How We Decided Battery chargers aren’t few and far between by any means, and it can be almost overwhelming when faced with so many different options. So, to narrow down the list for you, we focused on battery chargers that were versatile and extra safe to use. We tested each battery charger on a variety of different battery types, including car batteries and recreational vehicle batteries. We also looked for battery charges that are easy to use. The best battery chargers feature either full displays or indicator lights that give you a quick idea to know exactly what’s going on with the battery and its charge. They should also be able to switch between different modes or power outputs so you can easily tailor the charge to your specific situation. Finally, we looked for battery chargers that are durable and long-lasting. It’s likely that you’ll be moving the charger around a lot to different places in the garage or under the hood or stored somewhere in a drawer. As such, you’ll want to be sure you have an option that won’t break with every bump that may happen. Battery Charger Buying Guide The Most Important Features to Consider Total Power Most battery chargers draw power from a 12V battery built in to the charger, but the power going to your vehicle’s battery is measured in amps. The higher the amperage, the better and longer lasting the charge will be. Chargers with higher amperage also tend to charge your batteries faster. However, the more power you get for your charger, the more expensive the product becomes, so keep that in mind as you’re shopping around. Safety Dealing with high levels of charge going into your batteries always carries an element of hazard, so you’ll want to be sure you purchase a charger that offers built in safety features. Fortunately, most modern-day battery chargers provide such features. We recommend looking for an option that has at least one, but preferably more of the following features: Reverse polarity protection Spark proof design Auto voltage detection Automatic charging capabilities Multi-stage charging User Friendliness We recognize that not every customer purchasing a battery charger is an experienced car mechanic or even mechanically inclined, so we’ve only included battery chargers that are easy to use. Chargers that offer a high level of user friendliness include features that specifically make your life easier. Features like quick connectors and LED status indicators or full displays all make the experience much easier for you and build your confidence that you’re using the device correctly. Portability If there’s one thing to remember about batteries, it’s that they never lose their charge in a convenient place. You should always plan for the worst when it comes to needing to charge your battery, which is why it’s so important that you purchase a portable battery charger. Look for chargers under 5 pounds that also have convenient carrying handles or storage bags for easier transport.
