Car Battery Charger Buyer’s Guide 

The right equipment is essential when it comes to charging a vehicle’s battery. There are lots of options available, each one suited to varying battery sizes, types and situations. It’s important the chosen battery charger not only works with your vehicle but also has the features you require. This guide will help you find the best car battery charger for your needs. 

Types of Battery Chargers 

There are three types of car battery chargers to consider. Most are able to charge, maintain or restore and a few are able to do all three. If you need a charger that is going to do all three you can expect to pay a considerably higher price for the convenience and abundance of features. 

1. Standard Charger 

A standard battery charger is a popular and low-cost option. As you would expect of a charger, this type basically gives power to your car’s battery. If a battery is completely discharged a standard charger may be able to restore it but they are mostly used for simply charging batteries.

2. Battery Maintainer 

A charge maintainer is used to stop a battery from completely discharging. This can help maintain the car battery’s overall health. Using a battery maintainer is not as popular as the other types but it can make charging car batteries easier. 

3. Restorer

If you are working with old batteries you may want to consider buying a full battery restorer. This breaks down contaminants in the battery cell to help restore and bring new life into the battery. As they are restoring totally flat or old batteries they do tend to cost more than the other types but they are worth the extra cost. 

Features To Look Out For 

  • Charge Life – Before you buy a car battery charger take a look at the charge life and how long the recharge time is. The best way to look at charge life is how many full car battery charges you can get out of the fully charged device.
  • Power – Take a look at the amperage and voltage offered by the charger. Check this against the amps and volts needed to charge your battery.
  • Time – How long will the charger take to fully charge a battery? When you charge a car battery it can take hours depending on the voltage and amperage so be sure to take this into consideration when choosing a new charger.
  • Indicator Lights – LED lights are a useful feature that let you know what is going on. These lights will let you know if the charger is on, holding or receiving charge. 
  • Budget – There is a lot of variation in the price of battery charges. A standard charger is going to cost less than a restorer so take into account what you need the charger to do and what your budget is. You will pay more if the device has a lot of features so you will be able to save money by buying one that has only the features you will use.
