    18650 Battery salvage help ?

    I have been given 3 laptop batteries to cannibalise to use in my lamps. I have extracted the batteries and now I need to tidy them up for charging and use.
    How ever the raised positive terminal ends arenít present, they are just flat where the track has been soldered across! I have found replacement heat shrink easily enough but can you also buy new/replacement terminals to attach. If not then whatís the best work around, just a blob of solder?

    Didn't do anything to mine, apart from seperting them and charging them up. Mine came out of an acer laptop battery if that makes any difference

    The casing is steel and doesn't solder readily. The way I always used to solder steel (for RF shielding) was to etch it first with a bit of hydrochloric acid then to solder to the etched section. P.S. As with all soldering DO NOT breath in the fumes!
