Not sure on the price but i have just purchased 16 sanyo eneloops for £25 from 7day shop...
My first set lasted 4 sessions of detecting before getting to 1 bar....
Not sure on the price of a rechargeable pod but this way may be cheaper..
And they come ready charged......
1.2v each so exactly right for the etrac and 2000Mah, which makes them last well....
Link is here, they are normaly much more expensive thaan this offer

Yea i decided to go with 7dayshop because i also bought an 8 battery superfast charger +16 sanyo eneloops in plastic cases (well handy) all for £36 delivered....
The charger does 8 batterys in 3 hours from zero to full and can also discharge your batterys should you wish....

Received the charger and 8 batteries today :)
Unfortunately when I found the spare empty charger pack, I noticed on it, "Only use 1.5v" and the Sanyo eneloop I purchased state they are 1.2v :-O :(
To be totally honest I thought all AA`s were the same voltage :-/
Anyway do I need to try and get hold of some 1.5 rechargeable batteries or is it a case where rechargeable batteries somehow use slightly different voltages :-/
Cheers all

Rechargeable batteries are always less than 1.5v, usually 1.2 or 1.3v.

Just try them, they won't cause any damage, they don't have enough current in terms of ampage in them.

Just a little more info back from Techs at Minelab...
Despite the recommendation on the alkaline pod to use 1.5V batteries the unit will function with the 1.2V rechargeable cells. The unit will automatically shut down when the voltage level falls below a certain voltage (this is typically 8.4V). Your batteries have a combined voltage of 9.6V which is sufficient to run the machine. Further to this as you are using high capacity cells (2000mAh) these will last longer than most alkaline 1.5V cells.

The reason it is recommended to use 1.5V cells is due to the battery indicator assuming a 12V input. What you may find is the accuracy of the battery indicator is reduced, it will indicate there is less battery life present than there actually is. From an operational and functional point of view this will have no impact on performance. When the voltage falls below a point which results in performance deteriorating the unit will automatically shut down. So it is quite safe to use your Sanyo batteries with the unit.

its quite hard to find rechargeable batts in 1.5v
Quite hard? seemed impossible to me :)

If anyone actually finds any 1.5v rechargeable please let me know :) B-)

The supplied Minelab SlimPack is a NiMH rechargeable unit and is 9.6 volt / 1600 or 1800 mAh, this is the one that is the self-contained unit.
The battery pod which takes the AA cells, can use either 8 x 1.5AA Alkaline =12v, or 8 x 1.2v NiMH rechargeable AA cells = 9.6volt.
In my E-Trac, I use the battery pod with 8 x 2700 NiMH cells which have the same voltage as the ML Slimpack but they last far longer than the SlimPack - and as they are NiMH cells they can be recharged frequently with no memory effect.

Good point, the supplied Minelab rechargeable battery pack IS 9.6V, so i don't think you need 1.5V batteries, the video might be a bit misleading, is it actually a Minelab video?

The video is a Minelab video :)
As for the batteries you do not need the 1.5 volts but as the video explains, with fully charged batteries you will only get 3 bars display on the battery meter and not the 4 you would with the battery pack.

But that doesn't make sense, as a Minelab rechargeable battery supplied with the Etrac is 9.6V & that registers a full charge

I agree It does not appear to make sense, I can only fathom that the actual batteries in the battery pack are indeed 1.5V making 12V and not 1.2V making 9.6V which is actually printed on the Pack ?

If I use the pack I get all 4 bars but only 3 with the 1.2V rechargeable`s.

I use high amperage rechargeable’s now that are 1.2v in the dry cell adaptor, and they well out perform the supplied sealed battery in my Explorer which is the same as the etrac. I use a fast charger that take 2 hours for 4x Batteries

I have 4 x 2100mAh and 4 x 2450mAh ones, easy does a day session

Got the charger here, as I had some argos vouchers

The other cells are these

Shop arroud though as you can get them cheaper, I was given the Energizers so can't complain

Iv'e been using this set up for about six months, don't know how some of the cheaper battery's will stand up to time ?

Going off on a slight tangent if anyone has a rechargable battery for a Exp/Etrac which is no longer holding it's charge don't throw it away.
All you do is remove the back panel and then split it into two. Take the batteries out this needs a bit of hands on as they are connected with a metal strip to the pod. When you have got them out take an old remote control and take the bit out of it which the batteries sit on (the pos and neg thingy with the spring on.
A little bit of packing and fiddling about and you can put a set of 2700 NiMh's in there A lot better than the 1800 Minelab pod and a lot cheaper as well............

Even better now we have the new RNB Lithium -Ion long life rechargeable the perfect replacement battery for all Minelab FBS machines. See my daughters webshop on this forum for more details. MRix is doing a video revue on it over the next few days and will be putting it on his MDF you tube channel.
