Most of these resin-case F-series Casio sport watches use a fairly large lithium coin cell battery. Once the four screws holding the watch back are removed, you should be able to just pop off the stainless steel spring clip that holds the cell in place and pull it out, without having to remove any more screws. Be careful when replacing the clip, because it is asymmetrical and goes in only one way. Also be careful not to lose the tiny spring contact that connects the watch movement to the piezoelectric sound element glued to the watch back. If you lose the spring, the watch will still run, but the alarm won't sound anymore.

Yes you need to remove the 4 screws, an eyeglass repair kit works great, but take them out and you should see the battery. there will probably be 1 more screw to remove battery

Where i can replace the battery of my Casio watch,.Casio hunting timer AMW 705


The battery of my Casio 1846 W-71 was dead, so I tried to replace the battery by myself.

First, you need to get a hand on a CR2016 3-volts battery. It could cost you 5$ or 10$, but I got 5 of them for 1.50$ at an electronics discount store...

Get a precision screwdriver, remove the 4 screws. Be careful when you remove the cover, there's a tiny spring. Remember where it is, then remove it. Remove the watch from the shell.

Using a flat mini screwdriver, remove the cover that holds the battery. You'll need to unclip all 4 corners. There are centers to unclip too, not sure if there was 2 or 4 of them.

Remove the battery, place the new one. Clip the battery cover back, and put the watch back in the shell.

I closed the cover. The watch was showing time, buttons were working, but no sound at all. Looked on the Internet, and read that you need to short circuit it.

Look carefully, there is a label "AC" near a small hole. (Inside the hole you'll see the gray spike of a welding). Just touch something metal inside the hole (e.g. the welding spike) and then touch the positive (top) side of the battery. Put the cover back in place, press a button and listen for the beep.

Screw the cover back in place.

Casio not working


You need to Shortcut the battery with AC contact. AC can be found on the sides of watch movement(very tiny). You have to use pointed tweezers: one end on battery+, another on AC contact for three secs to get the watch started

Replace battery on Casio DB-36-1AV


Open the back (4 screws). Careful with the rubber seal and spring inside. Use a pin to pry the battery clip away from the bottom of the battery. You need to pry the bottom out and up. When the clip releases, the battery is easy to remove/replace.

Replacing the battery..


Ok Mdane

This is going to be tricky not have seen that watch before at all. BUT like most Casio's there screwed casebacks.
All you have to do is undo the 4 screws (usually) and take of the back gently remove the battery? Sometimes it has 2 small screws if you gently unwind one a few turns and the other take compleltely out and set aside. Remove the battery and take it your local battery shop (sorry from australia so I don't know where you get your batteries walmart perhaps?) and replace it in the reverse order. Sorry if its so vague I haven't seen that watch before
Hope it helps

Please help me to replace battery on my casio F-91W


This reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, similar to your F91-W. After the new lithium coil cell is installed and secured with the spring clip, the watch may show random segments in the LCD display or may simply be blank. Insert a sewing needle, paper clip, or blade of a small jeweler's screwdriver into the hole on the back of the movement stamped "AC" (All Clear) to momentarily connect the gold plated contact at the bottom of the hole to the stainless steel battery clip. The battery clip in most such Casio watches is connected to the "+" terminal of the coin cell. This will reset the CMOS chip and it should start up with the watch displaying 12:00 and the date at 1-1. Then, use the control buttons to set the time and date in the normal fashion.
