My tester keeps shutting of on me when I go to test 18650's 3000Ah 3.7 volt Li-ion. Put new batteries in the tester, same thing. Anyone else have this

The old version of Mini-MBT cannot test 18650 hence most likely it is shutting down to protect itself. The new version has test probe for 18650. So you probably got an older version. It is confusing as ZTS releases new version of the tester but still labling it same model/version.

Sorry, but mine has successfully tested them. I'm sure you have tried all the clean the contact type stuff but if not I have seen where the tester is sensitive to that.

I do not see any markings for testing a 3.7 Li-ion volt battery on the unit, perhaps you're exceeding the voltage limits of the unit or maybe that's too many Ah (AMPs) for the unit. I suspect that it's shutting down to protect its self? My ZTS tester has worked flawlessy since i've purchased it, over a year ago. As always, consult the manufacturer for the final answer on the product they have designed.

Same problem with aircraft batteries. I tried setting it at a low CCA battery setting to see what would happen and got a reading. I have no way to know if that result is accurate. The thing is designed around inputting the CCA to do the test, so I guess it might not be the answer for you. You might want to consider a carbon pile style tester.

I have just cause I had them from another light that I killed and it didn't seem to make a difference. I keep 18650s in mine just because of how much I use it around the house. Just bear in mind that it is NOT 1000 lumen by a longshot.

The Nitecore charger is actually a great charger, it just sounds like you got a unit that was bad. As far batteries, the research I've done suggests that a lot of them are actually the same - just branded with whatever company is selling them. I'm not sure if they sell on Amazon, but I have had excellent service with a place called Orbtronic. The Orbtronic batteries work very well and I've never had a problem with them not charging fully. I also have a couple of EagleTac branded batteries for my EagleTac flashlight. I honestly can not tell a difference.

I haven't had a chance to test the tester out. There are sites on the internet you can check on and I tried to find some instructions on this - sorry.

Not sure but sounds like you have a shorted switch, I would email Streemlight and get it sent off for testing and repair, constant full discharge might ruin new battery.

Make sure its fully charged. I only figures this out after testing it out and seeing very short videos of the test. I know there has been some complaints of malfunctioning, but mine works fine.

I have the same issues! I have had great success with the 750ma (green) batteries, so I ordered some of these 900ma (blue) batteries hoping for longer life. Instead I got varying voltages, higher than 3.0V that the flashlight did not like, plus, they are slightly bulkier and get stuck in the flashlight. They should be built to the same standard, but they are Not!

I would immediately send it back. It has to be defective. My two batteries work just fine. They take the charge and hold it until you are ready to use them. Sorry to hear you had trouble. These are hi-tech units and I do suppose that they are a little temperamental.

Had my charger plugged in for a few days with a battery from a recently purchased yard sale 18-volt drill. The unit was warm to the touch, but not hot. I have charged other batteries and they were warm when removed. The charger changes to a solid light when the battery is charged, and I usually remove it at that time. If it's getting really warm, I'd try a different battery if possible. If same result, then I would contact vendor or B&D; as a warranty issue.

My charger came broken as well. I ordered this TangsFire® 2pcs 18650 3600 mAh 3.7V Li-ion Rechargeable Battery and 18650 charger from amazon, and haven't had any problems with it. I would avoid buying the charger sold by this company.

I had the same problem with the one I ordered so I opened up the battery case to see if maybe the betteries were bad or missing. They has become badly oxidied in the case and so were obviously very old. I pried the suckers out with a screw driver, threw them away (being careful not to touch them with skin in case they were leaking any fluids), cleaned the inside with a clorox wipe, and popped some new batteries in and it has worked great ever since. Give that a try and I hope this helps!

I've had difficulty with this issue, too. I think the battery tester works most accurately by just letting the battery rest.

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

www.q3i.com/support I dont know what is on this site but it is what was recommended in the box. The unit will stay calib. for over 200 tests however. I used to calibrate a lesser version of tester, and this one is much more stable. I do not expect to have any problem for years. Just check that the batteries dont go bad and leak. Cal is prob. expensive. there is a way to set up a standard vapor stream at .1 BAC just to check it yourself, but I have not had to question this yet as I dont use often. contact me at drj@bodymindspirit.ws and I'll keep you in mind when I do this procedure. www.q3i.com/support I dont know what is on this site but it is what was recommended in the box.

It might be that the charger died. I have had that happen. They don't last all that long. About as twice as long as the batteries in my experience. Do you have another charger to test them in. Maybe a friend has one.
