This awesome battery holder is a great choice for powering all sorts of projects. It connects two AAA batteries in series. The open - box design is nicely slim. With two AAA batteries, you get around 3V, perfect for low - voltage electronics projects. There's also a handy on - off switch! It fits any standard AAA battery. If you use rechargeable NiMH batteries, the output voltage ranges from about 2.7V when fully charged to 1.8V at the end of their life, with a nominal voltage of 2.4V. For alkaline batteries, the output goes from 3.2V with new ones 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, and it uses a genuine JST connector to prevent 'catching and tearing' in JST connectors.
Using this battery holder is easy. First, open the battery holder and insert two AAA batteries. Make sure to follow the correct polarity. You can then connect it to your project using the JST PH connector. The on - off switch allows you to control the power supply conveniently. When using rechargeable NiMH batteries, keep in mind that the voltage will change as they charge and discharge. For longer battery life, use alkaline batteries if possible. As for maintenance, keep the battery holder clean and dry. Avoid exposing it to extreme temperatures or moisture. If the JST connector gets dirty, you can gently clean it with a dry cloth. And always replace the batteries when the voltage drops too low to ensure your project works properly.
