6xAA Battery Holder with DC2.1 Power Jack

This amazing battery holder can accommodate 6 AA batteries. It can transform into a 7.2V rechargeable battery pack using NiMH / NiCd cells or a 9V battery pack with alkaline cells. It comes with a DC2.1 Powerjack, allowing you to plug it directly into an Arduino. Here are the key specs: 6 cells, AA battery type, storage at 25°C (77°F, room temperature), max operating temp of 80°C (176°F), dimensions of 93x57x15 mm(3.66x2.24x0.59'), 76mm(2.99') between mounting holes, and 3mm(0.12') mounting hole diameter.

Using this battery holder is a breeze. First, insert 6 AA batteries into the holder. If you're using NiMH or NiCd cells, you'll get a 7.2V rechargeable battery pack. With alkaline cells, it becomes a 9V battery pack. Then, simply plug the DC2.1 Powerjack directly into your Arduino. When it comes to storage, keep it at room temperature (25°C or 77°F). Don't let it operate in temperatures above 80°C (176°F). As for maintenance, make sure to keep the battery holder clean and dry. Check the batteries regularly and replace them when they're low on power.
