Car Battery Charger Buying Guide

In order to restore power to a dead battery, you will require a car battery charger. They are available in a variety of different power ratings that range from as little as 0.75 amps to as big as 26 amps.

Along with the choice of different amperage ratings, there are also a range of types that include a standard, trickle or smart car battery charger. Regardless of the model you choose, by owning a charger, you will always be able to restore power to a dead battery.

To help you make an informed buying decision, we have produced the below guide regarding car battery chargers.

Different Types of Chargers

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

Standard/Basic

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

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 the battery in order to maintain its optimum power. This type of charger is perfect for those that have cars 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’s “smart”. In short, it’s a combination of both the standard and trickle charger types but extra features can 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 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.

As stated by NOCO, you calculate the time it takes to charge a battery by multiplying the battery amperage per hour by the depth of discharge. This provides you with the total number of hours required to achieve maximum charge.

In short, 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 of charging batteries. You can either leave the battery installed without any load or alternatively remove the battery to charge it 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, it’s 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 placing it indoors is the safest option and it can sometimes easier. For example, not all battery chargers are waterproof and you may not be able to run an extension cable to your car.

When you come to installing the battery back into the car, we advise double checking it’s placed back correctly. This means checking the terminals are next to the matching positive or negative and that it’s 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’s 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. Therefore, spending slightly more for a charger that’s compatible with additional 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 isn’t advised and it can potentially cause damage to both the battery and the cars electronics. Fully recharging your battery to its optimum condition is the best and safest option.

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