Why Rechargeable Batteries Are Needed

Rechargeable batteries come in various types. The purpose of their creation is dependent on the equipment of the spectrum, with which they can be used. Originally, they were designed as an alternative to conventional batteries.

The main purpose of the batteries is providing food particular device without connecting to the AC power. To do this, the batteries need to accumulate charge and to be able to keep it until the immediate use of the device. Unlike conventional batteries, rechargeable batteries have properties to restore its charge. Many batteries were created as an alternative to the usual batteries. Ability reusable makes these devices more convenient to operate and economical. And the flashlight uses (e.g. the Ultrafire 18000 lm flashlight or Nitecore Intelligent I2) rechargeable batteries, you need to get the Nitecore Intelligent I2 car adapter to charge them.

The battery is a set of batteries connected in parallel or in series. In most cases, the connection is carried out sequentially. This method is needed to increase the final output voltage. This allows the battery group, the output voltage of each of which is significantly lower than the general. This scheme allows to increasing the overall capacity of the battery. Typically, parallel connection is used to create batteries for the devices, which is necessary to ensure long-term operation without recharging.

Currently, all mobile devices use batteries to operate. These include mobile phones, laptops, smartphones, tablet PCs, mp3-players and so on. In most cases the use of lithium-ion batteries. Particularly important characteristics of the battery may include the following parameters: Capacitance, voltage, efficiency and durability is very important to understand that the batteries have a particular resource that is wasted during use.

Individual Light Sources, Flashlights or Unusual Lanterns?

Individual light sources rescuers in the darkness of the pantry, barn, cellar or closet, flashlights - irreplaceable thing in the house of every person. How much more original and varied may be those very little things, we have already seen in the long-standing review of unusual lanterns. The second part of lanterns review will continue this theme today.

Water, juice, beer, soda and even urine - absolutely any liquid that can be found nearby, can serve as a source of energy for this amazing flashlight from Japanese inventors. Its name Water Powered Torch speaks for itself. So you can feel safe, I did not have to be in whatever the deep woods with this new product the Japanese industry. 

Flashlight (e.g. the T6 flashlight) needs batteries to operate. A flashlight, which in itself is a battery, invented the designer Lu Yi. Externally, the concept did not distinguish from ordinary penlight batteries. Is that the LED light and the On/Off button. It will be given an additional purpose. Battery Light called device is a light source for both human and energy source for, e.g., watches, cameras or vehicle winding. 


And also lanterns can help to lose weight for people with excess weight. Not all, but a conceptual device Jumping Light, which is a flashlight built into the rope, as if he could. Thus, these lamps consume kinetic energy. And the more a person jumps, the longer it will work then the flashlight. BTW, you can select the Flashlights or Unusual Lanterns at Banggood. Besides, you can easily get other lights and accessories (e.g. magic faucet) there with high quality and reasonable prices.

Powerful LED flashlight with CREE Q5

In the course of the reviews and to provide their own passive safety, I was commissioned in the lantern on the high-power LEDs CREE Q5, which generous dealer offers a complete whole slew of utilities such as: the holder on the steering wheel, extension tube under the battery size 18650 and compartment for three batteries AAA. An overview and testing of this wonderful flashlight, I propose to read this article.

Performance Claims
  • LED: Cree Q5
  • Housing material: aluminum
  • Modes of operation: full power, half power flicker (strobe)
  • Power supply: 3 batteries (or battery) or 1 AAA battery type 18650
  • Size: ~ body diameter 26 mm, length of lamp 100 mm ~, format by AAA and 3 ~ 110 mm, with an extension ring for 18650
  • The maximum distance coverage (in a focused mode): ~ 200 m
  • Current consumption: ~ 1000mA


Equipment
  • LED CREE torches (without batteries)
  • Extension tubes (for mounting the battery type 18650)
  • Compartment AAA batteries
  • Holder on a bicycle wheel (with spacers under the different diameters)
  • Lace (like on the wrist, but too narrow for this)


Test Results
  • Compared with the usual reflex, this flashlight provides uniform light spot all over him at range. Despite the power of the stain and illuminates the road, while riding a bicycle, the road is clearly seen in the spot light, and beyond.
  • Mounted on the steering wheel I did not like, because the design looks flimsy and material of which it is made, too, are not credible.
  • LED Power imposes certain restrictions on the duration of the work, so the best option of its power - it's all the same battery 18650. AAA batteries, it seems to me, actually use only as a backup power supply.


Conclusions
LED is really powerful, and the ability to focus, too, cannot be called useless function - using a narrow beam to the roof finishes and 16-storey building at a distance. So the conclusion for me is simple: you want a cheap and powerful flashlight, take this. BTW, you can select the CREE flashlights at Banggood. Besides, you can easily get other lighting accessories (e.g. the 10180 battery charger) there with high quality and reasonable prices.

How to Charge the Li-ion Batteries

Lithium-ion batteries are used as a source of energy in laptops and cell phones, video cameras and other consumer electronics (e.g. Manker Rambler flashlight). They are demanding to the voltage at the time of charging, and therefore should be charged by special charges.

Do not allow a complete discharge of batteries. They do not tolerate it and are easily damaged. It is recommended to maintain the charge level of at least 75% of the total. Lithium-ion batteries are charged on a "constant current / constant voltage". Unlike conventional batteries, lithium-ion requires a higher voltage per cell (about 3.6 V). If, for example, lead-acid batteries can be recharged slowly after full charge, the lithium ion devoid of such ability.

Ensure that the battery charging conditions. Lithium-ion batteries can operate at temperatures from 0 to + 60 ° C. In the negative temperature conditions, the battery stops charging them. A distinctive feature of the lithium-ion batteries (e.g. the Xtar 18650 battery) is a very high sensitivity to increased stress at the time of charging. There are times when the batteries from this light. To avoid such incidents, modern lithium-ion battery is inserted into a special electronic board which disconnects the battery if it is overheating. Another way to avoid overheating the battery is the use of "smart" chargers. Most modern chargers can determine the time of the full battery charge current on and off independently.

Connect the battery to the charger, and it, in turn, connect to the network. Some chargers allow you to choose the maximum current. For example, low-power batteries can be recharged current of 500 mA, and more powerful batteries - current of 1000 mA. This makes it possible to reduce the charging time. After charging, disconnect the battery from the charger. If the battery is not used for a long time, it is better to charge it at 60-70 percent.

Rechargeable Flashlight - What and Why

Total darkness never aroused much enthusiasm in humans. Only amateur photographers in the recent past were immersed for a while in total darkness, and then only briefly. Today, to break through the darkness allows the lantern light, and most modern of them - the lantern battery.

Lantern market today offers two basic types of items - lights on the battery and accumulator. Use the batteries can be the case if the light for you - the tool that you use rarely. In this case cannot buy a few batteries, even if one or two times. BTW, you can select the cheap LED lanterns at Banggood. Besides, you can easily get other lights (e.g. cheap LED driver lights) there with high quality and reasonable prices.

However, if you are a lover of night tourism or fishing, as well as, if you often have to go home in the dark nooks and crannies - the time to think about the lantern battery. The main advantage this product is that you do not have at the very wrong time to look for a shop where you can buy food items. It is enough to charge it, and the problem will be solved. In addition, buying batteries, we cannot say exactly in what conditions they were kept, and how much they will last. You agree to remain in the dark somewhere in the woods - not the bright prospects. With such a battery is no problem, because you initially know how it will be enough charge. Before buying a lamp is necessary to define the task - which is to cover the lantern. In their designs and target orientation, there are classic, headlamp, underwater, road, biking, camping, professional, and other handheld lights.


If you need to have a free hand and directed a beam of light in front of you, you cannot do without a headlamp. To illuminate the room, use a professional flashlight, which can be installed permanently. There are also special lights that come with some kind of tool, for example, a drill or screwdriver.

Flashlight Keychain and EDC Lantern for the City

Earlier, I posted an article about choosing the EDC flashlight (e.g. Astrolux MH10). I recommend reading it if you have not read it. The article discusses the usefulness of those or other lamps as a subject for daily wear. Today we will look at the feasibility of carrying a flashlight flash drive and use it as an option for the city of EDC.

What should be the EDC flashlight (e.g. Astrolux S41 ) for the city?
In a previous article on the lanterns we understand that when choosing a subject as EDC need to decide what we demand of it in terms of functionality, size and cost. In some situations where we know clearly that may require a bright flashlight, it is advisable to take the light source slightly larger, for example, any type of those that have been described and reviewed in the video previously. But in most cases you have enough ordinary flashlights flash drive.

It should be noted that this point of view it is relevant for a large city. If you live in small settlements, it is possible that the flashlight keychain cannot cope with your daily tasks.

Currently available are many models of small choices. You can order keyring flashlights (e.g. Astrolux M01) on the site, Banggood.  Simply choose the option that you prefer.
