Car Battery Charger – How to Pick

Before you buy a charger for your automobile batteries you have to consider the type of battery that you have on your automobile and the size of your battery. When we talk about the size we are referring to the number of amp hours your battery is designed to have.

Batteries can be:

  • WET which is maintenance free batteries. You never have to add water or check the fluid levels in this type of battery. These are an older battery version and they are generally the cheapest type of automobile battery because they do not last as long as the other types.
  • AGM which are batteries absorbed glass batteries. They have a specialized material in place that moves the battery electrolytes from one battery plate to another. They only contain a small amount of liquid in them, and if you are in an accident and the battery is broken fluid or battery acid will not leak from the unit. These batteries can take a charge about five times faster than the average WET battery can. They also stand up to cold temperatures better than the WET or maintenance free batteries do. They can hold their charge when the temperature starts to plummet where often freezing temperatures will drain the power from a WET or maintenance free battery.
  • GEL which is valve regulated lead-acid batteries. This type of battery is also sometimes referred to as a VRLA. One of the drawbacks of the WET batteries is they have to be kept in an upright position. If they are tipped over the fluid can leak from their cells and the battery can be permanently damaged. The GEL cell batteries do not have liquid in them, they contain a mixture of sulfuric acid that is combined with a fumed silica that creates a gelled electrolyte that stays in place and will not leak out if the battery is not kept in an upright position.

Once you know what type of battery you will be charging buy a charger that is designed for a battery of that size. The common car battery will maintain for about 50 amp hours. Battery chargers come in different amps and if you buy a battery charger that is a 10 amp charger it will charge your 50 amp battery, but it will take about 6 hours to do the job. If you try to charge something like a marine battery with a 100 amp capacity it is going to take a little 10 amp charger about 11 or 12 hours to do the job.

If you are buying a charger to keep your battery on a boat, or motorcycle at top charge while then you can buy a smaller charger.

Safety Features

Safety has to be a major concern for us when we are considering a charging system for our automobile. You want a charger that will not injure you or the battery you connect to it. The following features are common on battery chargers, and you should try to buy a charger that has as many of these features as possible.

  • Fully automatic chargers are safest for the battery you will be charging. These systems can sense when the battery has a complete charge and they will not allow the battery to be overcharged. They extend the life of your battery.
  • Reverse polarity prevention. If you connect the wrong cable to the wrong terminal on a battery it can cause dangerous sparks and can possibly cause the battery to explode, or at the very least be damaged. A great safety feature is when the battery charger alerts you to the fact that you have the wrong cable connected to the wrong terminal.
  • Float mode is when the battery charger keeps the battery at a full charge but does not allow the battery to be overcharged. This is a great feature because you can connect the charger and then if you do not go unhook it when the battery is precisely charged you will not damage your battery.
  • Spark proof clamps will prevent dangerous sparks from occurring under your hood if your clamps touch each other. You can call this fire prevention.
  • Some chargers can detect when a battery is not going to be able to hold a full charge because of a sulfate buildup on their plates. This happens often with lead-acid batteries. The chargers sense the problem and can alert you so you can remove the buildup or some of the chargers will attempt to correct the problem for you.

Car Battery Chargers VS Jump Starter

There are both car battery chargers and machines called jump starters available. A jump starter is designed to provide extra cranking amps to your battery in a short time, and a car battery charger is designed to charge your battery so it is at its maximum cranking potential. The following comparison should help you determine whether you need a charger or a jump starter.

Car Battery Charger

    • Can provide full cranking power that can last the number of amp hours your battery is designed to provide
    • They are usually used while you are at home, or while the battery is going to be in one place for an extended period of time
    • Maybe more expensive than a jump starter
    • Usually, have more safety features than jump starters have
  • Maybe larger and bulkier than the jump starters are

Jump Starter

    • Gives instant cranking power that will last about ten to fifteen minutes. These generally are used in emergency situations to provide you enough power to get to a mechanic for advice on why your battery went dead.
    • They are usually smaller than the average battery charger
  • Jump starters are temporary sources of power while chargers provide long-term power

So you should buy a car charger to help you maintain the life of your car battery and you should buy a jump starter to help you provide extra power to a battery in a crisis situation. It is advisable that you have both of these items on hand so you are protected from emergency situations and so you have the ability to do maintenance charging on batteries that may have grown weak, or batteries that may sit for long periods of time between use

Summary

The best car charger is a device that can maintain the power capacity of any battery that you have. That means they would work for charging the battery on your automobile, your lawn equipment, your watercraft like your jet skis, your snowmobiles, your ATV’s, your fishing boat, and more. You do not want to have to buy a charger for each different type of motorized device you own. You want one that is fully automatic and one that will alert you to system problems like alternators that are not functioning at full capacity.

The best charger for your purposes is one that has the power you need, the safety features you desire and is in a price range that you can afford. Comparison shopping will allow you to find a charging system that fi9ts all of these categories.
