I have a wireless camera setup and each camera uses 4 CR123A batteries.  Every now and then the cameras will drop out of the system and a battery change gets things going again.  I was about to pitch the 4 old batteries but decided to put a meter on them.  One of the 4 was dead and the other 3 were at 70% or higher.  I've had similar experiences with other battery powered devices and one bad battery kills the device.  I wonder how many good batteries get pitched because of one bad one?  My $7 battery tester may prove to be a very good investment.

It doesn't have a 3.7v setting, so I guess not.

Have had similar experiences with various devices that use cells in series. One will be drained, the others might still be good.


In the 123 cell world, I've squeezed 3 lifetimes out of a set of SureFires

M3 (3 cells) pitched one when it went dim
E2D (2 cells) pitched a second when it went dim
E1B (1 cell) - useful for testing cells too

I read somewhere that you shouldn't mix used batteries and new batteries.

True?

I've done it on everything from TV remotes to class 8 trucks. If it's gotta run its gotta run.

Not saying its the proper thing to do though lol

You're "not supposed to mix" them to try to avoid uneven drain on the cells, which results in one being dead and the rest still good.

True. ESPECIALLY with primary lithium batteries like the CR123 and the Energizer Lithium AA L-91.



Bad things can happen. Like fires and/or exploding batteries.

Explain this comment. Aren't these lithium types protected cells?

I paid about $1.50 a piece for Streamlights on Amazon.

ETA - the added shipping doubles the price of the Cheap 123 deal unless you buy enough to get free shipping.
