It is always wise to buy and store rechargeable batteries in case of power outages as a result of adverse weather conditions such as storms. In fact, scientists like Elon Musk believe that the future of energy lies solely in renewal energy relying on rechargeable batteries. However, the life of these batteries varies from user to user. Some of the most significant factors affecting the life of AA and AAA batteries include the quality as well as the type of battery, the application and the frequency of use of these batteries. There are external environmental conditions such as temperature and humidity that sometimes reduce the life of the batteries too.

1: Quality.

When it comes to buying batteries, retailers insist on quality over quantity. In simple terms, a higher quality battery will exhibit longer life. It is better to stick to a trusted brand of battery despite its price. Some retailers hike the prices of batteries in a move to convince the customer of its quality. As such, it is advisable for customers to do thorough research into the batteries available on the market in order to get good value for their money.

2: Type

There are four types of batteries under the AAA battery category. These include the standard battery, alkaline battery, lithium battery as well as the rechargeable batteries. In most standard applications, the standard batteries usually have the shortest life span. Alkaline and lithium applications exhibit slightly longer life spans compared to standard batteries. Rechargeable batteries by design last the longest and are most preferred among many customers. When making a decision on which type to purchase, it is important to note that single use lithium and alkaline batteries can power equipment for two hours and then run out, while rechargeable batteries powering the same equipment could only go for an hour. The task at hand should determine the type of battery to buy.

3: Use 

The life of AAA batteries is entirely dependent on what they are being used for. As earlier explained, standard batteries have the shortest life span compared to the others. However, rechargeable batteries cannot be used in appliances such as flashlights, as in this instance they would continue to discharge even when not in use. Being continuously recharged and discharged tends to significantly reduce the life span of batteries.

4: Environment 

Most batteries come with a caution sticker on the box they are packaged in. It usually prescribes a range of environmental conditions that are safe for use. Any other temperature range or level of humidity tends to reduce lifespan, as these conditions interfere with the chemical composition of the batteries. However, particular types of batteries require different conditions - for example, lithium batteries work best at extremely low temperatures. These type of batteries are prescribed for use during winter where other types of batteries fail.
