rust on rechargable AA batteries

Hello:

I've noted that I have some light rust on the positive terminals of the AA rechargeable batteries I use in my strobe.

I've cleaned the rust off, however, I'm sure it will come back.

Any ideas or solutions to keep the rust at bay?

I was thinking of either a light coating of oil or o-ring grease to stop rust forming or getting worse. I'm not sure if this will interfere with the batteries themselves or the connection.

Thanks....IAIN

I wipe off my batteries when I change them because, invariably, salt residue builds up and causes rusting. I have some batteries in the same condition but they are still usable. I change my rechargeables every two years, toss em them bith the bullet by purchasing 40 more.

Hi Kelpfish:

Yes I also wipe my batteries down after use - but these ones still rusted.

Do know of a thin coating of oil or pertrolleum jelly/o-ring grease will cause problems for the batteries and/or strobe connectors?

Like you I also replace batteries - but every 3 years.

To ensure reliability I use my batteries on and off when not diving (GPS, etc) and try and maintain a full charge most of the time between dives. So far, no battery has failed me.

Thanks....IAIN
