AA Energizer Lithium Battery Question

---

I have 2 White’s Metal Detecters (TDI Beach Hunter & XLT). Both take the standard White’s 8 AA battery pack. I’m trying the new leak proof 1.5 volt AA Energizer Lithium Ion batteries, however the 8 pack reads 14.15 volts. (12 volts is the recommended voltage). I also heard that increasing the voltage increases the operating temperature of the batteries. Is the voltage of these batteries too high? Will they run too warm?
Thank you in advance for your feedback. Tt

Should be close enough. Most modern detectors have a voltage regulator internally to compensate for the slight voltage differences between battery manufactures and battery types. The drain on either battery should be the same, which is where the heat would be generated.

When you say it "reads" 14.15 volts I'm assuming you are using a volt meter to test them. Batteries with no load will usually read higher. Once you put them in your detector they will be under load and will read much lower (nominally around 12v) so you should be fine.

Thank you mts, good information. Thanks for the reply. Tt

Metal detectors don't draw enough current to cause the batteries to heat up enough to cause any problems.

Agree with everything that's been said. Please make sure you dispose of your Lithium batteries properly too.

We had a Lithium battery pack start a fire at work years ago, so we started the practice of taping both ends of all batteries before putting them into the recycling bin.

Definitely good advice. Same applies to standard 9v batteries. Anything that has terminals that are close together that can be easily shorted out should be taped before disposal.

We had a lady come to a metal detecting club meeting with an extra 9v battery in her purse for her detector. She shouted out that her purse was smoking. Turns out that 9v was being shorted out by her car keys and almost caught her purse on fire.

That won't stop lithium batteries from igniting if they are crushed or punctured.
