I own a Yema Bipolar Expedition watch that requiresa battery replacement.  Can you handle such a service or recommend a possible source?  Many thanks - Walt de Lorrell, San Diego California,USA

This forum does not sell or advertise sales or services of any kind. Battery replacement is normally done at any watch shop, jeweler, or mall booth. Many people also like to replace batteries by themselves, for which a basic tool set is enough.

Do not handle the battery with your fingers as this can shorten its life, you need to use plastic tweezers. If you are not sure what you are doing, do as jdm says.

I tried  plastic tweezers and gave up on them for changing batteries. Poor grip especially for the big sizes, they make handling awkward.

Hi  Changing batteries requires a few tools and common sense, Touching the terminals with your fingers causes the battery to discharge through  the body  and therefore shortens the life of the battery so avoid touching with the bare hands, Insulated tweezers or plastic tweezers can be used and settle into place using a plastic tool or peg wood. Or if you are a purist wear latex gloves or finger cots to avoid any damage.

Clearly that may happen only if both terminals are touched at the same time, something that is easily avoidable. Also, body conductivity is such that occasional brief contact will have no discernible effect to the battery charge.

The reason to use nonconductive tweezers is to avoid shorting the battery. Skin contact won't short it- but skin oils can lead to corrosion and shortened life. There are numerous tweezers with plastic or wood or phenolic tips that are appropriate, or finger cots as above and just get it in there.

I use the cots, even with high class tweezers batteries are surprisingly slippery!
