How Do I Change the Battery on My Powerball Counter?

Troubleshooting the issue: If you have had your Powerball for a long time, you may have one of our original models with the SM01 counter. This counter is battery-operated and the battery may go dead at some point. You will know the counter battery is exhausted if the display is no longer working.

Solution: Remove the counter from the ball, remove the 6 small screws on the rear board and replace the two batteries.

Battery replacement step-by-step guide: 

Step 1: Please remove the counter from the top of the ball.

Removing the counter ican be done using either your finger nail, a small flat headed screw driver or knife blade (exercise care while using either tool!). The counter is anchored to the ball at the 12 o’clock and 6 o’clock positions by two plastic tabs (these are molded to the body of the counter). Please insert the tool/nail under the counter body at either of these points and lift upward with a quick, firm action – the counter should pop off.

The counter on your Powerball is designed to power down automatically if rotor rotation hasn’t been detected for a period exceeding 40 seconds. This feature gives the batteries an expected lifespan of 3-4 years of normal [Powerball] use.

In the event that one or both batteries are exhausted however, changing them is actually quite an easy task.

Step 2: On the back of the counter (the circuit board side) you’ll notice 6 small screws (as illustrated in Fig.B)

You will need to obtain a tiny star (Philips) screwdriver and remove these ( Fig.C)

Step 3: The circuit board will now come away from the counter body (Fig.E)

You’ll see the two small batteries (GP377 if your counter is grey in colour / GP392 if the counter is white). If you have a voltage meter, conduct a test – the voltage should read between 1.4 and 1.59 on each cell – any lower and there is a risk that the display will begin to fade. These batteries are easily found online or in an office equipment store.

Replace and reinstall the screws and pop the counter back into the Powerball shell.
