Many projects that are brewed are usually small in size and do not require a large battery to function, especially if a solar panel is also used where you use a LI-Ion or NiMh battery in the 2 x AA holder that can be used during the day. be charged and used in the evening and night. Keeping a battery holder 2 x AA is a very handy solution.

If you are going to use alkaline batteries, keep in mind that you replace them on time. This is because today's alkaline batteries, especially the cheap versions, are known to leak very quickly. Once an alkaline battery has started to leak, the acid will corrode the contacts, rendering the holder almost unusable. The same goes for the very cheap and still available zinc carbon batteries. The acid from both types of batteries can also end up on your project, causing your construction to malfunction and that would be a waste of your time and material.
