Thanks for the tip so I won't fry my audio board

I bought the non-alkaline AAs because the alkalines are about 4 times the price. Four Panasonic non-alkaline AAs will cost about R$ 2,00. Two alkaline from the major brands (Panasonic, Duracell, etc) AAs will cost about R$ 4,00 or more.

So I guess the non-alkalines are more cost effective here in Brazil.

As for the 9V batteries, non-alkalines will cost about R$ 4,00. Alkalines will cost more than R$ 8,00.

It took me about four and a half days of continuous use to deplete a standard Duracell 9V battery, wich costs about R$ 10, with my zapper/SP assembly. I don't know if their charge is different from the ones in the USA.

A rechargeable 9V of 200 mAh will cost R$ 15,00 to 20,00. A double charger will cost about the same. So going 24h/7d with a SP costs a initial investment of about R$ 80,00, wich is still better than spending R$ 15 to 20,00 every week in 9V batteries (quite a bite in the budget).

So rechargeable 9V are a must here if you plan to run the SP with 9V batteries 24h/7d.

For the sake of comparison the Brazilian minimum wage is about 620,00 R$ per month (hard to live with). 20 kilograms of ortoftalic polyester resin costs about  R$ 230,00 without shipment. Current "Real" to Dollar quotation is of about R$ 1,78 to each 1 Dollar.
  

I use Uniross 9v rechargeables, they cost £6 each (including shipping on Amazon UK) and power my T-Rx zapper for about 3 days non-stop before having to recharge.
I have three of them so after a small initial outlay (including the recharger) my battery buying days are over.

They are 200mAH, 9V, Ni-MH batteries.

9V alkalines have a power rating of 650mAH so they're more than 3 times the life though, continuous, they only last about a week.

That they can be recharged 500-1000 times sure doesn't hurt things but unless you're running the zapper continuously and instead just using it for a couple hours, 9V batteries last a long time.  At say 2 hours/day with 9V alkaline, you'd get almost 3 months usage out of them  (Don's zappers - all I have to use for comparison) - a good month and a half if you wore it for 4 hours per day and probably close to a month if you wore it for 8 hours per day.

If you don't want any down time as you've determined would be an issue, having at least 2 rechargeables is necessary because good 9V rechargeable NiMH batteries take about 16 hours to charge normally where some can be quick charged (if you have the right charger) but this takes about 5 hours.  Because the makeup of a 9V battery is 6 smaller than AAA sized cells inside in series, you can't quick-charge these nearly as fast as single AAA or larger cells (these can sometimes be quick charged in an hour).

Though I can't attest to quality, you can buy NiMH 300mAH 9V rechargeables from vendors in China off ebay for usually less than $3 each including shipping.
  

Hello,

about good 9V battery...I have 4 of them :
http://www.ebay.at/itm/2-9V-6F22-Li...=item4ab4dbddd3
I run continuosly PW and zapper..They last much more than standard rechargeable NiMH batery.
and...I recharge them with a standard NIMH Battery charger, one without any test check or memory check.

These Uniross 9v's take 14-16 hours to recharge fully.

I use my T-Rx zapper 22hrs a day, everyday (by far the best single device I have ever invested in).

In the grand scheme of things I'd rate this zapper as number one, then an SP has to be second (no working SP means no gifting runs, at least in my case) then of course substantial amounts of Orgonite in the home, garden and surrounding area.

I'm wondering if any of Karl Welz's manifestation devices could be used instead of an SP/Powerwand.

Michele,

Those 9V lithium rechargeables cost each about as much as THREE 9V NiMH ones (probably 4 because the eBay vendors who sell these usually don't charge any shipping) and aren't even double the energy content of the NiMH.  You can get 300mAH NiMH cells.  Yours are 450mAH.  There are plenty of better 9V lithium cells out there that are 600mAh which is only 50mAH lower than a 9V alkaline non-rechargable that really don't cost any more than what you spent for yours.

Also, 9V lithiums are usually 8.4V fully charged.  9V NiMH are usually 9V fully charged.  A small difference but a difference.

A 300mAH cell is enough to keep a T-Rx running for about 4 days continuous.  It doesn't take nearly this amount of time to charge a 9V NiMH cell but then you'd have at least 8 of them for the cost of your 2 lithium batteries and with a dual charger (most are) you can keep 2 of them fully charged while using a 3rd so I really don't see the benefit of spending the extra money.

Lithium cells do have one distinct advantage.  Unlike NiMH and the older Nicad ones which have an internal discharge of about 10-20% of charge per month, Lithium cells internal discharge is almost negligible.  A fully charged cell forgotten for a year in a room temp place will be almost still fully charged when you find it again.  A NiMH battery will be quickly heading toward dead.

I use my T-Rx continuous when I'm poisoned or something funky is going on but usually only 2-4 hours per day otherwise.  Seems to work just fine.

I have 2 SP's - one Don so graciously gifted me and a second I built myself with a slightly smaller crystal -both running at the same time.  This way, when I go out gifting I can take one with me and still have one running at home.

One thing I do want to mention about lithium rechargeable batteries as a warning (ALL lithium rechargables are like this including cell phone batteries).  You CAN overcharge them so do use a good charger.  A good charger will not overcharge them.  You also need to let them trickle charge for a couple hours after the charging light goes out so they reach full charge.  Because of lithium chemistry all quick chargers cut the quick charging off before the cell voltage reaches final value and there could still be 10-15% charge they need to get to full power. You can drain them too low where they can't be recharged.  What you need to look for are cells that are claimed to be "protected" or have a protection circuit in them.

Why?  Well, lithium is funny chemistry.  The cell needs to be carefully charged by the manufacturer to about 2.75V before you get it so it can be normally charged.  If you plug a cell thats below this voltage (maybe 2.5V or so) into a rapid charger, not only could you permanently damage it, it could become dangerous and perhaps even rupture.

The protection circuit cuts-out the battery when the voltage gets too low so you don't deplete the cell below the limit.  Though with a good charger its not necessary, it also limits the charge current to something safe AND limits the discharge current to whats considered safe for the battery - the other thing about lithium cells - you should never draw more current from them than is recommended by the manufacturer.  This too can damage the cell and cause issues.  Built in protection circuitry prevents this from happening.

With the protection board inside the cell you can use it like a normal battery.  Without it, you have to watch like a hawk so whatever you buy, make sure its "protected".

I suspect 9V batteries are all protected because of how they're used.  Don't make this assumption for any other cell configuration (AAA, AA, C, D or even some batteries that are a non-standard size to be used in flashlights and the like).  If it doesn't say "protected", it most likely isn't.

NiMH batteries don't have any of these quirks albeit the energy density is about half that of a lithium battery but as I said, the cost differential is huge.
