Do You Know What The Different Features

Do you know what the different features of a lithium battery charger are? A lot of technical jargon is thrown around when marketing lithium battery chargers and Lithium Batteries when explaining their features. For most buyers, it gets hard to connect the features of the product and the benefits they stand to get from them. So, if you are interested in buying a lithium battery charger and a lithium battery, here is a simple explanation of their various features and why these should matter to you.

Important Lithium Battery Charger Features

Fast charging: Unless you have used a super-fast lithium battery charger, you may believe that the hours of charging your current charger takes to get your batteries up and running is the best you can get. Wrong! You can actually get a 18650 battery charged to full capacity in as less as 2-3 hours if you have a lithium battery charger that offers the optimal charging current.

Unfortunately, the current breed of chargers, with the exception of a few, seldom go over a charging performance of 500 mA. But, what you need to get is a super-fast yet safe lithium battery charger with a charging current of at least 1000mA. This means that for a 2200mAh 18650 battery, it will take only 2.2 hours to charge your battery instead of 4.4 hours with the standard 500mA battery, thus saving you over two hours of charging time. This is even more important when it comes to charging a high capacity a 5000mAh 26650 battery. With the standard charger you will need to wait for 10 hours until your battery is fully charged, while when using a fast charger with a 1000mA you will only need to wait 5 hours until you battery is fully charged, saving you 5 hours of charging time.

Ability to Charge both 18650 and 26650 battery types: These are most popular battery types, so make sure that your charger can charge both types of batteries. This will save you money and space since you will need to purchase only one charger instead of owning two chargers one for each battery type.

Trickle charging: This feature both protects and enhances the performance of the batteries. With trickle charging, almost 75% of the battery gets charged at warp speed, and then the charger goes on trickle mode. This helps in two ways. With trickle charging, there is no risk of overcharging which can damage the batteries and can even lead to spontaneous ignition. Also, without this feature, you will end up with less than 100% charged batteries, as it is safer to undercharge than over charge.

Reverse Polarity protection: With protection against reverse polarity charging, you can be sure that you batteries will never be damaged owing to an accidental lapse. If you place the battery in a reverse polarity protected charger the wrong way in, the charger simply won’t start.


Smart charging:
NO, an LED display does not make a lithium battery charger smart. The smart charging feature should offer two layers of protection. One, it should stop the charger once the batteries are at full charge and two, it should protect the battery against reverse polarity charging. Both of these mechanisms help to prevent fire. So, LED display or not as long as the charger has these two built in design mechanisms, it is smart and safe.

Fire retardant materials: Lithium batteries can ignite, as has recently happened with the Galaxy Note 7 cell phones which were recalled due to a problem with the lithium battery/charger that caused some of them to spontaneously ignite. For this reason you must sure that your charger is made of fire retardant materials.

UL certified: Lithium batteries are very us useful, they have a high capacity and can be recharged many time, however they have they can ignite, so it is very important to have a high quality charger which is UL certified, this will make sure that your charger complies with the American Safety Standards.

Important Lithium Battery Features

18650 or 26650 Battery: These are the most popular lithium battery types used in the brightest tactical flashlight. The main difference between them is that the capacity of the battery, the 18650 battery will have around 2000mAh and the 26650 battery will have around 4000mAh. So if you have a tactical flashlight which can operate with a 26650 battery you will have twice the run time than a flashlight which can operate only with a 18650 battery.

Reverse polarity protection: Since there are many chargers which are not reverse polarity protected, it is important that your battery is reverse polarity protected. Having this feature will protect your battery in the event that you accidentally charge the battery the wrong way and will prevent it from being damaged.

Batteries real capacity: Unfortunately many low quality batteries are sold on the market or supplied as part of a flashlight kit. One of the things you will notice first is that the capacity written on the battery is far from real and you charge your battery after only an hour or two of use. If you want to know the real capacity of the battery you need to test it like in the below picture or at least have your vendor supply you with proof of capacity. Another way to have some indication to the batteries real capacity is to weight the battery, you will surprised to see that many batteries are very light in weight which is a clear indication that their real capacity is very low.

The ZR1 lithium battery charger made by Brightex Technologies along has all of these features and more. In fact, the combo pack not only includes a UL (Underwriter’s Laboratories) certified charger that works for both 18650 and 26650 batteries but also contains a protected 18650 battery that offers guaranteed 2200 mA of power. So, you get twice the protection and twice the value for your money!
