Best 12 V Battery Chargers - Buyer's Guide
The rule of thumb when buying 12 V battery chargers is the first thing you should look into is the output current. The higher the output current, the higher the charging power of the charger. If you would like to revive the battery of larger vehicles that have been long-dormant for many years, consider purchasing a battery charger with a higher output current. But if you plan on using your charger for emergency purposes only, you can utilize a lower amp.
Most 12 V battery chargers are used to either maintain batteries or revive long-dormant automobile batteries. If your purpose is to maintain batteries, you can consider a more heavy-duty battery charger that is bigger in size and heavier in weight, provided that you will store it in your garage. If you are planning to use this more of an emergency tool and plan to store it in your car, consider purchasing a more portable and lightweight battery charger.
For automotive newbies, using a battery charger can be rattling and confusing during emergencies. When looking for a battery charger, go for the plug and play ones where you have to plug in the cable, and it will automatically charge your car.
Have you heard of horror stories or reviews where owners go and plug their batteries, leave it for a few hours, and come back with the top of the hood exploded in their garage? If you don’t want this to happen to you, search for the safety features, including floating status, battery indicators, and guarded plugs.
You have to ensure that you get value for your money. Check on the different items included when you buy a battery charger. For example, ask yourself what cords are included? What connectors come with the tool? The added cables and connectors will save you money in the long run.

Typically, most 12 V battery chargers have LED charger indicators that tell you whether your battery is fully charged. If your charger does not have this feature, you can use a voltmeter to check if your battery is fully charged. Ensure that the voltage is geared towards 12 V, which means that your battery is fully charged.
