If I need a battery tester, I might consider this one from La Crosse. But, I don’t need a battery tester, or at least I don’t think I do.
A few weeks ago, my cousin mentioned wanting to get a battery tester for her parents, because they always have loose batteries around, and she could never tell which are good and which aren’t. Her mom was there, and disagreed, saying they don’t need a tester.
I have batteries in various places, and all but a couple are fresh and have never been used. There are times when I remove partially-depleted batteries from a device, but for the most part I don’t keep anything other than fresh batteries around.
The tester shown above can test AAA, AA, C, D, and 9V batteries. It basically checks their voltage and then moves the needle to red, yellow, or green, depending on the voltage, which is an indicator of a disposable battery’s charge status.
Testers like this are often calibrated for alkaline batteries, which have a nominal voltage of 1.5V per cell. Rechargeable NiMH batteries have a nominal voltage of 1.2V per cell.
I use Storacell battery holders ($4 and up at Amazon) when on-the-go. Fresh batteries are stored button-side up, and depleted batteries go back in button-side down until I can charge or dispose of them.
I remember using my father’s battery tester, and my grandfather had one in his kitchen utility cart.
I only recall testing maybe one sets of batteries in the past 20 years or so, and that was with a standard digital multimeter. I don’t own a battery tester; I have never bought one, and don’t plan to.
But, that’s just me.
I can see potential uses for one, such as in determining if there are issues with a device or if the batteries just need replacing. But even in those cases, a fresh set of batteries will either get things going, or they won’t, in case of a device failure.
Do you use a battery tester? Do you feel you need one?
Do you use a different battery tester you could recommend?
