DURACELL AA BATTERY QUESTION

[daverave]

can anyone tell me the capacity in ah of duracell aa standard alkaline batteries....say at 100ma drawing current.

I can't answer your question. But some time ago, when I was looking for good AA battery for my LED flashlight I found a test of AA batteries available on the market. And I remember that Duracells were not so good compared to cheap AAs from popular markets (i.e. Tesco or ASDA).

Why dont you just look at the spec sheet ?

Yes! My son did the battery comparison for a middle school project and he found that Ray-o-vac batteries, (the cheapest we found were at the dollar store) out lasted even the rechargeable.
A rechargeable battery only costs 1 penny to recharge and delivers up to 2550ma but the voltage is a little less. It is 1.2 volts instead of 1.5vdc for standard batteries.

Well wikipedia says this" Primary (non-rechargeable) zinc–carbon (dry cell) AA batteries have around 400–900 milliamp-hours capacity, with measured capacity highly dependent on test"

But elsewhere I found this quote" These are your standard 1.5V AA alkaline batteries from Duracell. Don't even think about trying to recharge these. Roughly 1500mAh per. "

So I'd guess you could count on around 1000ma from a typical alkaline "AA" cell.. So 10 hours at 100ma draw.

not very good running time from duracell considering the price...i was talking to someone yesterday who sells batteries and he told me duracell are not as good than his cheaper batteries....so i think that i will go for the cheaper batteries and lithium rechargeable battery pack.....1000ma for me is unacceptable considering the cost of duracell.

If you need 12 V just switch from 8 AA to three Li-Ion 18650 rechargeable batteries and you will have 12.6 V power source. (4.2V in full charge for each battery)
1. Rechargeable. You will save a lot $$$$ and save Earth from tons of trash.
2. Powerful. 2200, 2400, 3000, 3800 mA/h. Contains much more energy that AA.
3. Reliable. You will have only six non soldered contacts to fail instead of 16 contacts if you using 8 AA. Bad contact in battery pack is most common failure in metal detector.
4. Light weight. 6 Li-Ion are lighter then 8 AA.
5. Cheap. Check on eBay.

only you forgot to add. li-ions need in special charger and special electronic pcb/circuit that will switch series connection in parallel connection, for the charge. another way you will take out them every time from holder for the charge.

i see on ebay that you can buy li-ions 9000 mah 12v battery pack with charger for less than $30

Lithium polymer are pretty good - giant shark do loads - and a charger for about £6 - I have them in my IDX. Also Li-Fe (Lithium Iron) not lithium ion are good they often look like an oversize AA - I rip them failed laptop batteries - often the pack has 1 dud only. S

Hobbyking has a UK warehouse now. Loads to choose from there.

If you look for indeed good batteries...

Claimed and measured capacity:

This is for 18650 cells you forgot to add.

Yes. Not problem.
Those are suitable for Deus coil. Also having much larger capacity than original Deus accu.
Also those can be connected in series and give 3x3.7=11.1V or 4x3.7=14.8V and than used with majority of detectors.
Considering large capacity i think those are good to think about.

Facts:
18 - The first two digits "18" stand for li-ion battery diameter in millimeters. In this case width of the battery is 18mm (millimeters).
65 - The third, and fourth digit stand for length in millimeters. That would be 65mm.
0 ? - For those who want to know why zero is there, this is how battery manufacturers calculate batt. length: 650 divided by 10 is 65mm. Since we are simple people we will forget about zero for now.
