I recently purchased these

Blackube AA Rechargeable Batteries Lithium 1500mAh Double A Battery with Micro USB Charge - 1.5Hours Charging -1.5V/2250mWh - 4Pack

They are the proper 1.5 volt and lithium batteries. They work well in my Tesoro that tends to chew up batteries fairly quickly. Will see how they hold up. They should not fade in performance as regular Alkalines do.

$20 for 4 is pretty good. Much less than the $80 I paid for my AT Pro lithium pack.

No question, just saying so far they are working well and about half the money the AA lithium rechargeables were not too long ago.

Keep us updated as to how they work. I'm curious as to their longevity given their relatively fast charge times.

Have a good 10-15 hours on the first charge on these batteries and they are still nearly full with no loss in power. Machine performance is like a fresh set of batteries. 

I am getting the same performance I get from my RnB pack I got for my AT pro at 1/4 the price.

Well it's been 4 months on these Blackube AA lithiums on my Tejon and loving them! I am getting double the battery life with full power till they are drained. I did have an issue with one battery not taking a charge and Blackube immediately shipped me a replacement, who knows it could have been beat up in the postal.

Anyone using these and relying on indicators on battery life might be thrown off though as they run at high power until they don't have any unlike traditional batteries that simply fade in power. Being lithiums they don't have a memory so if your going out for the day it doesn't hurt to top them off. They take about 2 hours to charge from fully drained.

Now if they made 9 volts that would be cool.

Can you charge these in series at one time? Ben nlce to hook a 12v pack up to a 12v charger, and charge them all at once. Or do they have a special charger socket? Oh...I see...they charge 4 at a time...nifty.

I wonder what the runtime is on the White's TDI detectors.  Typically you get about a day with alkalines or NiMH, and as you note, there is a continuous deterioration in voltage output as those discharge.

I have seen some that come with a charger, ones I picked up from Blackube have a usb cable with pigtail mini usb's coming off of it so you just plug them in. Each battery has a light on them so they are red until charged and newer models also have a green led indicating fully charged. They should do well in any device that uses standard alkalines. I think they will do better in cold weather as lithiums don't lose as much power as alkalines do in the cold. Will find out this fall.

TDI SL draws about 500ma, so about 3 hours of use.

      Can anyone shed some light on the batteries that minelab detectors use?
       
      1. Longevity
      2. Cost to replace
      3. Estimate if those particular batteries may go obsolete (as opposed to AA batteries)

      I am attempting to purchase a White's battery holder, P/N 802-7150. Canadian Treasure Seekers has one in stock, but due to supplier contracts can not ship to US.
      I hope to find a fellow hunter from Canada that is willing to purchase and send this battery tray to me. I will, of course, reimburse any cost for item and associated shipping costs.

      I opened up my TDIBH the other day for some fiddling around and checking out a few things. I powered up the detector with all of the guts and board opened up and had it hooked up to the 14.8v (4 x 18650 cells) battery pack. I had it going for just a few minutes when I gripped the circuit board as part of my “fiddling” around......well I dropped the board and swore a bit in response the burn I was expecting on my fingers. Well it turns out that on the opposite side of the board behind where the big capacitors sit is some sort of heat sink and I can tell you the heat from this spot was something else. The detector has and runs just perfect but the hotspot really surprised me. 
      I decided to hook up the 12v battery pack and let it run for a decent amount of time and it never got past a mild warm on the back of the board. That extra couple of volts is generating some serious extra heat.....bit like on the heat sink area of the CPU chip in your computer.
      I honestly don’t know if the detector can handle this extra heat long term but I’m not taking any chances. I’ve moved back to the 3 x 18650 battery pack which I knocked up when I first got the detector. There is a slight loss in depth but surprisingly not too much. I feel the performance of the 11.1v Lithium setup is maybe 1 to 2 inches behind the 14.8v “hot pack”.
      You can see in the photos the big caps on the detector and where the heat comes from. The other photo is my 11.1v pack which packs some punch and lasts much longer then the stock NiMH pack.

      I seem to have lost my charging cable for my ML 80 Headphones for my Equinox 800. Do I just need a type C cable for that? I have searched high and low for the minelab cable OEM but impossible to find. Any after market ideas? Thanks so much!

      I've ordered the solar charging kit in the picture below.. I bought it because it claims to be able to charge lithium batteries, all the others I looked at said 'only for lead batteries'.. I'm no great expert on these things (you could say absolutely clueless) but I'm thinking about cutting the cord on the car charger and plugging it into the control box.. I've got another 25W panel without a control box but I'm a bit worried what might happen if I hook this straight onto the GPX battery.. I don't want to kill the bloody thing..
      My question is will a 20W panel hooked onto a control box charge my GPX 5000 battery without blowing it up? 
      Thank you very much for any advice on this one.. I plan to prospect areas well away from the power grid and the 12V charging plug in my old 4WD has stopped working since the car got flooded during a river crossing.. If this solar charger does work it'll be a huge bonus for people prospecting in areas far away from civilisation.. Maybe it'll be the game-changer we've all been waiting for 😁..
      I do realise this idea has probably been thought of a million times already, it's just that i can't find any related info on the net..

      I have been married two times and it’s been a long time.haha
      To win this inverter tell me the total number of years to both wives.
      Please only one guess for each person. I’ll stop the contest on 3/17/18 6PM CST and the nearest guess without going over is the winner. If someone gets it correct sooner I’ll stop it then.
