CR123 mixup

[jjearl111]

I have 9 CR123 batteries and 3 of them are dead. I need a way to tell which ones they are. I have a battery tester and the settings are DCV OHM ACV 1.5 V 9 V 500U 10M 250M DCA and need to know which setting to use. Thank you

I don't know how to help you with this, but for future use I reccomend marking the cells.

Use your meter to check the voltage. If the 3 dead cells are really dead, they will stand out.

You want to use a volt/ohm meter set for DC volts. Your RED Lead will go to the positive terminal (the one that is raised) and the BLACK Lead will go to the negative terminal (the one that is smooth). If the battery doesn't read more than 2.7 or 2.8 volts DC or more, chunk it for safety's sake. Believe me, it just ain't worth the risk. If the battery is fully charged (NEW), it will read at least 3.0 volts DC or more. While you are at it, check all of your cells. If you are using your batteries in single cell lights, it's not that critical, but, if you are using them in lights requiring two or more cells, you should use only cells with voltages that are the same or as close to the same as possible in your lights. This is sometimes referred to as matching your sets. That's what Battery Junction does when they sell Titanium cells in sets of two and three and they don't do it just for giggles, either. This is serious stuff. It's really good that you are concerned enough to ask if you don't know. I'm sure there are more than a few who wished they would have asked before it was too late, as you did. KUDOs to you. :thumbsup:

If you use CR123's a lot try investing in a battery tester like the ZTS battery tester which tests a cell under load.

all the readings are the same for all the batteries, i dont want the ampiers, i want voltage, the cpu chip would mess up the readings

Where is Kamloops?

It's just down the road from Eneloops.

Moving this thread to the Batteries section, where it belongs...
