Have the batteries been tested?

Not sure how to test them. Two came with the purchase but, my old regular batteries would last all day.

I don't see a date on either the package or the batteries, but they are working for me.

It's been two months since I purchased them and I haven't replaced the batteries yet.

Try them in multiple devices to make sure it's the batteries I have had zero issues with the batteries. Also make sure that there is no corrosion from anyou old batteries on the contacts.

I had to. However I think the new ones are made so the battery can be replaced. I would check.

You can check voltage , but u can't do a load test to confirm battery condition !

In my opinion this tester give an accurate gauge of the condition of the battery, I have rechargeable batteries that have shown up as good on another tester but under load were no use, this one weeds them out

Sorry but I never "tested" it without batteries. The display shows both readings which stay lit for a few seconds-I would think battery drain is minimal.

Not sure, but I have had the same batteries in it with intermittent use for months.

The only possibility I can think of is that the installed batteries may not have been very fresh. The manufacturer suggests testing the units and replacing the batteries yearly anyway, I believe.

My batteries are working fine and they have been installed for about 3 months. The electronics appear to remain off until activated by a finger print scan or entering the security code. Thus no apparent battery usage.

Sorry, haven't a clue. I've not even tried mine, just wanted something to test batteries before purchasing them unnecessarily.

I have not noticed that problem. They don't last quite as long as Panny's batteries, but the indicator does seem to be accurate.

I haven't changed batteries in mine yet, light to moderate use over several months. They have worked flawlessly so far.

No its not a tester. Yes you can charge batteries not fully discharged. Also, it will tell you if a battery is bad. However I've had it say this and with a rub of the battery against my clothes. The contract must have been better because then it changed fine.

Yes they do! with a little activation strip, so you can be confident that the battery isn't used or worn out.
