How to Buy Batteries and Chargers on eBay

The first battery ever invented was credited to Italian physicist Alessandro Volta who designed it in 1800. Inconsistent in voltage, and unable to provide power output for long periods of time, the initial batteries was sub-par at best. They were delicate and bulky, and was not portable. In modern times, batteries can be as small as a fingernail and can last for years if treated correctly. While disposable batteries are still useful in some situations, batteries which are rechargeable are popular and necessary in a variety of modern devices from mobile phones to surveillance equipment.

Each kind of rechargeable battery requires a special battery charger, from the common rechargeable AA battery to a mobile phone and laptop battery. Moreover, chargers use different methods to charge batteries in order to extend the lives of the batteries. Those looking for a battery charger should be informed about the different kinds of chargers made today so that they can purchase the type of charger best suited to their needs.

Disposable Batteries

The first mass-produced batteries were designed with a certain charge and lifespan, and when those thresholds were reached, the batteries was discarded. Battery recycling centres are few and far between. These types of batteries are still in use and are known as primary or disposable batteries.

They are designed to be used in portable devices that do not require larger amounts of current or those which are used in a sparing fashion. These batteries do not have chemical reactions that are easily reversible and so cannot be returned to their original form. Thus primary, or disposable, batteries cannot be recharged. When purchasing disposable batteries on eBay, be sure to ask the seller if the product was previously used, and how vigorously since the potency of these batteries diminish over time.

Rechargeable Batteries

Secondary batteries are also known as rechargeable batteries, and they can have their chemical reactions reversed via the introduction of electrical charges after their energy is spent. Secondary batteries are widely used today in many different types of technological equipment that draw large sums of energy from the batteries.

The ability to recharge secondary batteries dramatically reduces the cost associated with having to constantly replace primary batteries when these electronic devices drain them. While primary batteries are still very useful and found in many different applications, secondary batteries have become very popular and commonly used items that people depend on daily. There are many different types of rechargeable batteries, and each type uses a different battery charger to keep them functional.

Battery Chargers by Method

There have been several different types of battery chargers developed since secondary batteries became a part of everyday life. Few devices are sold without an accompanying battery charger, showing the importance of such devices. Consumers are wise to learn about the kinds of chargers, categorised by the method they use to charge batteries. Most any battery charger is available on eBay. Consumers should be sure that the part of the charger that connects to the wall outlet matches the country they live in.

Simple Battery Chargers

A simple battery charger works by supplying a constant electrical current to the battery being charged. Unlike many other chargers, the simple charger does not alter its output by time or amount of charge. It simply charges at a constant level regardless of the charge state of the battery. Since it does not have a shut-off capability, the simple charger generates a low-to-moderate charge in order to prevent severe over charging. The simple charger is easy to use and inexpensive to produce, making it a commonly used device to charge secondary batteries.

Fast Chargers

The fast battery charger is capable of rapidly charging a depleted battery without damaging its internal circuitry. The fast battery charger manipulates the internal characteristics of the battery in order to force a much quicker charge upon it without overheating the battery in the process.

Smart Chargers

The smart battery charger can monitor the condition of the battery it is charging and modify its charge output accordingly. A smart battery charger utilises a few different kinds of technology to read the battery's state. Some smart chargers monitor battery temperature or time on charge, while others monitor actual voltage level of the batteries. Smart chargers employ shut-off systems that act as safety valves and prevent the chargers from overcharging batteries.

The smart charger is an important step up from the simple charger in that it gives the user freedom from monitoring the condition of the battery or the time of the charge. Smart chargers are more complicated and thus more expensive than simple chargers, but to many users, the additional expense is worth it.

Trickle Chargers

The trickle battery charger is a charger that uses low current over a longer period of time in order to charge the battery. Trickle battery chargers generally are used on lower capacity batteries that do not require larger currents to charge. Trickle battery chargers are also used for slow charging or "topping off" larger batteries such as those in cars, recreational vehicles, and boats.

Trickle chargers maintain the level of these larger batteries indefinitely. Since trickle chargers produce such low current levels, they do not have the capability of overcharging the batteries, so they can be left on the batteries to charge indefinitely. This is a valuable aspect of trickle charges which makes them attractive to boat owners and people who live in colder climates where vehicle batteries can be drained by inclement weather. Trickle chargers are common and easy to recharge and they are relatively inexpensive to purchase.

Solar Battery Chargers

The solar battery charger effectively uses sunlight to slowly charge many different types of batteries. Solar battery chargers are a very convenient option because they do not require AC power in order to charge the batteries. Although solar battery charges depend on the sunlight, they are effective in cloudy conditions as well. Solar battery chargers operate like trickle chargers in that they provide a slow and steady charging current.

Unlike trickle chargers, however, solar chargers are capable of fully charging depleted batteries as well as maintaining their levels. Solar chargers can be used on any type of rechargeable battery and are generally inexpensive despite the level of technology they utilise. Before purchasing a solar battery charger on eBay, ask the seller how much it has been used, and if the solar plates have been bent, as that can damage the effectiveness of the charger.

Types of Chargers by Battery Type

Apart from the charging method used by the charger, the most important characteristic of a charger is its compatibility with the battery in question. There are a multitude of batteries available to the consumers and they come in many different shapes, sizes, voltages, and uses. There are nearly as many variations on the design of the battery charger as there are batteries, and regardless of the size or requirements of the battery, there is a charger built for it. Before purchasing chargers on eBay, consumers should be aware of the type of batteries and the size of the batteries since not all chargers fit all battery varieties.

Standard Battery Chargers

Standard battery chargers are the most common and inexpensive chargers available on the market. They are used to recharge smaller rechargeable batteries that power many of the everyday items that are constantly used. There are several different materials used to make up standard rechargeable batteries including Li-ion, NiMH, and NiCd. Each of these types of batteries may be recharged time and time again, making them a very cost-effective alternative to standard alkaline primary batteries. As technology increases, the abundance of inexpensive battery chargers on eBay increases.

Mobile, Electronics, and Camera Chargers

Batteries used in mobiles, cameras, and other various types of electronics are all rechargeable and require specific types of chargers to recharge them. Camera batteries are very seldom the same size or shape and each one usually requires a battery charger specifically designed for it. Mobiles and laptops differ in that their batteries usually remain in the device during charging. Manymobiles use USB chargers.. When searching for a mobile, electronics, or camera charger on eBay be sure to specify the type of battery needed to charge by clicking on the relevant categories.

Vehicle Battery Chargers

Vehicle battery chargers come in many different sizes and have different uses and capacities. Some types of vehicle charges are compact units no bigger than a shoebox and can be used to trickle charge vehicle batteries. Other units are very large and are used to fast charge vehicle batteries which have been run down because of interior lights or other draws on the system. These chargers usually also have a jump start feature that allows vehicles with dead batteries to be started without having to charge the batteries first.
