Well, believe it or not, I was actually going to get around to soldering it. But this just gives me more incentive to do so. Thank you.I just twisted the wires around the ones of the old battery. It works for now.)The old battery will drain the new one. You need to clip the wires from the old battery (as close to the old battery body as you can get, so the wires are as long as possible.) Twisting the cut wires to the new battery will probably work, use needle-nose pliers so the make good contact.
