BATTERIES??

[basstrackerman]

if my rechargable batteries are only giving me 1.2 volts each fully charged am i going to lose proformance with my tejon?? all of my energizer non-rechargable batteries are at 1.5 volts each.i will lose 2.4 volts with the 8 batteries total over non- rechargables. that dont sound good. i know it wont hurt the electronics, but will it hurt depth? thanks alot

I've been wondering the same thing.
I use Rayovac and they read 1.63v when new. When I get down to 3 beeps they show 1.37v. I always feel like I might be losing depth when the machine gets to 3 beeps, but don't have any facts to back up that thought.

The detector has a voltage regulator. When the batteries run down to to point that they can't supply the minimum voltage(9v I'm guessing), depth will drop off and the battery test will fail. My experience with rechargeables is they provide enough power when charged but run down quicker than alkalines. I think the detector provide full depth as long as the test shows the batteries to be good.

I agree with that.

Rechargeable batteries would give a shorter life per charge comparing with alkaline, and certainly NO loss of depth.

IMO rechargeable nicads are NOT as good as alkalines, however the Nimh might be in the running for the AA class but NOT 9v.
Some 9v nicads may have a case that won't fit well in the Tesoro slot. (Mallory is at least .060 thicker than GE.)
I have no clue regarding lithium ion batteries.

However, I'm gonna try a flat pack from one of our RC toys, for entertainment. Just because we got a ton of 'em!
I'll just tape it under the rear of the shaft and run a wire to the control housing.

In disagreement with two posts above, I doubt if the voltage regulator is set to 9v, and also would not use the word "certainly" in regards to depth.

I suspect it is not only a voltage requirement, but also capability to deliver suitable current that may be a requisite, here.

Other factors being equal, a MD using a display in addition to audio would most likely consume more power.

I agree with you rmptr when you said - Other factors being equal, a MD using a display in addition to audio would most likely consume more power.

I know some detectors (White's Prizm) uses two 9 volt batteries, one drives the audio & one drives the display.

With the reasonable price of alkalines, I don't use rechargeables. A 9 volt alkaline battery in a Tesoro lasts a very long time. Steve.

The 9v was a guess. I don't know the actual voltage the regulator is set at but I would say it would have to be less than 12. I agree, that as the current increases the voltage will drop. I'm assuming the battery test on the detector checks the batteries under load. The issue I've had with rechargeables is that they will run down on the shelf and leave you with dead batteries at a bad time. One exception I've had to this is the powerex 9.6v rechargeable. But I still keep an alkaline in my pocket as a backup.

Hi

I use another brand of MD powered by two 9V batteries. I assure there is no loss of depth when using NiMh 9v rechargeables compared with alkaline. But a set of two alkaline will power the unit for 22-23 hrs. NiMh only 6-7 hours. This being said, it is true that things are different when it comes to AA batteries. They will last MUCH longer than alkaline AA's (Try that in a digital camera using AA's !!)

I started using panasonic oxyride AA's in my Deleon and have 20 plus hours on them, still have all bars.Cheap also--Kurt

hi all, there's just no question about it... energizers and duracells are the way to go. anything else is liable to let you down in the middle of a good hunt. there's nothing worse than that. it only takes one time. having good hot batteries has everything to do with increased depth and good overall performance. as a longtime hunter and a cibola owner, i would never even consider putting cheap dollarstore batteries in my machines. no time or room for cheap batteries here. your machine, and you, deserve no less than that. i understand that good progress has been made in rechargeable batteries, especially those from radio shack. but having been down that costly and unpredictable re-charge road, i'll stick with the energizers and duracells for now. just my two cents, fellas. hh,

I was lookin at some oddball rechargeable batteries today, in a discount excess store... Hmmm.

[chuck ky]

where do you purchase the oxyrides?

 

[kurt-ks]

Hi Chuck, Don't know if you have a Alco discount store? Thats where I buy mine.Maybe do a search for distributors?Personally I have tried allot of makes and models of AA batteries in RC cars,planes, and metal detectors,and talked with a lot of folks including dealers and those are the ONLY one's I will ever use, they have never let me down,which I might add, the bunny has died in the parks many times on me--Kurt

I screwed up, those were for AAA not AA batteries, sorry about that.

I'm sure it's been answered but the answer is no, they will work just fine, won't hurt your depth, and you will see over the long run are better on the Pocket Book!!

I'm with Kurt... the bunny has great commercials, but it seems I've done better with 'Neo' Anderson.

I'm back...

Bad penny and all that.

I charged up a pair of 1800mah Ni-Mh AA batteries overnight that have been rolling around in my desk drawer for a while.
This morning each of them was at 1.4 volts and my cheapo load tester rated them at 3.9ma.
A new alkaline AA shows 1.62volts and 44ma.

So that's probably not too bad...
But they are Ni-Mh, and NOT Nicad. Not a clue what I paid for 'em.
A pair of AA coppertops was 99c at the market, today, but I usually get 36 packs of 'em.
