DC 9V 1A Battery Button Power Cable Tieline For Arduino (9VDC Batt clip)
This is a very useful connector, on one end is snap for the 9V battery, and another end is the standard DC jack (2.1mm). If you are using a 9V battery to power your Arduino board this cable will be handy and perfect for you. The “center pin” of the DC barrel plug is positive and the outer barrel is negative meaning it is compatible with Arduino’s DC barrel jack. The battery snaps into the connector and has 110mm wires – just long enough to give you flexibility in battery placement, but not so long that the wires take up all of your extra space in your enclosure!

Need batteries? You will find our battery selection here
This battery box is designed for use as a nice switchable, portable power pack, and fits any four alkaline or rechargeable AA batteries in series. The body is moulded in black ABS Resin and has a slide on detachable lid which can be locked for extra security through use of a small provided screw. It even includes a very useful miniature on-off slide switch which is very handy for wiring to projects that don't have a switch! Connection is via two flexible stranded red (positive) & black (negative) 26AWG wire leads, which are approximately 150mm in length.
The four batteries are held in series, for a nominal output of 6V DC (6.4V when fresh, 4V when dead), and 4.8V DC for rechargeables (5.2V when fully charged, 4.4V when discharged). Using rechargeables will make this work nicely with nearly any 5V project, with alkalines you may want to put a 1N4001 in series to drop the voltage from 6V down to 5.3V.
