Different Types of Chargers

Battery chargers have seen an enormous amount of improvement over the years. Manufacturers have been competing to produce the best, which has resulted in various different types being available. The main types include the standard charger, maintainer and the desirable smart battery charger.

Standard/Basic

These will be the cheapest and simply charge a battery at a fixed rate until it is fully charged. Not every charger will automatic switch, which may result in overcharging. This can be damaging to the battery and is why you must monitor the charging process.

Maintainer/Trickle Charger

The purpose of a maintenance charger is to keep the battery topped up without overcharging or causing any damage. They are designed to provide low current to help the battery maintain its perfect amount of power. This type of charger is perfect for those that have cars that they drive on the weekends or when it’s occasionally sunny in the UK.

Smart Car Battery Charger

By far the best type of car battery charger is one that is “smart”. In short, it is a combination of both the standard and maintenance types but extra features, which include:

  • Additional safety functionality
  • Diagnostic tests
  • Battery repair modes
  • LED display
  • Various modes
  • … and much more

If you are able to stretch your budget, we would highly recommend opting for a smart battery charger.

Amperage Rating

Many of the big brands will provide various amperage ratings with their chargers. Depending upon the battery size will determine the length of time it takes for a charger to restore lost power. Therefore if you were to have a charger with a high amperage rating, it will be able to charge the battery far quicker.

You can calculate the length of time it would take to restore power to a dead battery. As stated by NOCO, you can multiple the battery amperage per hour by the depth of discharge. This will provide you with the total number of hours to maximum charge.

If you require fast charging, you should choose a car battery charger with a high amperage rating.

Cables and Clips

Battery chargers need to be able to withstand tough conditions and heavy usage. To ensure that the device you choose is long lasting, you will want to ensure that the cables and clips are constructed of high quality materials. Thick copper leads and insulated battery clips are sign of superior build quality.

How To Charge a Car Battery

In terms of using a car battery charger, there are two methods. You can either leave the battery installed without any load or alternatively remove the battery to charge indoors.

Battery Left in the Car

Removing the battery in some cars can involve quite a lot of effort. Therefore leaving it installed may be the best option. Before you connect the charger, its important that you ensure all electrical loads are switched off. To ensure that this is the case, you will want to remove both the negative and positive cable from the terminals

Some vehicles may suffer electrical malfunctions if you connect the charger with the battery under load. Although it may be safe to do so, we always recommend removing the cables from the terminals for peace of mind.

Removing the Battery

Taking the battery out of the car and installing in doors is the safest option and in some case easier. Not all battery chargers may be waterproof and you will not be required to run an extension cable to your car.

When you come to installing the battery back into the car, we advise double checking its placed back correctly. This means checking the terminals are next to the matching positive or negative and that it is secured within the battery tray. The RAC have a great guide if you need assistance.

Compatibility

Almost all car battery chargers are compatible with lead acid batteries. However, not every charger will be compatible with lithium-ion, AGM, gel or wet cell battery types. Therefore it is crucial that you double check the battery you have installed in your car to avoid disappointment.

Many chargers may also work with other types of batteries that are used for lawn mowers, caravans and marine applications. Spending slightly more for a charger that is compatible with as many battery types can be very beneficial.

Conclusion

Without having access to a car battery charger, you can be left literally stranded with a dead battery. Regularly jump starting your car is not advised and can potentially cause damage to both the battery and the cars electronics. Fully recharging your battery to its optimum condition is the best and safe option.

All of our recommendations are suitable for a range of budgets and cover all the different types available on the market. Although it may not be something you use all the time, it is certainly a device that can save you a lot of time and hassle.
