The Benefits of Buying Charger & Battery Combos

Charger and battery combos have a range of benefits, including saving money. There are many different types of rechargeable battery available, so buying them combined with a charger ensures that the items are fully compatible because not all rechargeable batteries work with all chargers. The charger bundled with the battery has the appropriate power levels, so it charges the battery fully and safely. This helps to maximise the lifespan of the battery. The battery also fits correctly in the charger. Rechargeable batteries and charger combos are more environmentally friendly than using disposable batteries.

To understand the benefits of buying charger and battery combos, it is helpful to know the types of rechargeable batteries and chargers available. The main type of rechargeable battery are nickel cadmium, nickel metal hydride, lithium-ion, and rechargeable alkaline. Charger and battery combos can be bought at supermarkets and electronics shops. eBay offers charger and battery combos for every battery size and type.

Types of Rechargeable Battery

Rechargeable batteries are available in an array of sizes and can have different chemical compositions. Each composition has different properties and lifespans.

Nickel Cadmium Rechargeable Batteries

Nickel cadmium rechargeable batteries were the first buyer-grade rechargeable battery. They are available in both button and cylindrical sizes, suited to a wide range of common household items. They are durable and robust, performing well in very low temperatures. They are also resistant to overcharging. Nickel cadmium batteries contain highly toxic substances, so they should be handled with extreme care and disposed of safely, especially if they begin to leak. They are also prone to a shortened lifespan if they are not fully discharged before being placed in the charger. Nickel cadmium batteries can usually be charged between 300 and 700 times before they need to be replaced.

Nickel Metal Hydride Rechargeable Batteries

Nickel metal hydride rechargeable batteries should be recycled or disposed of with care, even though their contents is less toxic than nickel cadmium. Nickel metal hydride batteries have a considerably higher energy density, making them suited to high drain devices. Each charge lasts for much longer than nickel cadmium batteries. Nickel metal hydride batteries do not require a complete discharge before charging, but do not hold their charge well when left unused. They are available across all battery types, including common household cylinders and button varieties. Nickel metal hydride batteries can usually be charged between 300 and 600 times before they need to be replaced.

Lithium-Ion Rechargeable Batteries

Lithium-ion rechargeable batteries have a very high energy density and are able to provide a long charge to even the highest drain devices, such as digital cameras and laptops. Lithium-ion batteries also hold their charge well between uses and have a very slow self discharge rate. They have a complex chemical composition that is very volatile. This means that it is wise to use these batteries only in devices with protected circuitry. Lithium-ion batteries do not need to be fully discharged before being charged and they can be charged in excess of 1,000 times before needing replacement.

Rechargeable Alkaline Batteries

Rechargeable alkaline batteries are inexpensive and well suited to low-drain devices, such as alarm clocks and remote controls. They have a low energy density, meaning they are not best used in high-drain devices. Rechargeable alkaline batteries hold their charge well and self discharge very slowly. Rechargeable alkaline batteries can usually be charged up to 400 times before they need to be replaced.

Advantages and Disadvantages of Rechargeable Batteries

The table below presents the advantages and disadvantages of each type of rechargeable battery. Using this table, buyers can decide which type of battery best suits their lifestyle and the devices that require power.

The table above allows buyers to select the best rechargeable battery for their devices. It provides a quick reference to the advantages and disadvantages of each type of rechargeable battery.

Types of Battery Charger

There are two distinct types of battery charger: time controlled and smart. While each charger is used to provide a charge to rechargeable batteries, they have different properties. The type of battery charger that accompanies the batteries in the combo set is certain to be a good match for the type of batteries provided.

Time-Controlled Battery Chargers

Time-controlled battery chargers have a predefined charging time. The timer switches off the power to the batteries after this time. The times range from 4 hours to 27 hours depending on the type of battery. Time controlled battery chargers are the least expensive option. If incompatible batteries that require a different charging length are used, then they will either be overcharged, which causes significant damage to the batteries, or under charged, providing a limited amount of power and wasting a charging cycle.

Smart Battery Chargers

Smart battery chargers are also known as intelligent chargers. These chargers can detect the amount of charge left in a battery cell, regardless of the battery type. Instead of using a timer, smart battery chargers charge the batteries based on how much energy is currently in the cell. Smart chargers cut the power when the battery is 100 percent charged to ensure that there is no overcharging, which can damage the battery. They also ensure that undercharging does not occur, which maximises each charging cycle. Smart battery chargers are more expensive than time controlled models.

Benefits of Charger and Battery Combos

There are a number benefits to buying charger and battery combos, including the compatibility of the items, the money saving opportunities, and the environmental benefits of an increased lifespan of the batteries. Before buying charger and battery combos, buyers should consider the types of batteries that they require.

Compatibility of a Charger and Battery Combo

Buying a charger and battery combo ensures that the batteries are fully compatible with the charger. Some rechargeable batteries require a very specific charger, so buying a combo set ensures that the batteries fit correctly and securely into the charger. This is a valuable benefit, as it means that a proper connection is maintained. A solid, secure connection is required for the batteries to receive a full charge and limits any breaks in the cycle that may cause a shortened lifespan.

Money and Time-Saving Benefits of a Charger and Battery Combo

Purchasing charger and battery combos enables the buyer to save money. When bought together, chargers and rechargeable batteries typically cost much less than when purchased separately. Also, because the batteries are fully compatible with the charger, buyers can get the maximum value for money by extending the lifespan to its full capacity.

Environmental Benefits of a Charger and Battery Combo

Rechargeable batteries are far more environmentally friendly than disposable batteries. They can be recharged hundreds of times, so there are far fewer batteries sent to landfill. Buying charger and battery combos further helps the environment, because the charger and batteries are fully compatible, which maximises their performance and lifespan, thereby reducing the frequency with which batteries need to be replaced. So, buying rechargeable batteries saves money and helps the environment.

Buying Charger and Battery Combos on eBay

Buying charger and battery combos on eBay provides money saving options. Charger and battery combos can be found by searching from the eBay homepage using a phrase like " charger and battery combos &", or by navigating to the most relevant category. Specific information about the size or chemical composition of the batteries can be included in the initial search to reduce the number of results.

Buyers should read the item listing carefully to ensure that the batteries in the combo set are the right size and type. Buyers can also contact the seller to request any additional information. Most sellers respond promptly to information requests and are happy to assist a buyer with anything relating to their product.

Feedback is an important aspect of the eBay buying process. Buyers should check the feedback score of a seller before they commit to buying their desired charger and battery combo. Feedback is composed of opinions left by other buyers after their own transaction with the seller, and so provides information on service, product quality, and efficiency of delivery.


One of the benefits of buying charger and battery combos is that it ensures that the correct charger is purchased for the type of battery. This maximises the lifespan and longevity of the batteries. Charger and battery combos also save the buyer money in a number of different ways. Buying one combo set is usually less expensive than purchasing the items individually. In addition, as the charger and batteries are matched perfectly, the maximum performance and lifespan of the batteries are achieved, reducing the frequency with which the batteries need to be replaced. Buyers should also consider what type of battery charger they want. The two options are a time controlled or smart charger.

Rechargeable batteries are available in a number of chemical compositions with different properties, ranging from inexpensive, short charge alkaline batteries, to more expensive, high-energy, long-life lithium-ion batteries. With the number of benefits of buying charger and battery combos, buyers can purchase the items on eBay with confidence.
