How is Your Battery?

Many of the devices and tools we purchase and use today are powered by batteries — from cell phones to computer tablets, cameras and remote controls to even most car keys. You name it, if it’s a small electronic device, it’s most likely powered by some type of battery. Some of these devices draw very little current (or power) from a battery while others draw considerably more. For example, it’s very common for a battery to work in a smoke detector or garage door remote for years. On the other hand, many hardware tools wear out batteries relatively quickly.

At Zircon’s customer service desk, most of the support calls we receive are StudSensor stud finder operational issues due to low batteries. Many StudSensor owners leave the battery in their tool when they’re stored away. Unfortunately, most nine volt alkaline batteries (as well as other types) do not hold their charge well when stored for long periods of time, even when stored in the original packaging.

The StudSensor™ e50 uses one 9-Volt battery. It quickly and easily locates the edges of wood and metal studs and joists behind walls, floors, and ceilings.

Since a Zircon stud finder draws a good deal of current from the battery power source, a robust fully charged nine volt battery (alkaline type) is essential for the tool’s operation. For example, when a battery is too weak to operate in a StudSensor, the tool will usually begin to flash and beep intermittently shortly after it’s powered on. Sometimes, the tool will look like it has calibrated (powered up) normally, but will not react to any density changes (find studs). On models with a LCD display screen, the screen may go blank after a few seconds. Many users think that these symptoms indicate a hardware failure, but that’s usually not the case.

That’s why using a brand new recently purchased battery with an extended expiration date is best. No matter what type of battery you need, remember to buy it from a large hardware, drug or grocery store. These big stores sell through large quantities of batteries. They don’t sit on the shelves for long, so you have a better chance of buying a strong fresh battery.

A good rule of thumb is: Always use a fresh new battery in your electronic tools. If you’re not going to use it for awhile, always store the tool without the battery installed. With a fully charged new battery installed in your Zircon StudSensor, or any other electronic tool, you’ll get peak performance and your best chance for a successful outcome to your project.

    unit sat for more than 2 years, but battery still measures over 9 volts! Will not calibrate and beeps continuously with all icons flashing. Also, I had undone the screw….sorry. Did I wreck it??

    • Hi Stan! Sorry for the delay. The good news is that you can usually get the stud finder working again after the screw in the back has been taken out. Take the battery cover off and take the screw out again, then lay the unit flat on a table. Carefully take the top half of the cover off revealing the circuit board inside. Make sure everything in there is aligned correctly and looks square. Check that the battery spacer (the little plastic part with two holes in it) is sitting in front of the battery contacts. The small hole is the “+” and the larger hole is: “-“. If everything looks good, place the top of the unit back on. There are two tabs at the very top of the case cover that have to go in first in order for the top to fit flush with the bottom case. Make sure all the seams are flush, then replace the screw. Insert a brand new battery to test it. Depress the Power button and hold. The green “TruCal” light should come on and nothing else. Test it on your wall, but be sure to use a brand new 9 V battery. The reason is although your battery still measures over 9 volts, due to its age and previous use, it still may not have enough voltage to sustain the current load stud finders put on it when it’s powered up. These tools take a lot more voltage to power than a remote control or smoke detector, for example, might require. We hope this helps!

        Thanks for the follow-up. I replaced the battery and it still just beeps and flashes continuously when activated, except if I put my other hand around the top, thunb and forefinger in ahorseshoe shape; it then beeps once and is then silent i.e., it detects the presence of my fingers there.
        Thoughts?? Thanks again
