Erikk the battery holder only takes 8 batteries.
8 rechargeable DD batteries @ 1.2 volts = 9.6 volts
8 alkaline DD batteries @ 1.5 volts = 12 volts
The Explorer runs on 12 volts,
the detector would probably operate on 9.6 volts,
but I guess not at its full potential.
I had a Garrett GTI2500 that could operate from either 8 NICADS or 8 alkalines,you could set the detector to accept either,
but for some reason our Explorers don't have the same ability.

Hi erikk,
You can run any of the Explorer on 9.6 Volts or 12 Volts, as the control panel has it's own built in voltage regulator it will work at maximum performance regardless of the battery pack, You will notice that the sealed battery supplied with the explorer is only 9.6 volts. I purchased a couple of empty battery holders from Minelab and have been using 2300 mah 1.2 volt rechargeable batteries for 18 months with no adverse effects.
Regards Boony

Snowy, Do you mean AA cells instead of DD? In the states its AA. Anyway I see they now have 2500 Mah AA rechargeables on the shelf.
I have not purchased a full set of those yet to see how well they work. The next rechargeable cells that I get will have to be 3000 mah. They have them in C cells, has any body seen the in AA's.
Thanks

The 8 alkaline at 12 volts will work too as the Explorer has a voltage limiter so less than 9.6 is being uses.As you notice the factory pack made for the Explorer has 8 of the rechargeable cells which puts out 9.6 volts.
On your Garrett it could be set for the alkaline or rechargeable, but that was so the battery gauge would work correctly and never affected the way the detector worked as the detector took less then the 12 volts to work with a voltage limiter built in too.

At the risk of sounding stupid here...let me throw this out...First off I'm gonna admit that I don't know...If I had the schematics I might be able to say for sure...But I believe that Most detectors have voltage limiters in them & I also think most are designed to run on far less than 9.6 volts otherwise they would not be able to operate at optimum levels for any length of time...ESPECIALLY with the rechargables....Just my personal speculation

Boony,
Your right about it saying 9.6 volts on the sealed battery pack BUT the actual end charged voltage of this pack can be up to 11.4 volts(measured with a volt meter).
For the charging input voltage of 15 volts that comes from the Explorer wall charger, that goes into these sealed battery packs, there is a small circuit that, I believe, might ne an intelligent inverter/regulator pulse circuit, built into the sealed battery pack of all the Explorer generation nimh packs. The input of power be it through the wall charger or the CAR charegr through this circuit inside the 8 x AA 1.2 batteries are being charging up to 11.4 volts.
Basically you could say that there is "blood being got from a stone here." Somehow , 8 x 1.2 that should equal 9.6 volts is being made to charge up to 11.4 plus volts.
Recently in my quest to obtain a similar power output from 8 x 1.2 nimh on my chest mounted underwater explorer, I obtained an intelligent after market charger that allows the 8 x 1.2 nimh to be charged as a bank of 8 batteries, NOT INDIVIDUAL, to 11.4 - 12 volts volts. This allows these 8 x AA to last with a charged usable voltage longer.
The charged up 8 a AA nimh last as long as, if not longer(depending on the mAh rating) as the Minelab sealed packs 1600 mAh packs.
The batteries I use, ALL carry a variable charged voltage for each battery but none are charged less than or equal 1.2 v. The batteries are always equivalent in charged voltage to eahc other and will go up to 1.5 v and but never less than 1.43v. Not sure how this is
.
I like to add that I had been encountering all sorts of problems with using even 8 of the best quality AA nimh in the packs supplied that were meant for and designed mainly to be used with the Alkaline 1.5 volts. That would make this pack equivalent 12 volts. If find them , then are some AA nimh batteries do physically fit.
For me, they seem to be the cause some wierd inexplcable gliches with mt Explorer xs and Exp 2. I have not tried them in my Expl SE..............yet
All I know is that after I encountered the problems I did( using 12 volt gel cells and other types of battery supplies, I went back to either 8 x AA 1.5 Alks(they're cheap enough Bunnings 20 for Au $9) or after market AA nimh that are charged up in the way I eventually did or the Minleab supplied battery packs.
