Did you know: Car chargers work by supplying a constant (or pulsed) source of DC power that takes the pressure off the battery to supply it's own power.

What Are Battery Chargers For Your Car?

When looking for a battery charger or jump starter, you are going to want to look at all the features that each specific model can perform. 

You are going to have a wide variety of options; everything thing from large work-station battery rigs with different charging modes to small handheld units that plug into the wall and provide a small amount of amperage. 

If you want to stay away from dead battery problems, then you will purchase a battery jump starter unit that you can keep in the car with you at all times for supplying battery voltage the battery anytime, anywhere.

Even if your battery doesn't need to be jumped, you will be the hero if someone is stranded in the parking lot with a dead battery that needs to be jumped.

There are also smart battery maintainers that allow you to store your battery and keep it effectively charged in float mode without overcharging the battery.

What Are The Different Types of Chargers For Your Car Battery?

Small battery maintainer

Or maybe you want a slick little cable box like a battery maintainer that has ring terminals and sits on your workbench to keep your ATVs or Harley Davidson battery in top shape 100% of the time.

Full-sized/multiple terminals for a professional setting

You might even want a big heavy-duty battery charger that you have to unplug after using for a fast and strong charge and has big strong alligator clips for fast charging and also different stage charging.

Battery Jump-Starter

So your car battery dies in the middle of nowhere, and you have jumper cables. Great, who is around to give your battery a jump so you can keep driving? Nobody. And that's okay!

That's why there are battery jump-start packs that you can purchase to store in your vehicle for an extra jump in those unfortunate times when you leave a dome light on or listen to the radio too long with the engine stopped.

There are hundreds of different products on websites like Amazon that will get the job done when you need a jump start or battery charged.

A jump starter differs from a battery charger because it has the potential to deliver more amps, and can be in the form of a battery for portability.

A battery maintainer or charger puts out significantly fewer amps and can be found at a lower price. There are even smart chargers on the market that know exactly when your battery is charged and cuts power for overcharge protection.

When choosing a battery charging unit, it all depends on what you want. You can start by searching for the best car battery charger reviews online and go from there.

How Does A  Battery Charger For Your Car  Work?

Chargers and jump starters provide electricity to the battery in different amounts. 

A battery charger plugs into the wall, and then onto the terminals of the battery with either alligator clips or ring terminals. 

Each charger has a different layout of charging variations and cycles. The more expensive chargers will have amperage and voltage selections.

What all of these products have in common is that they provide power to your battery's terminals in some form or other.

Trickle chargers or battery maintainers are usually less inexpensive because they plug into the wall and only provide a small amount of amperage to slowly charge the battery or keep it good during the wintertime. 

The battery charger's function also depends on which one you buy.

Tip: Unplug your battery charger after 24 hours to avoid overcharging your battery.

What To Look For In The Best Battery Charger For Your Car?

It all depends on what you are trying to accomplish with your battery charger. You are the best judge of what you need. Having a little bit of knowledge also helps. Here are some things to look for in your next battery charging device:

Jump Start Capability

For example, maybe you need a portable device to carry around in the car with you that has an internal battery strong enough to jump-start your car battery with an air compressor built-in that will pump up a flat tire for you.

Getting your engine started after a battery failure is an easy task with a jump starter pack, and comes in clutch to get you where you need to go when your car's battery has failed.

Charging Options

Different amperage and voltage settings come in handy when charging a battery. For instance, the Schumacher SC1325 6/12V fully automatic engine starter and battery charger has a 250A engine start mode for immediate starting, a 40A rate for boosting quick energy into the battery, and 6/2A charging for maintaining a battery.

  • 250A engine start for immediate starts
  • 40A Boost rate for a quick energy boost.
  • 6/2A charging and maintaining batteries

How much time are you looking to spend charging? 

When purchasing auto parts and accessories, it's best to make an educated purchase. For example, car battery chargers that are made in the USA or closest to your location are going to be the best option for quality and price.

Having said that, a lot of American companies have outsourced their products to be manufactured in China, so it's hard to tell where exactly the product is made.

What Is the Best Battery Charger For An ATV/Motorcycle?

The best battery tenders are small, and could even be stored inside the seat or storage compartments of your motorcycle or ATV. Manufacturers like CTEK and NocoGenius make great solutions for your battery problems. 

Offroad vehicles can require quite a bit of power to start, and often are equipped with a small battery that doesn't do the job, and for this reason, it's a good idea to have a battery maintainer on hand to keep things charged and running. 

What Is The Best Battery Charger For Garage/Workshop Use?

There is a big difference between a heavy-duty charging unit that you roll around in the garage, and a small battery maintainer or jump starter that you can easily carry around in the car with you.

What Size Engine Are You Powering?

If you own a larger vehicle like a pickup truck or semi-truck, then you are going to want to make sure that the jump starter you choose has sufficient enough power to start your vehicle if it has a dead battery.

Because some cheap off-brand charger/jump starters are designed for jump-starting sedans and don't provide sufficient enough power for anything larger.

Final Thoughts On Battery Chargers For Your Car

Diagnosing the reason why your car battery died is something to consider if you are constantly having to charge the battery on your vehicle. 

Parking your vehicle for more than a month? You should disconnect the negative terminal on the vehicle's battery before putting it in storage to ensure that the battery will have power when you go to start it back up.

Even the smallest of battery draw will drain your battery over time. And if you are an ultra pro at keeping your possessions in top condition you will install a battery maintainer to eliminate any doubts when going to fire the engine back up. 

Multimeter Battery Test

Think you may have a bad battery? You can test the battery of your vehicle with a multimeter. Here's how:

Set your multimeter to 20 in the V or 'volts' section to accurately measure voltages between 0 and 20 volts.

Next, touch the red positive test lead to the positive terminal on the battery and the black negative test lead to the negative terminal on the battery. With the car's engine turned off, you are looking for a measurement of 12.6V or above.

If the battery's voltage is below 12.6V, remove it from the vehicle, charge it overnight, and test it again outside of the car the next day. If it holds a charge, then that means you have a power draw that is draining your battery when it's hooked up to the vehicle.

How To Test For Bad Alternator And Battery Draw?

So your car's battery keeps dying on you, and you can't figure out why? Here is a test procedure you can try with a multimeter and a few things you can check over to uncover the mysteries of why your battery keeps dying:

Alternator check

The alternator or generator should be pushing out between 13.5 and 14.5V of electricity to run the vehicle's electrical systems and charge the battery while the engine is running. A bad alternator will drain the car's battery fast.

You can test the alternator with a voltmeter the same way as you check the battery but with the car running.

Again, with the car running set your multimeter to the 20V range, touch the red positive test lead on the positive terminal of the battery and the black negative test lead to the negative terminal on the battery. The measurement should read between 13.8 and 14.4V.

But don't finish your test yet. Get inside the car and turn on the headlights, radio, and climate control system. You should still have a range somewhere between 13.8 and 14.4 Volts.

Parasitic Battery Draw Check

Your battery could be slowly dying because of something inside the vehicle that stays on. Here is a list of electrical components in your vehicle that can drain the battery.

This is also referred to as a parasitic draw. Always start with the highest amp scale. 

Disconnect the negative battery terminal from the battery. With your multimeter set to measure amps(start with a 10 amp range) touch one test leads to the battery cable, and the other test leads to the battery terminal. 

You must have the doors closed and all electricity off during this test. 

Results: You will always see a small and insignificant amount of amperage being drawn from your battery, something like 50 Milli-amps is normal. 

However, if you see that your battery is drawing 3 amps of electricity while the vehicle is parked then its time to locate your fuse box and start pulling fuses until you see the amperage drop significantly.

The powered unit associated with the fuse is what is drawing battery power(like the dome light turned on, for example)

Note: Don't perform this test on the positive terminal of the battery because you can cause a short circuit.
