I see RNB based in USA sell these battery packs specifically for the AT series, they are lithium,hold charge for much longer than standard and rechargeables, also lightweight (y), would like to know if anyones using these? I see they have a higher voltage than the standard batteries?
Technical Information:

What is the nominal voltage of the pack? 6.2 V
What is the fully charged voltage? 13.8 V
What is the mAh capacity of the pack? 2200mAh

I use the standard AA batteries in my AT PRO and get good life out of them. Was thinking of maybe getting rechargeables this year but haven't decided yet.

I think i get good life out of my AA rechargeables too, cant always believe the sales hipe , but i like these as there's no messing around swapping batteries and the lithium really do last a long time without charging , i have one in my motorbike and it always cranks over even after not riding for awhile, so far had it for 4 years and its been great!

We changed to Nickel metal hydride batteries 5-6 years ago and the make is Vapex.
It looks like Amazon finally stock them, they come in packs of 4 in a protective case and work at 2900 mAh.
We've never needed to change them ever when out on an extended hunt working an 8-10 hour hunt.
We always took spare batteries but in 5-6 years never needed them.
They're bright orange in colour, easily recognisable.
They have to be the best available world wide.
We have never had batteries that could even come close to them.

I believe they do a fast charger for them too, but we just used our normal charger.

Thanks Ian for the tried and true testimonial. It is always good to hear it from someone you trust.

If I remember correctly, I couldn't use lithium batteries in my minelab, too strong, I looked in the AT Pro manual, and couldn't see where they said, one way or the other. I didn't know you could get lithium rechargeables, but sure will look into it. If anybody has any more info about using them, please let us know.

Found more info, NiMH rechargeable batteries may be used. Lithium doesn't make rechargeable ones.

I am absolutely WRONG. Saw a detecting you tube vid on the RNB Power Plus Battery Pack, and looked them up for sale, and they are Lithium Battery. Many good replies on them, and a few poor remarks. The cheapest I saw them for sale was $75.98, and probably shipping on that yet, so not cheap. Some are getting great hours out of them, and it seems that the people using them in the AT Max, pretty normal 8-10 hours, but the Max has stuff in it that uses more power. Going to look up the mAH rechargeable ones and see what they might have.

I just bought these 12 rechargeable AA batteries and charger from Amazon and together they set me back $62 shipped.
My AT MAX gets between 7-8 hours per charge so using regular batteries would cost me a fortune. Four of the batteries will go in my Max or Pro and two will go into Sue's TreasureMaster. The other six will be backups in case we need to replace a set in the field.

I read about some Eneloop batteries, and they sounded good, I didn't need a charger since I already had a couple. I made a mistake on buying a Duracell charger that came with 4 batteries. Got home and found out they were only 1300 mAh. The ones I have coming are 2800 mAh, so should handle much more power drainage. I used alot of of different types with my last detector, and think ( for now ) will stick with the AA rechargeable batteries

Just FYI, I have the RnB Battery Pack for my At Pro, and it is sweet, great quality charging system, it took mine around 45 minutes to get a full charge, and it fit great in the detector. Hopefully it will live up to the 40+ hours running time they claim.

I'm pretty sure the 40+ hours are on using headphones all the time detecting, that is an energy saver for sure. Time will tell.

So far the RnB Battery pack seems fine, my detector hasn't caught on fire yet. I have turned on the Pro every day, and the battery charge indicator shows full charge after about 2 weeks. I also bought some silicone grease and lubed up the battery cap cover on machine, losing snow quickly lately, so hope to get out soon for a better test. Hope this darn virus doesn't mess things up !!! :(:mad::rolleyes:
