LR44 BUTTON DOESN'T SEEM TO FIT battery case seems to be high and doesn't allow button to reach the test bar

I use a size 10 (yellow tab) battery which is 3.6 mm thick. It appears the LR44 battery is 5.2 mm thick. My tester works fine with my battery. Thickness of LR44 may be a problem. Be sure battery is in with the correct side down.

Remember that the + side faces up which means the whole side of the battery is the positive terminal. The negative side faces down and from the looks of the battery case that button is very thin so with the button down on the plate, the test bar should easily contact the case.

It's easier than you think. The compartment below is for spare battery storage. To test simply lay the battery face down on tester. Hope this helps.

I had this problem a few times. The position in which it works is very specific. Carefully put the battery in and male sure all corners are in. Then put the rest of the case on before you try it. That's what works for me, hope it helps

Not sure....there's 2 round button slots or testers. One for a 3V and one for a 1.5V. I have not used either of those.

I am sorry to report that something must have changed with production since June of 2013. I performed the exact same test that V.Bolinder did, and mine is dead. I opened it to see if, as others have mentioned, the panel was not attached. Oddly enough, it is soldered onto the board just fine. IN my opinion, the battery is not a rechargeable button cell. I am going to purchase some rechargeables of this size and replace, see if that works.

Yeah I do think the connector is a little too small to connect to the battery. I just spliced a new connector that was large enough to fit around the battery terminal. If you do not have any you can buy them at Walmart for a few dollars.

I'd make sure the battery was in correctly. It may just be a faulty fit bit and need to be returned.

mine also failed, though i eventually got it to work again by fiddling with the battery case. specifically i opened the battery slot, made sure it sat evenly in the case, then slotted it back in again. try pushing the case forward even if it looks like it already in. best of luck

There should be a switch and the settings marked on the side of the battery enclosure. You have to look closely to see the settings.

I had no problem...try rearranging the battery and wire to get the best fit...

Just insert your thumb and middle finger on each side of the battery slide and simply pull it out. There should be very little resistance. If it doesn't come out it could be sign that the battery has leaked and has caused the battery holder to be corroded in place. If that is the case, you will probably need a pair of pliers to free it. Then clean the contacts and install new batteries.

Looking at it as it is pictured (yellow button on the right) there is a small black tab sticking out from the bottom side of the read out. Push that tab up through the readout, the large slider should push out the topside. Pull it all the way out. Put the battery in + side down. Then put it back together. I hope this helps.

I do have problem in getting battery door to close. Not sure I'm doing wrong and it's a defect one.

Look at base end, there should be a model number. Are you sure it's not the battery. Buy the same model number.

Pushing the button on the battery case is how mine turns on and off. Possibly try changing the batteries? Not sure what size it takes though.

Turn off ignition make sure there is no load or disconnect Neg- Terminal, then Just connect to the battery and press the test button. I did not like this tester and returned it. Midtronics is the best in category

The battery can be replaced by unscrewing the top(flashlight) counter clockwise until it comes off the stick. Look at the top of the stick, not the light and you will see a standard LR44 button battery. I use a dental pick to flick the battery out. Replace and screw the flashlight head back on the stick.
