    When it comes to 1.5V batteries, everyone will immediately think of the most common AA and AAA batteries. These are disposable Alkaline batteries. Many household and handheld devices have been built to use those cells and voltage of 1.5V, such as remote control, kid's toys, wireless mouse, wireless microphone, etc.

    Alkaline AA/AAA batteries cost effectively but they have high internal resistance. This reduces output. Therefore they last shorter than the rechargeable cells when used in high drain devices like digital cameras, which means you need to change batteries much more frequently. Therefore, many people want to know “can I use 1.2V batteries instead of 1.5V?”. Yes, you can do it. The Alkaline battery has a voltage of around 1.5-1.6V but its voltage quickly drops to around 1.25v under actual load, and around 1V when its almost discharged. The voltage output is similar to that of the 1.2V NiMH batteries.

    However, you need to face a problem with NiMH rechargeable batteries that if you have a device that requires 4 or more cells in series then it can create a voltage drop due to the low voltage of NiCD / NiMH rechargeable batteries and the device might refuse to run or power on. So the ideal way is to replace alkaline with lithium. XTAR lithium AA batteries produce 1.5 volts, so they can be used to replace any regular alkaline AA units in most cases. Also, XTAR released a new battery charger BC4, which supports charging the 1.5v rechargeable lithium batteries.

    What’s the truth about the 1.5V rechargeable lithium batteries? As we all know that Lithium-ion batteries normally operate 3.7V per cell, but XTAR put circuitry inside the cells to reduce the voltage to 1.5 volts. The output of the XTAR 1.5V rechargeable lithium battery is a constant voltage of 1.5V. Therefore, devices such as racing cars, remote controls, electric toys, etc. that use this battery will also maintain stable performance.

    XTAR BC4 battery charger is the best partner of the 1.5V rechargeable lithium battery. It can charge 4 pieces of batteries at a time. It uses a constant voltage method with charging current 500mAh. The input port is the popular USB-C with current up to 5V 2A.

    The BC4 uses independent four-bay circuit and supports mix-charging of 1.5V Li-ion, and 1.2V Ni-MH/Ni-CD batteries. It intelligently detects the battery type, battery quantity, and the input power, and then select the optimal charging strategy to ensure the maximum output power and higher charging efficiency. So with XTAR BC4 charger, all your rechargeable AA/AAA batteries can be charged safely.

    The size of the XTAR BC4 is L80mm x W75mm x H27mm, which is very small. Therefore, BC4 can be hold easily by one hand and put into your pocket, very convenient no matter for daily carry or for outdoor trips.

    XTAR BC4 can be also used as a power bank, with output 5V 1A. When your mobile phone is out of power but you have no other charging devices at that time, this function will solve your power needs. Just put four 1.5V rechargeable lithium batteries into the charger, and connect the charger to your mobile phone with a USB cable. If you have no 1.5V cells, the BC4 can also support disposable Alkaline batteries and 1.2V NiMH batteries.

    There is another sweet design for BC4. That is the LED lighting. Install four 1.5V Alkaline or rechargeable lithium or 1.2V NiMH batteries into the charger, press and hold the button for 2s can turn on the LED light for close-up search and other emergency use in the darkness.

    In summary, if you need many 1.5V batteries in your daily life, and if you are an advocate of environmental protection and cost saving, why not consider using XTAR BC4 battery charger and XTAR 1.5V rechargeable lithium batteries? You will benefit from them.
