Alright, wait a minute guys. When I said get a bigger soldering iron, I didn't intend for the user to hold the iron on the terminal until it turned freaking red-hot (and consequently fry the batteries). Obviously, if done properly, the bigger (higher wattage) iron means that you don't have to sit there holding the iron to the terminal for several minutes while it heats up. It will reduce the stress factor for the user by making the contact time shorter. In order to achieve the same temperature on the terminal for the solder to bond, the same amount of heat would transfer to the plate connection inside the cell no matter what the wattage of the iron; causing the same amount of "damage" in either case. Just be careful to hold the iron on the contact *only* long enough to allow the solder to bond. I guess my original advice should have been labeled for experienced solderers only ;-) - Bill ----- Original Message ----- From: "Drew Glasbrenner" <glasbrenner@mi*.co*> To: "Rich Lesperance" <richl@uf*.ed*> Cc: <techdiver@aq*.co*>; "Cave listserv" <cavers@cavers.com> Sent: Monday, February 14, 2000 5:51 PM Subject: Re: soldering light batteries > Rich....Easy on the heat too...too much on the terminals will damage the > plate connection inside the cell.
