A battery charger is a device designed to push electrical energy through a secondary cell or a battery to recharge it. Different types of rechargeable batteries respond best to different types of charging; therefore it is important to know which charger or chargers are applicable for the different batteries that you need to recharge. For example, a mobile phone should not be charged with a car battery charger, neither should a NiCd charger be used to charge NiMH batteries.

### **How do battery chargers work?**

A typical rechargeable battery can be charged many times. Firstly, it is important to be sure that the battery in question is indeed the type that allows for recharging. If it is rechargeable, it can be connected to the charger unit. Once the current start to flow, the electrodes that have depleted out of the batteries are recharged and the battery's energy is restored. It is important to cut off charging once maximum capacity is reached, or the batteries will have to expend excess energy and will overheat, leading to risk of rupture, chemical leaks, or sometimes even the explosion of the battery.

### **What are the different methods of battery charging?**

As there are different chemical contents in different batteries, there are different methods of battery charging that are the most suitable for each chemistry and battery type. There are battery chargers available for standard sizes, including AA, AAA, C, D, and 9V, and there are also battery chargers available for larger lead-acid batteries. Some battery chargers have slots for the smaller cells to be placed into for charging and these often fit straight into a plug socket for power. Other battery chargers come with crocodile clip connectors to connect to larger, lead-acid batteries.Lead- and lithium-based chargers operate on constant current constant voltage (CC/CV).Nickel-based batteries charge with constant current and the voltage is allowed to rise freely.

### **Types of battery chargers:**
- Lead Acid Battery Chargers
- Car Battery Chargers
- AAA and AA Battery chargers
- 12V and 24V Battery chargers
- Lithium Battery chargers

### **Features and Benefits**
- Cost effective - by recharging batteries, they can be reused multiple times before being disposed. Recharging allows for a battery's performance life to be expanded and prevents them from being sent to landfill
- Eco-friendly - recharging a battery is better for the environment as recharging batteries reduces the number going to landfill as well as reducing the need for more batteries to be produced
- Suitability - there are several types and models of battery chargers that can be used to charge several chemistries including lithium-ion, NiCd, NiMH
- Adaptability - some battery chargers will work in your car if they have an adapter, providing charging on the move for professional and personal gadgets such as cameras, monitoring equipment, and more
- Visual completion - lights that change colour to provide a visual indication of charging completion

Lead Acid Battery Charger | RS

Lead-acid battery chargers charge lead-acid batteries in a effective way that can provide smaller batteries ready to use in 5 hours and larger as quick as 12 hours. Lead-acid batteries utilise a method of charging called 'constant current constant voltage' This process uses a regulated current. That current works to raise the terminal voltage within the battery until the limit of the upper charge voltage is met.Tips for using a lead-acid battery charger:Only operate charging in a dry, ventilated area.Do not over-charge: Keeping the battery on the charger for too long.Do not under-charge: Removing the battery before it has time to fully charge.Ensure you check fluid levels

Automotive Battery Chargers| RS

An automotive battery charger is very similar to a mobile phone or laptop charger, plugging into an electrical outlet at one end and connect to the car battery terminals with cables such as jumper/ boost cables. Like a mobile phone charger, car battery chargers deliver a consistent flow of power, allowing it to recharge or maintain the charge of a vehicles battery and discharging when completeCar batteries require 12-volt DC type current to charge and electrical outlets put out 120-vol AC type current. Battery chargers convert the 120-volt AC current drawn from an electrical outlet to a 12-volt DC outlet.Car battery chargers come in a variety of amp-hour (Ah) ratings, which mirrors their strength and how quickly they can charge a battery. Amp rating often range from as little as 0.75 Amp to over 100 Amp.A car battery typically has 48-amp hour rating while smaller vehicles like motorcycles, jet skis, and snowmobile have 20 Ah or lower.<h3>When To Use Car Battery Charger</h3>A car battery charger is ideal to maintain a car&rsquo;s battery charge on a vehicle that is not used regularly or for a vehicle with a fragile battery, for example. If the vehicle battery is consistently failing and discharged, it is expected the battery would need replacing.Often as car battery chargers normally take numerous hours to charge a battery, they are not ideal for emergency or time crucial situation, for example a car not starting before a journey. This is typically due to cold weather or the battery being drained by a feature of the veichle being left on overnight or prolonged periods.
