    What is lithium-ion batteries?

    B003I3RGYO UltraFire 123A 800mAh 3.0V Rechargeable Batteries 2 Pcs

    Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery in which a lithium ion moves between the anode and cathode. The lithium ion moves from the anode to the cathode during discharge and in reverse, from the cathode to the anode, when charging. Lithium-ion batteries can be formed into a wide variety of shapes and sizes so as to efficiently fill available space in the devices they power. They're generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds. This translates into a very high energy density for lithium-ion batteries. Plus there is no issue with the memory effect, like the nickel-cadium does. When a nickel-cadium battery is recharged before it discharges the majority of its power, it essentially "forgets" that it could fully discharge to begin with. This problem is termed the memory effect.

    What is lithium ion polymer rechargeable battery?

    It's a high energy density, 3.6V/3.7V battery that is not compatible with ordinary batteries, but is widely used in the portable equipment market. It uses lithium metallic oxide (LixCoO2, LiNiO2, LiMnO4) in its positive electrode (cathode) and carbon material (LiXC6) in its negative electrode (anode), with electrolyte LiPF6, LiAsF6 etc, and the Lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge, namely Rocking Chair Batteries (RCB).

    Rechargeable Lithium Batteries

    Lithium ion polymer rechargeable battery similar to the Lithium-ion but with a solid polymer as electrolyte. Some gelled conductive material is added to promote conductivity. It utilizes the latest technology to become available for consumer use in products such as portable computers, PDA, cellular phones, blue tooth, portable DVD and military electronics etc. Lithium-ion polymer batteries have high voltage per cell, and excellent energy on both a weight and volume basis. Additionally, they can be made in very thin and large footprint configurations. Lithium-ion polymer batteries use liquid Lithium-ion electrochemistry in a matrix of conductive polymers that eliminate free electrolyte within the cell. For operating effectively over a broad range of temperatures and conditions, Lithium-ion polymer batteries contain no metallic Lithium anodes.

    About Rechargeable Batteries

    123A Batteries

    • Function
    • Sometimes called a storage battery, a rechargeable battery consists of multiple cells. This enables the electrochemical reaction that powers the battery to be reversed. Using a charger, these batteries can be recharged many times. Rechargeable batteries are used in automobiles, consumer electronics, storage for solar arrays and electrical vehicles.
    • Types
    • The most common types of rechargeable batteries are lead-acid, nickel cadmium, alkaline, nickel metal hydride and lithium ion. Lithium ion batteries are considered the most advanced rechargeable battery type and are used in most contemporary consumer electronics.
    • Size
    • Rechargeable batteries come in many shapes and sizes from automobile lead-acid type batteries to laptop and small digital camera batteries. The size is determined by the type of technology used and the design of the device in which the battery will be placed.
    • Features
    • The main feature of a rechargeable battery is self-evident--it can be charged multiple times. Secondary features that differ depending on the type of battery include:
    • Self-Discharge: This effect occurs within the battery cells causing the battery to lose power over time even when not in use.
    • Memory Effect: An effect mostly witnessed in Nickel Cadmium batteries, the battery seems to lose its maximum energy capacity if charged multiple times without being fully discharged.
    • Energy-to-Mass Ratio: This refers to the energy density of the battery.
    • Currently, Lithium ion batteries are the best performing rechargeable batteries if considering the above features.
    • Considerations
    • Many people avoid rechargeable batteries when given a choice because of a perceived higher cost. When you consider that rechargeable batteries can be reused multiple times, the savings of using them as opposed to one use batteries becomes clear

    • 2 x UltraFire ICR 123A 800mAh 3.0V Rechargeable Batteries

This item was shipped the day after I ordered it. Nice to see it. It was exactly what I needed for my device for a backup battery. It's a pretty cheap deal, too.

Good deal

Battery arrived fast and works great just as advertized. This is my 2nd one. I expect this one will do the same and you can't beat the price.

at this price I was not sure. Got the battery, charged it and my problem was solved. It actually looks to be a good battery. Now I do not have to recharge during the day anymore.
