Some watches are powered by not one but two batteries, and when changing the batteries,
it's important to make sure that both batteries actually need to be changed. Learn how to
change double battery watches with this guide from Esslinger-.com.
The tools you'll need are: A non-magnetic tweezers
A plastic tweezers A watch battery tester
And finger cots
Before starting to change a watch battery, you will first need to open the watch case
back. To do this you may also need to remove the watch band. For help with these things,
click on the links.
Put plastic finger cots on your fingers that may touch the watch movement. Dirt, oils and
grease on your fingers can damage the inner workings of the watch and the cot will keep
that oil from transferring to the watch.
While you should find the watch battery numbers before you try to remove it from the watch
case, the large latch strap that holds the batteries in place will prevent you from doing
so. Be sure to remove the old batteries with caution so you do not lose them and find it
impossible to replace the batteries.
Find where the strap locks into place. It will most likely be between the two batteries.
There will be a small opening in the piece that holds the latch down like this one.
Take your non-magnetic tweezers and grip the metal latch piece showing in the latch opening.
Then, carefully push the metal latch down with your tweezers before pulling them out
toward you to release the metal latch.
Now that the strap is open, you can remove the batteries. With your plastic tweezers
and grip one battery to remove it. You may need your non magnetic tweezers to slip the
battery out of its slot before you can remove it completely.
Before removing the second battery, make a note of the replacement number on the first
battery.
Next, you will need to test the first battery to make sure that it actually needs to be
changed. For help on testing your watch battery, check out this link.
When you have determined whether or not the first battery needs to be replaced, set it
aside and remove your second battery with the plastic tweezers.
Make note of the replacement number of the second battery as well and be sure to test
it like you did the first battery. Again, for help testing a watch battery check out
this article.
Once you know if the batteries need to be changed, you can get the necessary replacement
batteries.
Grab the first new battery with your plastic tweezers, make sure that the positive side
facing up.
Lift up the battery strap so you can insert the first new battery into the battery compartment.
You may need to push it into place with your fingers so it fits just right.
Now that the first battery is in place, pick up the second new battery with your plastic
tweezers, again with the positive side facing up.
Lift the battery strap up again and insert the second battery into the other battery
compartment. Push it into place with your fingers if necessary.
When both batteries are in place again you are ready to close the strap over them again.
Take your non-magnetic tweezers again and grip the tab of the latch strap that locks
into place in the movement.
Holding the movement steady and in place with your free hand, reverse what you did to remove
the latch --push it down and then back toward the batteries until it slips into place.
Once the latch strap is back in place, you need to restart the movement. Use your non-magnetic
tweezers and put one pointed tip in the hole marked as a negative charge.
Place the other tip of your tweezers in the AC port in the movement. Once both tips of
the tweezers are in contact with the movement ports your watch should be running again.
When you are sure the watch is working again, close the watch case so you can continue wearing
it. For help closing your watch case, check out this link.
Be sure to properly dispose of the old batteries when you are done. For information about recycling
