Before trying the pound on the ground with the screwdriver method. Try removing the inner battery beforehand. You should be able to successfully do this by using small needle nose plier or just pull on the small circuit board holding the led. Using a screwdriver method to remove the inner battery still with in it can possibly lead to serious harm.
These
batteries aren't anything to mess around with. If you attempt this while the battery is still within the case, it's likely that you will puncture it or inadvertently cause a short. There will be nothing you can do but toss it as far away from you as you can before it explodes. You'll know that you cause a short when the battery or the case gets scorching hot.
Even while removing the battery. This too can be dangerous.
I have personally and accidentally shorted the battery when removing it from the case. The positive and negative wires were touching when I laid it to rest on my workstation. Fortunately I laid it on top of a piece of plastic, so I smelt it burning and was able to separate the neg and pos wires, but not before the battery was too hot to touch and expanded to double it's size.
Take caution.
There are several ways to remove any connector from any model.
Perhaps the most easiest if you don't plan on salvaging the case is to cut it out with a dremel tool using a cutting wheel. Approximately 1 minute of labor.
Another would be heating the connector end with a heat gun. (careful not to do this too long, the heat gun can reach an upwards of 1000 degrees fahrenheit, which may melt the plastic O'ring separating the POS from the NEG in the connector) Quickly dip the brass end in cold ice water to contract it(try your best to ensure only the brass is quickly cooled), and repeat 2-3 times ending with heat. While hot, screw it into your battery charger for easy gripping and tug and pull. Shouldn't be too difficult.
Another would be the sames steps with the exclusion of contracting and only focusing on heating and replacing the use of the battery charger with a dead atty.
Another would be to cut around the case carefully with a dremell, about 4-5 centimeters before the end of the connector, never having to remove the connector from the case and using the short wires left that is connected to the manual switch or suction switch. This takes precision and usually grasped after 1-2 tries with extra batts, once proper positions are determined of the battery casings innards.
Or as stated above, use blunt force with a screwdriver and drive the connector out.
These are just to name a few. These are what I've tried and works fairly well.
Regardless of the path. The safest would be to purchase the connector from the suggested supplier mentioned above or to remove the battery being housed before attempting any of these.
