THIS IS NOT MY TEST I COPIED THIS FROM HERE http://forum.snipershide.com/sniper...heon-w1000-9-battery-performance-testing.html
Folks,
For those of you that own W1000-9 systems, I've tested the following batteries**:
- Energizer Advanced Lithium 9v batteries (x6) [Done; see below]
- Utilitech 9v Premium Alkaline batteries (x6) [Done; see below]
- Engergizer Alkaline batteries (X6)
- Duracell [Copper Top] Alkaline batteries (X6)[Done; see below]
- Duracell Procell Alkaline batteries (X6) [Done; see below]
- Maha PowerEx MHR9VI IMEDION 9v batteries (x6) [Rechargeable] [Done; Tested 5 recharge cycles.]
- Ansmann Energy 8.4v NiMH 250mAh [Rechargables]* (x6)[Done; Same results are the Maha, ~4 hours]
- iPowerUS Professional 9v 520mAh batteries (9.6v)(x6) [Rechargeable] [Done; see below]
- Maximal Power 9-Volt Li-ion 550mAh Batteries (8.4v) (x6) [Rechargeable] [Done; see below]
The PowerEx is a low discharge 9.6v NiMH rechargeable battery that delivers 230mAh.
The iPowerUS Pro 9v is a 9.6v Li-ion battery that is supposed to deliver 520mAh, and is rechargeable.
The Maximal Power 9v is a 8.4v Li-ion battery that is supposed to deliver 550mAh, and is rechargeable.
Best disposable battery:
The Energizer Advanced Lithium is the best battery set so far.
However, for Energizer disposable lithiums to be cost effective, they need to run for about 15 hours; Energizer lithiums batteries run for about 10.5 hours. At 3 times the cost of most Alkaline batteries, they do not deliver 3 times the performance.
Best rechargable option:
THE BEST RECHARGEABLE BATTERY IS A TIE...
If you like rechargable batteries, both the iPowerUS 9.6v Li-ion 520mAh and Maximal Power 8.4v Li-ion 550mAh units are clear winners; these batteries are superior to Alkaline batteries, and are rate for 1000 charges. They last ~7-7.5 hours, well exceeding any alkaline battery or NiMH battery tested so far.
(As a side line: it's important to note that the voltage is not the important factor in the testing of these batteries. The single most important issue is the ability to MAINTAIN energy drain (aka current) over time. The Li-ion type battery are superior in this. It doesn't appear to matter if they are 9.6v or 8.4v, they still run the sight for at least 7 hours.)
Testing procedure:
The batteries where tested using an iPhone adapter attached to the W1000-9, and it takes a time lapsed picture every 1 minute. When complete, the tester goes to the point there is no picture, divides by 60, and the number of hours the device ran is known.
Note on cost effectiveness:
I spent a fair amount of money testing all of these batteries. It's important to note that, with the exception of General Purpose 9 volt batteries, ALL of the batteries tested were able to run the sight on ONE 9 volt battery.
However, even with the cash I spent on the test batteries, I'm STILL saving money over the cost of purchasing even cheap disposable alkaline batteries!
This is an except from a post below:
"1000 uses of a W1000-9 with Alkaline batteries would be 6000 9 volt batteries(!).
1000 charges of the iPowerUS batteries would use 6 batteries. Assuming that you only get 75% of what the manufacture claims, you STILL only went through 6 batteries. (The manufacture indicates they will last 1000 charges.)
6000 Duracell ProCell batteries times $1.74 each is $10440.00!
Even the worst case senario, where the iPowerUS li-ion recharable batteries only recharge for 750 times, the comprative cost of the Duracell ProCells would STILL be $7830.00!
At those numbers, even the ~4 hours of use you get out of the PowerEx IMEDION True 9.6 NiMH, they become a great deal, since they cost about $90.00 if you shop around and get the 10 battery charger."
The only aspect of rechargeable batteries that is an issue is convience. Even the li-ion batteries take 1 hour to recharge...

* These were sent to me by mistake and I opened them prior to noticing they were not what I ordered in a different packaging. They appear to NOT be low self discharge NiMH.
** Final runtime numbers:
- NiMH low-self discharge -> ~3.8-4 hours
- Alkaline -> ~5 hours
- Rechargeable Li-ion -> ~7-7.5 hours
- Disposable Li-ion -> ~10 hours
