Safety Tips for Buying Batteries and Chargers

Batteries are an integral part of everyday life, converting stored chemical energy into electrical energy. From remote controls to torches, clock radios, cordless tools, and smoke detectors, many items rely on battery power in order to operate. Batteries come in a wide array of shapes, sizes, and types, each designed for use with specific devices. The lifespan of batteries tends to vary depending on quality and frequency of use. Batteries may be disposable or rechargeable. Disposable batteries are designed to be used once and then discarded, while rechargeable batteries are designed to be used multiple times. In the case of rechargeable batteries, buyers should also invest in a battery charger.

When purchasing batteries and chargers, buyers should consider the various types, familiarise themselves with battery chargers, understand the proper measures to take to ensure safety, and learn how to store batteries properly. Batteries can be bought from supermarkets, electrical shops, and many other bricks and mortar retailers. They can also be purchased online at marketplaces, such as eBay.

Types of Batteries

There are various types of batteries, ranging from quick draining laptop and digital camera batteries to slower draining batteries. Although battery size is an important factor, buyers should also bear in mind that of the various types, some hold a charge better than others.

Disposable Batteries

There are various types of disposable batteries including alkaline , lithium , and zinc carbon . These batteries are purchased fully charged and are ready for use. Once drained, the battery is then discarded. Disposable batteries are often preferred for their low cost and ability to hold a charge for long periods of time when not being used. They are well suited for radios, torches, and smoke detectors that use little power. Disposable batteries have an average shelf life of five years, making them ideal for storage and use in emergencies.

Rechargeable Batteries

There are several types of rechargeable batteries including lithium ion, nickel cadmium (NiCad), and nickel metal hydride (NiMH). Unlike disposable batteries, rechargeable batteries are able to restore their power once drained. These batteries can be charged numerous times and provide many years of long-lasting use. They are best suited for heavy-drain devices such as digital cameras, mobile phones, cordless power tools, and laptops. The table below lists the popular types of rechargeable battery, their features, and a list of their respective applications.

Although they offer many benefits, the disadvantage of using rechargeable batteries is their price and their need for frequent recharging. If left unused, rechargeable batteries tend to self-discharge at a faster rate than their disposable counterparts, requiring users to recharge the batteries before use. Buyers planning to invest in rechargeable batteries should purchase a compatible charger.

Safety Tips to Consider for Batteries and Chargers

When buying batteries and chargers, buyers should take into account several safety precautions. These help to protect the battery operated device from becoming compromised.

Check the Quality of Batteries

The quality of the batteries should always be considered when making a purchase. Although the low cost of batteries tends to draw buyers towards a particular product, batteries that do not contain important details on the packaging, such as the type of plastic and cells used, should be avoided. Buyers should purchase batteries that use ABS plastic and are brand new A-grade cells manufactured by reputable companies. These components guarantee high performance.

Check That Batteries Have Safety Components

Some battery types, such as those for laptops, are made with special safety components. These components include thermostats on cells, which are designed to monitor the temperature and an integrated safety mechanism on the printed circuit board (PCB). As heat levels reach dangerous temperatures, the safety mechanism disconnects the battery. If these components are missing or compromised, it can result in damage to the laptop or to the laptop's user.

Consider the Temperature of Batteries

In order to function properly, batteries should be at least 4 degrees Celsius. In general, batteries do not work as well in hot or cold weather. Battery capacity tends to decrease as the temperature goes down and increase as the temperature goes up. Although a temperature increase may seem beneficial, this causes the battery to drain at a quicker rate. For a longer lifespan, buyers should ensure that their batteries are kept at room temperature.

Check the Date Stamp on Batteries

For optimal performance, buyers should only purchase batteries that are less than six months old. The majority of batteries contain a date stamp that is engraved into the cover of the battery and can offer important information. The first two characters used for the date stamp are a letter and a digit. The letter indicates the month in which the battery was manufactured: "A" stands for January, "B" for February, and so on. The digit specifies the year of manufacture, where 9 stands for 2009.

Avoid Contact with Metal Objects

Batteries should always be stored separately from items that contain metal. Objects such as coins and paper clips can cause the batteries to short circuit and heat up if kept in close proximity.

Ensure Chargers Do Not Overcharge

When purchasing battery chargers, buyers should consider the various types. Smart chargers recharge batteries at a faster rate than other types, allowing them to regain their full charge within several hours. As a safety precaution, these chargers contain an intelligent microprocessor that is able to register when the battery is fully charged, allowing the charger to slow its rate of charge in order to avoid overcharging. Overcharging can shorten the lifespan of the battery.

How to Store Batteries Properly

Batteries tend to work best at room temperature. Therefore, they should also be stored at this temperature. Overexposure to heat or cold can cause batteries to lose their charge at a faster rate. When changing the batteries in a device that contains multiple cells, all of the batteries should be replaced at the same time. Although only one battery may be drained, mixing old with new tends to put strain on the older batteries and may cause them to leak or rupture. It is also a good idea to avoid mixing batteries from several manufacturers in a single device. In order to preserve battery life, buyers should consider removing the batteries from devices that they do not intend to use frequently.

How to Buy Batteries and Chargers on eBay

Buying batteries and chargers online is a great way to save money while maximising the selection of products. Buyers should begin their search for from eBay's home page. Buyers can easily search for " batteries " and " chargers " by using eBay's keyword search. Alternatively, a buyer can use eBay's advanced search function. This allows them to limit their search by price or condition. Buyers can also limit results to items sold by Top-rated sellers. Top-rated sellers are recognised by the eBay community for their high levels of customer service. These sellers receive consistently positive feedback ratings, which are left by previous buyers.

Buyers should always review a item's description before making a purchase. If buying batteries and chargers, the item description should include the condition of the components, as well as any relevant information, such as the brand or type of battery. If not fully satisfied with the item's description, buyers may contact sellers by using the "Ask a question" feature. Good sellers are glad to answer any questions or provide any information that the buyer may need in order to ensure a positive transaction.


Choosing the right type of batteries for a device is important. Although multiple types of batteries may work with any one device, some types are better suited than others. So, buyers should consider the type of device: if it is a high-drain device, then buyers should invest in rechargeable batteries. However, if the device uses little power, then disposable batteries may better suit their needs.

In addition to the type of batteries, buyers should also take into account the various safety tips that help them to form a well made decision. The quality of the battery and the date stamp should be inspected carefully to ensure long-lasting and safe use. Storing the batteries properly can also extend the lifespan of the batteries. Batteries should be stored at room temperature away from metal objects. Buyers should consider the type of charger and ensure that they purchase a model that does not overcharge batteries. With the wide selection of batteries and chargers available on the eBay website, buyers are sure to find the perfect power source for all of their devices.
