2 x AA Open Battery Holder with JST PH Connector

This awesome battery holder is a great choice for powering all sorts of projects. It connects two AA batteries in series. The holder's box is quite slim, and two AA batteries can supply around 3V, which is perfect for many low - voltage electronics projects. It also comes with a handy on - off switch! It can fit any standard AA battery. When you use rechargeable NiMH batteries, the output voltage varies 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 ranges from 3.2V with new ones to 2.2V at the end of life, and the nominal voltage is 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 a breeze. First, open the holder and insert two standard AA batteries in the correct direction as indicated. Then, close the holder. To start powering your project, simply turn on the on - off switch. You can choose between rechargeable NiMH batteries or alkaline batteries depending on your needs. Just remember, the output voltage will change as the batteries get used up. When using rechargeable batteries, keep an eye on the voltage and recharge them when it drops too low. For alkaline batteries, replace them when the power output becomes insufficient. As for maintenance, keep the battery holder clean and dry. Avoid exposing it to extreme temperatures or moisture. If there's any dirt or debris inside the holder, gently clean it with a dry cloth.
