On the off chance that you've ever gotten into electronics hacking, you've likely had the fantasy of most gadgets demolished for you. For instance, 9V batteries are fundamentally only six AAAA batteries bound together.
As Reddit user usgiorgi calls attention to, numerous bigger locally acquired batteries contain an accumulation of litter batteries. For assembling reasons this bodes well. It's likewise helpful in case you're building a project and need to change your power source.
Whatever remains of the segments are additionally convenient. Reddit client CaptainKozmoBagel brings up that you can rescue the top of a dead 9V battery to make another 9V connector with a tad of wire. Remember, that you shouldn't attack only any old battery. Lithium particle batteries (like the kind in your cell phone) can blast in the event that you attempt to open them up. 9V batteries, however, are really sheltered to tear down.
if you need a new 9v connector, just solder an old 9v’s top up to the leads.
