Best Selling Car Battery Chargers

A car battery charger (also sometimes known as a jump starter), it would be fair to say, is a must have accessory that should be stored in every drivers car trunk. The most obvious reason for this is having the ability to start your vehicle in emergency and other roadside situations without the need for a second vehicle (and therefore its onboard engine battery) nearby.

Simply, portable access to the battery power surge you need to get your car safely home.

The Top 5 Car Battery Charger Reviews

Which are the top Car Battery Chargers available in the market today? Here is a list of some that are successful and among consumer favorites.

Battery Tender 021-0123 Battery Tender Junior 12V, 0.75A Battery Charger

The Battery Tender Junior is a 12V, 0.75A Battery Charger. It will not only charge your battery but also maintain. This ensures that it is ready to go when you need it! It's lightweight, fully automatic and extremely easy easy to use.

The microprocessor that is fitted in the car battery charger automatically controls the charging and maintaining functions. It is specifically designed to extend the life of any lead acid battery commonly used in automobiles and smaller vehicles. It can also recharge a fully depleted battery back to a full charge without overcharging. It will then automatically switch to float or maintainer mode for an indefinite period of time.

Pros

  • Light weight and compact
  • Spark proof during lead connection
  • Can be used with all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell)
  • Automatically switches to float / maintenance
  • Two color LED indicator light

Cons

  • More suitable for maintaining fully charged batteries.

Verdict

On the positive side, this battery charger is extremely compact and light weight. It is supplied with a reasonable long power cord for plugging into the mains. It is also supplied both with two types of battery connectors. One type, a set of alligator clips, for temporary attachment to your battery, and a set of ring terminals, for permanent attachment. Overall, this is a very capable product. It works amazingly well at keeping your batteries in top condition.

BLACK+DECKER BM3B 6V and 12V Battery Charger / Maintainer

The Black & Decker BM3B is both a battery charger and a battery maintainer. It supports charging both 6 volt and 12 volt batteries. It is fully automatic in that it charges the battery when required and stops when the battery is fully-charged. It's built-in circuit protection prevents overcharging, reverse polarity or short circuit.

The charger can be used for battery maintenance as well as common lead acid batteries of all sizes, including marine deep cycle batteries. It is supplied with three types of connectors: DC accessory plug, battery clips, and battery ring terminals.

Pros

  • Light weight and compact
  • Battery Maintainer for use on 6V & 12V battery
  • Charges 6 and 12 volt AGM, GEL and WET batteries
  • 3 choices of connectors for connection to battery
  • Automatically switches between charging mode and float mode

Cons

  • Only outputs 1.5A of current.

Verdict

The low output of the Black+Decker BM3B charger means that it will take at least and over night charge to recharge the average car battery. However, when used as a trickle charger, it will top up your battery if it is low and keep it at maximum charge without over charging.

If a trickle charger is what you are looking for, then this will prove to be a good buy. However, if you need a more powerful battery charger that charges a normal car battery quickly, then you should consider something else.

Why Should You Get Hold of a Car Battery Charger?

If your car does not get driven enough to keep the battery up to charge your battery will eventually drain. In cases like this, you would tend to connect the battery charger at least an hour before you intend to drive the vehicle. This will ensure you avoid any potential frustration and delay.

If you have ever experienced a battery failure, you know why you wish you had previously bought a battery charger. It's also important to remember that a sudden fall in temperature can suddenly cause problems with a battery you thought was previously fine.

Pointers to Help you Choose the Best Car Battery Charger

Size and Voltage

What size of battery do you intend to charge? Batteries for cars will be smaller than those for a truck. This will determine the charging capacity of the charger.

Some smaller vehicles, like a garden sit on mower, may be fitted with a 6-Volt battery. You would need to consider battery chargers that can charge both 12 volt and 6 volt batteries.

Battery Type

The majority of batteries found in vehicles are lead acid batteries. However, other types include AGM, Gel Cel, or Deep Cycle. You must check the suitability of any battery charger to charge these more uncommon types.

Manual or Automatic

Car Battery chargers can be designated as manual or automatic. The fully automatic chargers are able to detect when the battery is fully charged and will automatically switch to a maintenance mode or trickle charge. This protects the battery from being overcharging.

Conclusion

These units are all very popular in the marketplace, with each product having its own features and benefits, pros and cons. Some car battery charger units are simpler and more raw in their approach, while others are designed as multi-purpose power pack type products, where the user has access to not only the ability to jump-start a car, but also inflate tires and power up cell phones or laptops via AC/DC power, just to name a couple of the extra functions.

At any rate, there is a unit suitable for every consumer. The main question that the potential buyer has to ask is simply: what is it that I REALLY want and need from such a product?
