Anyone used li-ion rechargeable batteries?

Post by Hoddie » Fri Dec 30, 2016 6:12 pm

Hi everyone, has anyone ever used li - ion rechargeable batteries in thier minelab sovereign elite?
I have one of these machines but can't find the battery pack.......I do however have the battery pack that you can use normal batteries in! Trouble is they don't seem to last that long.
I'd appreciate any advice, TIA ::g

Give people chance Hoddie, i moved it to the minelab forum so you get answers from people in the know.
I think others have done it if you do a search on the forums here

Cheers mate, I had a good search, I see people have used li-po battery packs and I was going to go down the normal rechargeable route but those batteries are 1.2v (I think) whilst li-ion aa batteries would be 1.5v.
I'm merely trying to get the best performance and time from what I have........
Didn't mean to sound impatient but......well.......I am! Lol x; =))

You could get a set of rechargeable batteries in your battery pack the higher the mAh rating the longer they will last.

I know they are only 1.2v but that is all that is in the original rechargeable pack.

Thanks for the reply, I may just go for that option as there are some good deals on batteries on Amazon atm. Any recommendations? Seen some good Duracell......

I'd take care to test the voltage of the Li-ion group of batteries before you try them. In the same way that single NiMH cells are 1.2V, rechargeable Li-ion cells are usually 3.3 to 3.7V. So if you *can* fit those into the battery pack you will be serving up twice the voltage that the Sovereign expects. :-O. However IIRC most (if not all) are of a size so that they cannot easily fit where alkaline AA batteries fit.
Also IIRC even the single cell non-rechargeable Li batteries are about 1.65V each or 0.15V/10% higher than an alkaline cell, and so eight Li cells are 1.2V higher in voltage than 8 alkaline cells (13.3V vs 12V). This may or may not be a problem for your Sovereign.

Hmmm, I'll stick to standard rechargeable batts then, thanks everyone! :ml

Are you talking about those 'Kentli' Li rechargeables, that have a 1.5V regulator inside them, but charge up (in a dedicated charger) as a regular Li cell? There's a thread on here where they are mentioned, there may be some useful info there:

Thanks for that Fusion, yes that's what I was looking at getting (or something similar) I didn't bother in the end. I simply bought 2800mah NI-MH rechargeables which seem to be fine! They weren't enloops, but I think you need to be a bit daft to buy those as they're not value for money.....but each to thier own!

I have to disagree about the Eneloops. I have some that are over 4 years old and still work the same they did the first day i bought them.

I agree, Eneloops for me all the time. Best by a long way.

I agree, very good batteries......just not the best value for money but as I said, each to their own.

Perhaps you (Hoddie) could tell us what batteries you actually purchased, the discussion might benefit us all. Sanyo-Panasonic are one of the biggest names in rechargeable batteries, and I suppose you are paying a premium price partly due to the Brand. But in various on-line comparison tests, the Eneloop range seem to score near the top, so if you've found some that are good or better, but at a lower price, we'd like to know. The 2800 mAh capacity is impressive, it makes me wonder if they're EBL brand. EBL certainly seem to have competitive pricing.

I think many customers aren't quite so concerned about price, as they think of the long-term cost, and all rechargeables are excellent value compared to non-rechargeables, for most medium to high drain applications.

You hit the nail on the head fusion, they were indeed EBL batts I bought. I'm not saying these batteries are better than the enleloops because they are not.
After carefully researching what batteries to buy these batteries got the go - ahead simply for the value of them.
I took a chance but I believe it has paid off because these batteries are actually very good! They beat normal batts hands down. I'm interested to see how long they hold their charge.....although a mate informed me he has two sets and they still hold a good charge three years down the line, I'm not sure but so far,so good!
If this is the case I'd have to say that's excellent value for money in my opinion and Since I can buy sixteen of these for the price of 8 eneloops then I'm sure you can see where my logic is?
Kind Regards, Hoddie

P.S. - with regards to lithium ion batts they could be used but I have noticed (with a separate device I'm using) the second they get cold the power just seems to disappear!
I left the device in the car when I went to work (with 3/4 battery power) when I came back for a quick break the battery was dead......nothing!

Hope this post has helped.....

Thanks for the reply. EBL definitely seem to be making a name for themselves. They are also being innovative, the Lithium rechargeable PP3 9 Volt battery is an interesting product. I'm surprised no-one else has made them before, essentially they are just two Li cells in series, so 2 x 4.2 Volt fully charged. Many detectors use PP3's, as do most pinpointers, and I've seen the EBL ones mentioned on several detecting forums, over the past year or two.

Interestingly, after charging the EBL batts and getting my multimeter on them they hold nearly 1.3v yet some Duracell batts I had out of a new packet only showed as having just shy of 1.4v? Strange, I'm sure you'd agree.....
As for the pp3 9vbatts I spotted them too, I think they have a charger that does 8 at a time!

I've not seen a 'teardown' of the PP3 Lithiums, but I'm assuming there's an electronics board inside, just like laptop batteries etc. Partly for protection, pretty vital for PP3's as they can be shorted out so easily, and partly to do charge-balancing. This stops one of the cells taking all the juice and frying, while the other gets nothing. They should also be more reliable than NiMH's, which suffer from having 7 cells inside them, if one dies, the whole battery effectively dies.

It's a very broad subject isn't it? Everything from build quality to external stresses such as the weather (hot/cold), charging times....lifecycle, the list goes on!
I hope I didn't upset any of you as looking back I perhaps shouldn't have used the word daft! I merely thought.....who doesn't like value for money, that's silly!
Anyway apologies, time will tell if I'm the daftie.....lol x;
