Fossil Kaleido Watch LI22248 replacement batteries???

The Li2248 is the original kaleido watch and takes a single flat round inexpensive CR2016 battery. It is worth replacing it as they usually last for many many years, unlike the newer Kaleido two watches that take two batteries that together only last about a year. Walmart will usually let you borrow their tool to remove the watch. This one is very easy to remove with the tool. Walmart will likely not remove it for you since they did not sell it to you but I have been to many Walmarts in many states to readily loan the tool for you to use at the counter. IT is a special adjustable wrench that will set in the indentations on the back of the watch and then rotate counterclockwise to unscrew the back off. Once inside, you do need a very tiny screwdriver to LOOSEN, do not remove, the screw that holds the bracket against the battery. Once the screw is lightly loosened the bracket slides out and away from the screw and you can then easily remover the old and place in the new battery. You then retighten the tiny screw and then screw the back of the watch back onto its case by hand at first and then with the watch tool to tighten it. There is little chance of damaging the watch or loosing your waterproofing if you can get access to the watch wrench.
I have just opened a blog site devoted to answering questions about Fossil and gametime sports watches especially the sport logo watches. The blog site is sport logo watches blog at http://sportlogowatches.storeblogs.com/ I am putting together a pictorial on how to replace the batteries in the Kaleido II watches but this is quite a bit more challenging than yours. Good Luck!

Depending on the age of the watch it could have a ECR series battery over the top of the 377 powering the movement or it could have 2 377's in the circuit board over 1 377 in the movement.

I always recommend taking Fossil watches to a certified repair shop that can re-seal the watch so you dont void your 12 year warranty and the watch remains water resistant and resistant to small particles.
