Rechargable Batteries ?

[moose57]

Tenergy Batteries has rechargeable 9 volt batteries that are NiMH at 200 and 250.I
don't really know what these numbers mean.Should a person check with Tesoro
first before getting rechargeable batteries for the Elarado,and the Golden umax,&
the Tejon first before buying the batteries..

I have been using EBL brand 9v 600 mAh Lithium-ion rechargeable batteries in my Tesoros for some time now. They work just fine. I purchased them on ebay.

 

[Welgund]

I use the tenergy 250mAH for my tesoros, they fit 8n the battery slot great and have decent life. How did you get the ebl 600mah to fit in your tesoros? They are too tight in mine and can't put the battery covers on.

strangely enough after a lot of testing I have settled on the soshine Ni-Mh 9V battery the black ones have the 9.6 & white 9 volt...they have the best shelf life as in holding a charge the longest of all the Ni-Mh battery's I have tried.

sure the Li Ions will hold longer but they don't get the volts.

but as always remember there is many brands and that's for a reason we all have differing needs.

I do like the 9V better than AA battery's for one I only need one, and they can be charged to the same volts as a primary cell, and AA battery's get mixed up and then a flat one can get in with new ones and rechargeables don't come up as high as primary's and yet detector company's continue to use AA battery's .

only detector I own still running on AA battery's is the gold racer the others that do have been moded to run 18650's long run time short charge time etc I might go a duel fuel on the racer and just make a 5 AA pack, see how I go...

but really 9volts are good for me but really all detectors need a li ion pack long run time short charge time.

and I sure wasn't planning to write so much but it just came out so I run with it

I remember a past post where the Compadre was the only one where the 9.6 should NOT be used because of the initial voltage spike.

 

[slingshot]

As a followup, I forgot to mention I used the Tenergy in my Compadre with 10 hours usage. It's the 9.6 higher voltage that could be damaging.

I'm of the opinion that rechargeables are not worth the effort. Battery drain on Tesoro's is so slight (especially on the single battery models) that they just don't make sense to me.

 

[JEF]

I haven't had any problems with the EBL rechargeable 9v batteries not fitting. I have them in all of my Tesoros. You do have to press down on them a little bit when putting the battery cover on. They last quite a while before needing to be recharged. I carry an extra one with me in case I need to change the battery in the field. Then I charge it when I get home. I haven't had to buy batteries in a long time. I did have one battery that quit working (it wouldn't charge back up), but that was the only one. I bought eight of them with a charger on ebay.

I have the EBL 9v as well. They do fit like JEF said, but need a little help while closing the door. Same help needed for my alkalines. Duracell seem to be the smallest and tied with the Tesoro supplied Panasonic's (which I'm told Panasonic makes Duracell cells for them.

I did pick up an 8 pack of Duracell's off Amazon for like $14 because of how my vaquero acts with the rechargeables. No performance loss but only has 4 beeps on freshly charged batteries.
I use my EBL cells in a couple detectors and my bandido II micromax has obviously used taller cells too because the battery prongs are smushed back pretty far and I need a folded paper wedge for Duracell's to fit without losing contact.

I did buy the ebls for using and plan on doing more testing this season with them, but u couldn't pass up the price on Amazon for the Duracell's.

Some have said they received Chinese ones which is where the review from Duracell came from.
The ones I received looked identical to store bought and they were cheap.

Now for my AA machines I've been very vocal on my love for Panasonic eneloops. They are fantastic!!
My Deleon does read 2 bars less than full on a new set but I easily can get 30 hours on them. I haven't tried really, I just carry a spare set, when I get home I top off the ones I used and next outing use spare set and have the first ones as backup.
I've hunted 3 4-5 hour days on them without charging and the bars never move.

Rechargeables will register lower at the start but they stay there for a very long time, then drop off quite fast.

 

[vlad]

others don't-but most have a +/- tolerance to operate in, so slight voltage variance is no [major] problem.
I know the TDi Pro has a stronger battery-than other versions of the unit, and people get after-market battery setups
for them at higher voltage because they have enhanced performance. With some of the other versions, while the battery still operates
the detector, performance is down on the last few hours of use-but the P.I unit is a high power with a lot of drain.
My older Tek Mk-1 has the modified battery set up using 9 volts + AA packs to replace the original 14 AA pack. It works ok, but does not last as long.
I use the high mAh NiMH batteries (Amazon has great prices) except 9 volt-just do not have enough time per charge in my CZ.
(Troy told me they did not last as long in the Shadow either) Cannot recall for sure, but it seems the Sovereign rechargable pack for 1.2 volts had more cells for the lower voltage.

This was in the factory rechargeable pack in order to get the 12 volts needed. Some tried using 8 of the rechargeable in the alkaline packs and said they worked, but I had seen many complaining on not lasting as long and the low battery alert coming on with in a few minutes and some longer. On the rechargeable 9 volts for my Tesoros and my Uni Probe headphones I just didn't have any luck with them myself as the voltage was too low (7.2 volts) on the ones I tried, but that was a few years ago. The Uni Probe would not settle down and hard to know if it see a targets as it looks like it needs the full 9 volts to work correctly.

Vaquero? I was putting a new battery in every third or fourth outing.

 

[Sonnyd]

I have rechargeables for my AA machines but not my Vaquero.. I'm at about 20 hours now on the Battery that came with my Vaquero, and I'm still getting all the beeps just like I did when it was installed. It seems to be Awesome on battery life..

 

[Stoof-tabsallday]

Yeah. I have some EBL 9volts but they are a bit big, so I use them in my pinpointer. But I picked up some Duracell's on Amazon for a good price. About 1.80 each.
I figure they will last long enough.
The beauty of tesoros is that they really don't eat the 9v that fast.
And the AA machines I have love my rechargeables. Just wish they found a way to make Duracell size 9v rechargeables lol

On most of my detectors this could be say Whites,Tesoro and other brands that use AA for the most part the battery longevity these days is pretty amazing,so basically use top of the range Energizer alkaline batteries and always carry abundance of them in my detector case.

Dont tend to use rechargeable AA batteries on say the Vaquero that i use,although a normal Vaquero runs a single 9v battery,mine is the Laser Trident11 Extreme aimed at the UK market which uses the Tejon battery box hence 8x1.5v over the normal 9v,and that still lasts many outings,so still use alkaline batteries.

Then we get onto my a couple of Whites machines,the TDI Pro uses a 14.4 volt pack as usually Pulse machines suck power at a greater amount over normal VLF machines,i can run the TDI when fully charged all day long,but always carry a spare one in my truck just incase,they are not cheap batteries but should many many years if looked after.I do run a RNB battery pack in my Whites VLF machines ie DFX,MXT and IDX Pro as they use the same battery pack,this option you charge up and it just keeps going,longest run time with the RNB pack has been well over 50 hours in the IDX Pro and it still had some power left over,wish i could say the same about both my Nexus machines.

Then we get onto both of my Nexus machines the slightly older standard SE dual 9'' coil and the latest Nexus MP,the SE i can get just over a days use before the batteries finally fold,but that can run either alkaline or rechargeable ones,but the battery hungry beast is the MP,this runs 10 AA batteries and can run upto 16v so 10x1.5v alkaline batteries do work,but when running full power as the voltage to the coil can be increased by a massive amount over a normal VLF machine,you gain massive depths but at the mercy of caning the batteries,when using the detector for deep detecting on say pasture for relics/hoard hunting you can/could get through 2 sets of batteries in a day,so alkaline batteries are out because of the cost but Eneloop 2700mah one are certainly in,cannot praise these enough,superb battery run time,i will agree they are not cheap but in the long run they certainly are.Am lucky that that both Nexus machines have onboard chargers as well,so run a small inverter in the back of my truck so that i can top both machines if need too while having a couple of 'bacon rolls' and a cup of 'Darjeeling tea' at break time

Was lucky that within this last month a local large shop closed for a total refit,and right at the back of the store they had huge amounts of AA and AAA Energizer rechargeable batteries all market up wrong to get rid of the stock,i bought everyone of them,not my problem they got the price wrong,but a bargain like that could not be missed.

But for me Eneloops are my 1st choice as they do last a fair amount of time,then my 2nd favourite option is the Energizer ones,you can find higher capacity AA batteries on Ebay but these are often el-cheapo inferior copies and also far lower rating than what they are supposed too be,they may be cheaper but in the long run are not a wise option,buy cheap buy twice comes to mind.

 

[Stoof-tabsallday]

Energizer does make power plus 2400s. Duracell ion core new ones are 2500. Eneloops have pro version that's 2550, EBL has 2800mah (tested true but don't know about how many recharges), even rayovac has recharge plus at 2400 mAh.

But in the end, the regular (normally white but come in other colors as special editions but not black, those are the pro HC ones) eneloops are great. Good balance of capacity and holding charge unused.
The higher the capacity the quicker they discharge on the shelf. But that's relevant. The newest batteries today lose way less charge than anything in the past.
But as an example, the white eneloops and the black both charged to full, let sit for 2-3 months...
When discharge tested the whites (1900 rated) held onto 1750-1800mah where the black (2550 rated) fell to 2100. The eneloop pros are the best as far as holding their charge compared to the other high capacity batteries, but for the cost I like the regular 1900 version.
After sitting the HC are only 200 ish more mah than the whites after same time.

Now if you're using them in flashes as a photographer, most definitely get the pros, but for our use, the regulars are great. And cheaper.
Now what to do with the other 100 batteries I have from other brands I bought for testing..... Haha

I just bought 8 Eneloop Pro's. I also bought 4 of the Energizer I think 2500's or 2450's. It didn't take long for the Energizers to loose one bar in my AT Pro, but never dropped less then that after 5 or 6 hours. The Eneloop Pro's I installed yesterday in the same machine, was still running all the bars after 3 hours. I've heard it takes some of these rechargeables a few charging sequences to come up to full rating. I doubt I will get a rechargeable for my Vaquero since it gets such great life out of the regular 9volt (still on my original) Tesoro, and still getting full beeps, even after 12-15 hours now. And my Garrett Pinpointer is still fine on a Duracell after I have no idea how many hours...Stefan you are right, the Eneloop Pro's are probably not needed, as the regular white ones would probably be fine. I like the fact that they only lose 15% charge in 1 year....

 

[Stoof-tabsallday]

Well my testing shows more loss than that, but it's still head over heels better than older ones.
I only recommended the white eneloops because of the cost.
And the Energizer's are good too. They have universal (2000mah) and power plus (2400 mAh) and they were good enough. But I can't find anything to beat eneloops.
Even my white ones average 2100mah.
But they are definitely worth it in AA machines. I have many, but if you have enough to run your machine and also backup set then you're good. But even one set is enough because they won't die fast at all. On my Deleon new charged set shows 1 or 2 bars missing but it never moves from there. Even after 15-20 hours. That's the nature of them. They read lower than alkaline, but stay at the 1.3 v forever. Alkalines start at around 1.5 and constantly go down. Rechargeables start at 1.4 and drop to 1.3-1.35 then stay there for the entire life of the battery, then abruptly die.
I'm glad they're working for you and any eneloops are good. Really any rechargeables that are not unknown are good. But eneloops are king.

I have a Dollar Tree nearby and I get 2 nine volts for $1. I just roll with that. Almost free

How long do they last compared to Duracell?
