7.4v lithium ion battery

A portable power supply has become the lifeline of the modern technological world, especially the lithium-ion battery. The benefits of lithium batteries have evolved and improved since their first appearance on the market in the 1990s. Today, they are essential as an energy source for all those daily products and vital in our work and professional life. Lithium batteries are also used by the many industries.

1, What is a lithium battery and how does it work?

A lithium-ion battery is a type of rechargeable battery that is charged and discharged by lithium ions moving between the negative (anode) and positive (cathode) electrodes. In other words, it is an energy accumulator that allows its use by a device it is attached or connected to. Once consumed, it can be recharged and reused in a limited way.
Because lithium-ion batteries are suitable for storing high-capacity power, they are used in a wide range of applications, including consumer electronics such as smartphones and PCs, industrial robots, production equipment and automobiles.  

The operation of the lithium battery is based on the use of lithium salts as an electrolyte that eases the reversible electrochemical reaction between the cathode and the anode. Lithium ions flow from cathode to anode, sending this current and feeding the device to which the battery is attached at that time.

2, What types of lithium batteries are there?

There are different types of lithium batteries.

Lithium Cobalt Oxide
Lithium cobalt oxide batteries have a very high specific energy. Because of that, they are used for mobile phones, laptops, and cameras.

Lithium Manganese Oxide
Lithium manganese oxide batteries are very temperature-stable. They are safer in comparison to Lithium-ion batteries.

Lithium Iron Phosphate
Lithium iron phosphate batteries have low-resistance characteristics. They make sure that the battery is safer and more stable.

Lithium Nickel Manganese Cobalt Oxide
They have a high specific power or a high specific energy density.

Lithium Nickel Cobalt Aluminum Oxide
Lithium nickel cobalt aluminum oxide batteries become of importance in electrical drivers and electric power trains.

Lithium titanate
The lithium titanate battery charges really fast. It is used for public transportation like electric busses.

7.4 Li ion battery FAQ

How long does a 7.4 Li ion battery take to charge?

One and a half to two hours.

How do you charge a 7.4 V lithium-ion battery?

Connect the mobile phone AC adapter or the power bank to the USB IN port via a USB cable. The CHG charge indicator (red) flashes rapidly indicating no battery being inserted. Connect a 7.4V lithium battery to the BAT IN port. CHG is always on indicating the battery being charging.

How long does a 7.4 V Li ion battery last?

7.4 Lithium-ion rechargeable battery can provide 12-18 hours working time for two-way walkie-talkie

How do we maintain our batteries?

The battery of the walkie-talkie is an important accessory for the best performance of the business radio. For our preppers and educators, our two way radios are facing long-term unused conditions, so how should we deal with our batteries in this case? In the Battery Maintenance Guide blog we have a detailed account of battery maintenance.
