    Many electrical products use one or more CR123A disposable lithium batteries. Because they are not rechargeable, customers always need to purchase a large number of batteries. The nominal voltage of the CR123A battery is 3V while the normal rechargeable lithium battery on the market of the same size reaches a voltage of 3.6V-4.2V (±0.05V) when fully charged, which will damage the electrical products because of the high voltage. The output voltage and size of the Weltool UB-123A are exactly the same as CR123A. It can be recharged 300 times, eliminating frequent purchases of single-use CR123A batteries, lowering operating cost and protecting the environment. 

    Please pay attention that the incandescent flashlight can't use UB-123A.
    Placing the protection circuit with the battery core at the anode (positive terminal), combined with the steel outer shell, UB-123A effectively prevents the danger from impact, such as short circuiting, without increasing the diameter of the battery .There are four protection circuits for: Overheating, Over-charging, Over-discharging, and Short-circuit protection! Anode protection circuit includes the Micro-USB charging port, enabling direct charging using USB cables connected to a 5V adapter, a PC USB port, or any portable power banks. While it is being charged, the indicator lamps on the battery will display the charging status.

    The anode (negative terminal) of the battery features a protruding cap for improved connection to springs or other PCB surfaces. This improves functionality when the battery is used in series during application. UB-123A also has an improved exterior wrap to protect the battery from damage and retains the rugged dependability of Weltool!
