Replacement of the 10 year lithium back-up battery

To change the battery on your Night Owl Explorer NOCX3 monocular, you will need to follow these steps:

1. Unscrew the battery compartment cover located at the bottom of the monocular 1.
2. Remove the old battery from the compartment 1.
3. Insert a new 3-volt lithium battery (123 type), which is also known as the CR 123A, EL 123AP or DL 123A 1.
4. Screw the battery compartment cover back into place 1.

Please note that some models of Night Owl Explorer use 2 standard AA batteries instead of a 3-volt lithium battery 1.
I hope this helps you change the battery on your Night Owl Explorer NOCX3 monocular! Let me know if you have any other questions.

Please always refer to the user manual.

Sometimes places like Batteries + and the Battery Barn (on line web sites) will have replacement batteries for popular models even after the manufactures quit producing them. That is where I found batteries for my Bosch drill.

Lithium batteries have a limited lifespan, typically 3 or 4 years, and their capacity between charges decreases over the years.
To extend the lifetime of a battery it should be run completely flat after every few charges rather than topping it up. New batteries need to be charged several times and run flat under normal use before they gain their full capacity.

refer to manual -- but yes, i would say its battery issue -- replace batteries .
if you never replaced battry since you bought it and it is over 2 years old, then you have lithyium type battery .
if it came with lithium battery, take the screw(s) off-- mouse will have lithium battery (size of a quarter), then go to radio shack and buy replacement -- but have RADIO SHACK test your battery before you buy another one, to make sure it is a battery issue.

Hi gregbrands,

If your watch is several years old, I would recommend sending it back to Casio for service and battery replacement. Contrary to what you may hear about solar-powered watches, the rechargeable batteries do not always last for 10-20 years. I've seen some go out in 2-3 years. This is a shorter lifespan than most standard lithium watch batteries.

You may have an authorized Casio service center near you also. If not, contact Casio at the following numbers:

For Repair support in USA at 1-800-706-2534 during regular business hours (currently Monday-Friday 9:00a.m. - 5:00pm EST, Saturday / Sunday 10:00 a.m. - 8:00 p.m.) For Technical support in USA at 1-800-435-7732 during regular business hours (currently Monday-Friday 9:00 a.m. - 8:00pm EST for all products, Saturday / Sunday 10:00 a.m. - 8:00 p.m)

The cost of your watch well justifies this kind of service, plus, they will assure it remains waterproof up to its specifications.

Let me know if I can help further.

Thanks, Bill

Every PC motherboard has a battery. That battery serves two purposes: to feed the configuration memory (also called CMOS) and to feed the real time clock of the computer (the one that show the date and the time).

An indication it is time to change the motherboard battery is receiving one of the following error messages when you turn on your computer: CMOS CHECKSUM FAILURE, CMOS BATTERY STATE LOW, CMOS SYSTEM OPTIONS NOT SET and CMOS TIME AND DATE NOT SET. Another indicator of a low battery is a clock that, after being set, runs well while the computer is on, but shows the wrong time when the computer is turned on the following day (it is late).

The motherboard battery can be built using three different technologies: Nickel-cadmium (NiCd), NVRAM (Non-Volatile RAM) and Lithium (Li). The Lithium battery, which is a round one (the size of a coin) and can be easily found at watchmaker's and computer parts stores, has long been the most used type. To buy one of these batteries, all you have to do is to look for a model CR2032 one.

Replacing the motherboard lithium battery demands some care. It seems to be a simple task, but it is not.

The lithium battery may use basically three socket types: socket with upper tab (Figure 1), socket with lateral tab (Figure 2), and the socket into which the battery stands instead of lying (Figure 3).

Fig 1



Fig 2

While the replacement of the battery in the socket with the lateral tab or of the one that stands is simple (Figures 2 and 3) – all you have to do is draw back the tab using your finger or a small screwdriver and replace it – the replacement of the batter that has an upper tab covering it (Figure 1) demands extra care. In this type of socket, if you raise the metallic tab to replace the battery, it will lose its pressure and will not make contact with the battery anymore, damaging the socket. In this case, the correct replacement of the battery in done pressing a small plastic lock at the side of the socket with the fingers or using a small screwdriver. That will allow the battery "to slide" laterally, not damaging the upper tab.
Whatever the socket used, don't forget that the replacement of the battery should be done while the computer is off.
