4 Factors to Consider when Buying Rechargeable Batteries

A wide variety of different appliances and tools require the use of batteries in order to power them, and single use batteries, while affordable and simple to use, can become costly to replace over time. For some uses, a rechargeable battery may be the best option.

Rechargeable batteries can simply be recharged once they have become flat, and can save money over time. A variety of different types of rechargeable batteries are available which can be fit into all kinds of different devices, while different chemical make ups of a battery can offer different properties. A wide range of rechargeable batteries is available on eBay.

The Device the Batteries are Needed For

Before purchasing a pack of rechargeable batteries, the device that they are to be used with should be considered. This can impact both the type and size of battery that should be purchased, as well as whether rechargeable or single use batteries are a better choice.

· Some devices, such as remote controls, may operate from the same batteries for a great deal of time. Rechargeable batteries may be less suited to this kind of device, as they are often more liable to 'self discharge' when not in use, meaning they can lose power and become flat.

· Similarly, some types of very small device use very small batteries, which are not typically available in rechargeable form. These include items like watch batteries.

· Rechargeable batteries are suitable for a wide range of applications. These batteries make a good choice for use with devices that will last a great deal of time, as they would likely go through many single use batteries, which can become costly.

· If an item is used regularly, it may be best to ensure that there are spare sets of rechargeable batteries available. This means that charged batteries can be rotated through the device, ensuring its uninterrupted use.

The Size and Design of a Battery

Both single use and rechargeable batteries are available in an enormous array of different sizes and shapes, with the size and shape needed depending on the device that requires to be powered.

· Perhaps the most commonly used sizes of battery are AA and AAA batteries. These are compatible with a wide variety of different electronic devices, large and small. Many items will require two, four or even six of these batteries in order to function. Due to the number of these that are produced, they are also among the most affordable types of battery.

· C and D size batteries are somewhat larger than the smaller AA and AAA sizes, and are also popularly used and widely available in rechargeable models. C batteries are most often necessitated for moderate drain devices, such as electronic toys and instruments, while D batteries are designed for use with high intensity devices, which may be required to run for a considerable length of time, such as radios, megaphones and larger flashlights.

· Another widely available type of rechargeable battery is the 9V battery. These batteries are larger and squarer in shape than many other types of battery, and are often used in items such as smoke detectors, RC car controllers and some types of electric guitar.

The Type of Rechargeable Battery

Batteries are made up of different types of metal, which can offer different properties to the battery.


Alkaline batteries are among the most widely available types of rechargeable battery. These batteries can be quickly and efficiently recharged, with a charge that can last a great deal of time. However, alkaline batteries are more prone to self-discharging when not in use than other types of battery.


Nickel-metal hydride batteries, generally shortened to NiMH, are among the most widely available types of rechargeable battery, and are capable of holding a comparable charge to the more expensive lithium ion battery. However, NiMH batteries will not function optimally in devices that were designed primarily for use with alkaline batteries.


Nickel-zinc, or 'NiZn', batteries are one of the more recent types of rechargeable battery to become available. These batteries offer a considerable reduced rate of self-discharge, meaning that they can be charged and left in storage for longer. NiZn batteries are also non-toxic.

Lithium Ion

Lithium ion, sometimes called 'Li-Ion' batteries are among the most expensive available. Li-Ion batteries are more commonly used in more expensive electronic devices, such as mobile phones and laptops, and are uncommon, but available, in smaller sizes. Lithium Ion batteries are, however, prone to overheating if they are of a lower quality.

Silver Oxide

Silver oxide batteries are among the most expensive and difficult to obtain types of rechargeable battery. These batteries are most commonly used in very small devices, with silver oxide batteries of larger sizes being very unusual.


Nickel-cadmium batteries are some of the most affordable types of battery. They offer a very high output without the loss of long-term capacity that this can mean for other types of battery. However, NiCad batteries are also more prone to self-discharge than other types, and can rapidly lose charge when not in use. Furthermore, this type of battery is highly toxic, and their use is heavily regulated in some countries.

The Types of Battery Charger

Rechargeable batteries can make use of a variety of different methods to recharge, and some can offer different benefits.

· The most common types of battery chargers are mains chargers. These can be plugged into any mains electricity outlet, and can often recharge multiple batteries at once.

· A more convenient option for some may be a USB charger, which can plug into a computer's USB port to take power. These may take longer to charge up batteries than mains chargers.

· It is also important to match both the size and chemical makeup of a rechargeable battery to a charger. Many chargers are specifically designed for use with certain types of battery, and may not function properly with other types. In addition, the wrong size of battery will not fit.

How to Buy Rechargeable Batteries on eBay

A wide range of rechargeable batteries of many different types and sizes, along with a variety of chargers, can be found on eBay.

· The full listing of available rechargeable batteries section can be found under the Batteries, Chargers section of Electronics, which is under Rechargeable Batteries.

· The listing of batteries can be narrowed down by a number of categories in order to make the process of finding the right battery easier. These include price, as well as the size or brand of a battery.

· Important information about a particular item, such as the type of battery, is often prominently displayed in the item listing, making it easy to quickly see if an item meets any requirements.

· Further information can be found on the item page, including information about the seller, such as item reviews and feedback ratings, which helps to ensure that a purchase can be made with confidence.

· If a particular type of battery is required, it may be easier and faster to use the search bar, which can be found, at the top of every page. Searches can be made to return results from within a specified category, or from across the site.

· Don't forget to look out for deals on batteries, which may be available under the Electronics category.


Batteries are highly useful items that are required to power all kinds of electronic devices, including flashlights, toys, radios and smoke detectors. Maintaining a supply of batteries can be a good way to ensure that these items can always be used.

Rechargeable batteries offer a more affordable way of powering some of these items, as they can be re-used repeatedly. A wide variety of batteries, both rechargeable and single use, along with different types of charger, can all be found on eBay.
