I have a device that uses 4 small, small batteries. If I feed it with 4 large batteries will the durability be greater? Is there no danger of me burning the device?
Four small batteries or four large batteries provide 6 V which means that in both cases the device will work normally, without problems, because even the larger batteries can supply more current, the device will only drain the current it needs. As their power supply capacity is higher, they can supply current for longer, the durability of larger batteries will also be greater.
