AAA battery and low voltage

zillah · 04-02-2009, 10:10 PM

I have got AAA batteries (non-rechargeable) that were used in a TV remote controller , when I checked the voltage for both batteries , device was reading 1.4 ,,,,,,,,,,,,Is that considered low voltage (do we need to replace batteries) ?

At which value battery would be considered as low voltage ?

I would say when your remote won't turn on or whatever... Like when its dead. that is when you change batteries

1.4v is not considered low, but the voltage is not the only consideration. It's ability to PROVIDE that V under load, ie: it's current delivery is something else.

The LEDs on a remote pull very little current, and depending on how many there are in the remote, maybe 100 - 150ma.

However, you cant test this with your meter. I mean, you could but it would essentially be a dead short and significantly drain those batteries. So don't do that. AAA batteries have very little umph.

The real test is as stated, does the remote work at a reasonable distance, or at all.
