    How do I get corroded batteries out of a Maglite?

    The good news was that I found a brand new mag 3c misplaced a few years ago.

    I suspected a problem when it took mole grips and wrench to get the cap off (wrecking the knurling and finish ) and then found the grey powdery stuff.

    So how can I get the batteries out? They are in solid

    cheers

    Vinegar will eat away at the corrosion thus freeing them.

    The other option is to take the head off, take the switch out and hit them out.

    A mechanical advantage tool, e.g.:





    Drill the battery, insert corkscrew, use leverage against tube of the Maglite.

    I've never tried this, but it might work.

    'Tube' the light, like Mad1 suggests.

    Or throw it away because the switch and reflector are probably knackered now, anyway.

    Don't the UK importers have a marvelous returns policy? I can't remember their name but I do remember some amazing tales.

    I think the warranty good as it is doesn't cover battery leaks.

    Get a new one.

    Burton McCall are indeed very helpful and have willreplace worn out parts but the warrenty does not extend to damage causedby batteries.

    To take the head off you make need a silly imperial allen key though (screw located under the rubber switch bit)

    Not sure if this applies to UK folk, but I've heard of those in the US being able to claim for a replacement light from the battery manufacturer. Probably only applies to the big name battery companies such as Duracell though. Might be worth a shot.

    If not then the vinegar/brute force methods are pretty reliable

    Kind a job WD40 was born for. Yes vinegar will eat the corrosion, but so will the solvent in WD40.

    leave it soaked in WD40 for a day or so

    or you could try a cocktail of vinegar and WD40 .. but don't forget the little umbrella

    I had a similar problem with the AAA version, managed to tap the battery out in the end but even with soaking/cleaning the the inside,spring and cap it was never the same. I bought a new one in the end.

    Fill it with WD40 and leave to soak for about a week, shoud'nt be a problem as you lost it for years!, then clean out all signs of the battery leak, and return it to the importers, if you get no joy, insist it is returned to you, and send it to mag light.
    this worked for me, a few years ago.

    Re: How do I get corroded batteries out of a Maglite?

    Thanks for the advice.

    I did initially try WD, but it seems to have evaporated and not loosened them. I did not immerse it though, just a good spray.

    I could not see any allen screw under the rubber switch, but from the bulb end, there are two indentations in a brass ring which look like they are designed for something like the points of circlip pliers. Does anyone now if this ring does hold the switch assembly in place - if so, I'd probably have to make something to unscrew it.

    TBH, it's just so annoying that I've found it again as it is now going to bug me until its all nice and clean and working again

    I don't know if this series of photographs might help?

    Re: How do I get corroded batteries out of a Maglite?

    The vinegar solution worked in my case. I used warm water (actually I used a pot and under steady but relatively low temperature) with a lot of vinegar. I left for a couple of hours. I don't know about the WD40 thing but the vinegar sure works. You should give it a try.
