Iam making a project that involves the use for L293d motor driver circuit and i realized there is a slot for providing 9v to run the motors but after purchasing 3 9v batteries and using them for testing. I found out these batteries run out of power in 15 mins of use. Please suggest a good battery that can be used to run this kind of project for a long duration.
Choose a 9 volt rechargeable battery for better use
The above link is of rechargeable 2500mAh Duracell battery. They should work nicely in your project.
