2 x AAA Battery Holder with On/Off Switch JST PH Connector

This amazing battery holder is a must - have for all electronics projects. It connects two AAA batteries in series, delivering about 3V, perfect for low - voltage electronics. The holder has a very sleek design, making it both stylish and practical. It comes with a cool on - off switch, which is super convenient. It fits all standard AAA batteries. When using rechargeable NiMH batteries, the output voltage varies from about 2.7V when fully charged to 1.8V at the end of its life, with a nominal voltage of 2.4V. For alkaline batteries, the output ranges from 3.2V with new batteries to 2.2V at the end of life, with a nominal voltage of about 3V. The polarity matches our 2 - pin JST cable and Li - Ion/Poly batteries. It uses a genuine JST connector, so there's no risk of it getting caught or torn in JST connectors. It's a great upgrade for the battery packs that come with micro:bit devices, as you can easily turn off the power without having to pull out the batteries.

Using this battery holder is a breeze. First, open the holder and insert two standard AAA batteries. Make sure to follow the correct polarity. Once the batteries are in, close the holder. You can then connect it to your project using the JST PH connector. To turn on the power for your project, simply flip the on - off switch. To turn it off, flip the switch back. When using rechargeable NiMH batteries, remember to recharge them when the voltage drops to a low level. For alkaline batteries, replace them when they're almost out of power. Keep the battery holder in a dry and cool place. Avoid exposing it to extreme temperatures or moisture. If the JST connector gets dirty, you can gently clean it with a dry cloth.
