I am not sure it's working right. The dead batteries and the good ones both show all the black bars. What is the proper way to use this?

Dead batteries should not show any bars; good ones should. Are you sure the batteries are dead? I had some I thought were bad, but it turned out that the battery contacts inside the hearing aid had gotten bent down; I gently straightened them a little and the batteries I thought were bad worked.

This type of tester came with my hearing aids. After a year it didn't work so well. I replaced it with one of a different type that I got from Amazon. As previous answers have stated, any dropoff indicates that the batteries are going out and won't last a day in.

I use this hearing aid battery to save battery when I´m in my work or another place. Sometimes I use this hearing aid battery to sse the level energy of battery. This help so much very well.

I too noticed this in the beginning. The best way I believe to test is to hold the battery in testing position for around 10 seconds . If it is a dead battery it will start showing weaker signals within after 2-3 seconds. Never go with the initial reading as soon as you place the battery. Hope this helps.

Insert battery with the small end down and push forward and the if the screen turns black it is good and you can take your reading

The battery case (the tab side which is positive) should be up and the negative (smaller) side should be slid on the gold colored bottom of the tester to the (paper clip looking) side. On first contact 100% would be great. It's not unusual to get get lower readings. More than 80% should be fine. Don't test if the hearing aid has a warning feature for low batteries.

Hold the battery firmly in place for more then a couple of seconds these batteries recharge a bit from non use so they may show a higher charge but in 4-5 secs it will drop rapidly. For my wifes hearing aid I only use the very good ones as almost any drop off is noticable (some could probably operate on less)

I found this product to be of no value for me. The reason is that I learned that hearing aids today need the full battery capacity and once it drops they shut down fast. I was told teds. hat this characteristics of zero/one is to assure better and continuous hearing signal. Therefore no simple and cheap measuring device can predict this. However as an holder for two batteries for the way to be available replacement it is good. Hope this assist.

I have the same thing happen to me. I think that it is junk except for having some gadget on a chain to carry an extra pair of batteries around.

Doito, went dead, no LED light indicates to me that your batter is nolonger connected, Check to make sure it has not disconnected, make sure it's not bad. Even new batteries are bad out of the box. I experienced this first hand as an electronics tech

The light on top was alternating red/green. I thought it might mean the batteries, but I checked & they are fully charged.Now, I can't get it to work at all, no lights, no pump, nothing...yes, the batteries are installed correctly. Any ideas?

Check to see if the batteries are lose. If it still does not work.......i suggest buying a new one.

Mine is still working well. But you can check if the batteries are in good shape or try to remove and replace the leds and batteries. I hope that helps.

Try moving it to the 6v selection. Providing the battery is charged, it should show in the yellow (60-70%) mark if it is good. If not, toss it.

I had the same problem. You have to use the wire connection along with the two batteries in the handle. Mine worked well after that. Enjoy !

maybe, your software/firmware might need refresh and or update, if still not working after that then yup it's probably dead...(might try new fresh batteries too....)

I had the same problem with my initial order of this item; therefore I requested an exchanged and once again the item was not functioning. I suppose to light up once the batteries are installed. Unfortunately, I finally requested a full refund. I think it's probably due to their shipping method (soft packaging via USPS) which can damage the interior components.

Mine works great and always has. The fact that a display cycles probably means that you have it hooked up wrong. In normal operation, one bar stays lit or flashes when low. Remember that the positive and negative have to ALWAYS be hooked up to your battery pos. and neg. I've got a switch on mine to turn off the display but it's not really needed. One user says "The C is for your switch to turn on the indicator, with my application, I ran a wire and connected it directly with the positive terminal for the indicator, beings I want to be able to kill power to the entire indicator when not in use. Prolly wasn't needed but that was my choice and it works great. The R is unused and I think I read that it's not commonly used." On mine, I think that means that when I installed it I hooked pos to battery pos and neg to battery neg. Then I hooked a wire from C to my switch and back from the positive pole on my switch to neg on the indicator. If you don't put in a switch, then I believe C just gets hooked straight to positive so that the unit will display.

Hello Brian, The instruction should be on the back of the black box. Please remove the plastics on the battery terminal before using the battery. Thank you

Contact the company, obviously it's something wrong with the bob it itself. why did you have to change the batteries on a new one anyway? The batteries should have been good. I would think something was defective if it didn't work in the first place. Contact the company.

It must be broken - if you put new batteries in, should work. Contact seller.

I would send it back. I have had mine for some time and have had no issues with mine. Sounds like a bad light sensor. Good luck.

You might want to check to see if you put the batteries in the right way. I made that mistake. The pictures aren't that clear which way you put them in. Good Luck-it works great once you get it going.

Same problem here! After I opened the box I charged the battery till the light turned green. Put the battery in the camera, put the film pack in, the black film cover came out (so I assume I put the film in right), turned the camera on but all the symbols are blinking and I'm not able to make a picture. After reading here I put the battery again in the charger and now the light turns orange!! But I just took it out because it was green?!?! Now I'm just gonna wait till it's green again and see if it will work. Does anyone have any others tips for me?XO
