Changing the battery on a Halopulser is very simple. As you can see, if I turn my Halopulser on and I press the test button, the indicator light does not flash. This shows us that it's time to change the battery. The first step is to take off the lanyard, which you just unclip. The next step is to open the case.
And for this, you're just going to use a fine tip flathead screwdriver or something with a similar tip. And if we look at the case, there is a fine ridge that runs around the midline of the case. To pry it open, we're going to take our flathead screwdriver and put it into this ridge at the protuberance for the lanyard.
We're just going to put that in and pry until it pops. Then we take the screwdriver and wedge it in just a little farther until the case pops open. And you'll see it comes apart with no problems. The circuit board and the case are not attached. So, it simply pulls out, like so. And now you can clearly see the silver battery holder, and the CR2032 battery.
To push this out, we take our screwdriver, and we just push from the side, like so. You'll see the battery will start to pop out, and you can just pull it out. We replace it with the same type of battery, which is a CR2032 watch battery, and you'll see at the top of the battery holder there is a plus for positive, and a plus for positive on the top of the battery.
We simply slide the battery in with the pluses facing up, like that, and the battery is inserted. We can test this before putting it back in the case, by toggling the unit on normally, and pushing down on the little white button here, which is the test button, and you'll see the LED light up. So, this is good to go.
To put the unit back together, we simply reverse the process. You'll see at the top of the board, there are two notches, which key up. With two protuberances at the top of the case. We simply slide the board in, push it down to seat it, and then we take the top of the case, put it over the top, and click it in.
And there we go. We put the lanyard back on, and we test again. And as you can see, everything is working perfectly. That's it. It couldn't be simpler. But I have one word of parting advice. Don't be afraid if you find yourself going through batteries at different speeds. There's a lot of variables with batteries and battery manufacturers.
Some get discharged faster than others, and that can be for a lot of factors, such as how old the battery is, if it's been sitting in storage, your use, the time of year, the temperatures the battery's been stored at. But generally, for something like this Duracell battery, I'm getting over 650 hours out of my unit.
This battery was in my unit for well over a month, and I used it every day with no issues. So, your mileage may vary, but don't be alarmed if you find yourself going through batteries at different speeds. As long as the unit is lighting up, you're getting that pulse, and everything is fine. I hope this tutorial has been helpful.
If you have any additional questions about your Halopulser unit, please don't hesitate to let us know.
