrodes. Self-discharge decreases the shelf life of batteries and causes them to initially have less than a full charge when actually put to use.
But car batteries usually go dead in cold weather mostly because damage done during the summer doesn't show up until the battery is more taxed. A cold battery has reduced cranking power, and cold temperatures thicken motor oil, making it harder to turn the engine over.
Lithium-ion batteries should never be depleted to empty (0%). According to one book, lithium ion batteries should not be frozen. Note that most lithium-ion battery electrolytes freeze at approximately −40 °C, which is much colder than the lowest temperature reached by most household freezers.
When the active material in the plates can no longer sustain a discharge current, a battery "dies". Normally a car (or starting) battery "ages" as the active positive plate material sheds (or flakes off) due to the normal expansion and contraction that occurs during the discharge and charge cycles.
When lithium-ion batteries are exposed to cold temperatures, their performance suffers. When cold, a phone battery can drain faster than normal, or it might say it has ample power remaining and then suddenly go dead. It's not just the battery, says Kwaterski.
Frigid weather can cause trouble with a car's battery. Cold temperatures wreak havoc on batteries because they slow the chemical reaction inside of the battery. Though batteries can function under myriad conditions, the cold weather tends to degrade high-quality batteries and may render subpar batteries useless.
Your phone is powered as the individual ions travel in solution from one pole to the other, but a cold temperature doesn't “drain” your battery, per se. They pass through the solution as solid lithium, which can really do some serious damage to the battery cell itself.
Turns out, charging your phone in your car could do more harm than good. Plugging your phone into a car's USB port could stall the charging and even damage the charger. Charging your phone could even drain a car's battery, especially if it's an older model.
Even batteries with a small voltage like commonly used AA and AAA alkaline batteries can start a fire under the right conditions. If the negative and positive posts of the batteries come in contact with something metal, heat begins to build.
A number of studies have shown that storing batteries in the freezer helps them retain their charge longer. Alkaline batteries stored at "room temperature" self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount.
DO preserve battery life by switching off a device and removing the batteries when it's not being used, and is not expected to be used for extended periods of time. DO practice proper battery storage by keeping batteries in a cool, dry place at normal room temperature.
In order to store your batteries correctly, you should keep them in their original packaging, or place them in a plastic container – NEVER store batteries inside equipment. Keep batteries in a cool location with low humidity and make sure they are aligned in the same direction.

Storing them at lower temperatures will slow their self discharge rate dramatically. NiMH batteries stored at freezing will retain over 90% of their charge for full month. So it might make sense to store them in a freezer. If you do, it's best to bring them back to room temperature before using them.
Even batteries with a small voltage like commonly used AA and AAA alkaline batteries can start a fire under the right conditions. This can happen easily if a penny touches the uncovered end of a 9V battery, or if a paper clip or other common metal object comes in contact with more than one AA battery.
Storing batteries in a freezer can't actually charge them because there is no power source where the charge will come from. So storing them in a room with low temperature will extend the period retaining their charge. To make it clear, storing the batteries in the freezer doesn't help recharge batteries.
