rechargeable 9v battery

[MatthewS]

Well I have to ask since you make a good point about the volitale nature of lithium polymer bats. Is the lithium ion a better choice or is it the same. Thanks for all the info. Sqwaby

They are equally volatile chemistrys. That said the LiOn cells are constructed more durably and thus less prone to penetration by water of foreign objects. The cell construction also makes them less prone to internal shorts. It's not that I wouldn't use either, it just that I wouldn't take the chance if it didn't yield some massive benift. At this point we can save massive bucks and have some peace of mind with the NiMh variety. So I'm sticking with those. I mean why take the risk for the added capacity? Who in the hell metal detects for 40 hours straight?

Thanks MATT,and if detector manufactures would take a break on the I D SCREEN, and instead use that large screen area available,could embed small solar panel in that area,for hunters walking and hiking,such as a gold hunter,hiking to distant hunt sites,detector would have a chance to recover charge while hunting!,think of the possibilities!,some hunters have to hike distance,and not having to carry all those battery's would be great!.And the small solar panel would not be to big or heavy,something like calculator panel x 3 or 4.Chuck.

Impractical... Nobody manufactures a product and gives up a feature for something you can have second hand - Portable solar battery chargers.

If your that concerned about green energy, buy a solar battery charger and set it up at home.

I think you have given me right way to solve energy issue..Using solar power will provide me continuous power..

Steve,

There is nothing wrong with that position. But allow me to attempt to appeal to your inner sense of reason and logic, with math and money.. I am using the PowerEx just as an example.

- Duracell alkaline 9v battery - $2.99
- lasts 20-30 hours in your detector, then you toss it.

- PowerEx 9.6v rechargable - $13.99 shipped to your door
- Lasts 22-32 hours in your detector, then you recharge it.

Now assume the initial investment of 32.99 to have a 4 port PowerEx charger shipped to your door as well, thats a total initial investment of $46.98. The absolute WORST your going to do with that battery is 500 charges. The actual lifecycle is on average about 1000 charges. So now we have;

- Powerex package - $46.98
- Reuse the battery 500 times
- Replaces 500 Duracells

- Cost of 500 Duracells - $1495.00

- 500 hunts @ 20 hours, worst case = 10,000 hunts.
- 10,000 hunts @ 20 hours, worst case = 200,000 hours of detecting.

So basically, you pay $46.98 and you never buy another 9 volts for that detector for THE REST OF YOUR LIFE...

$46.98 will get you about 16 hunts buying Duracells. Thats 320 hours of hunting, worst case. If you think your going to live to see more than 320 hours more hunting, it's cheaper to buy the PowerEx package now and get it over with.

Because of this simple math, I no longer buy Alkalines for anything other than emergencies. I keep a stock of C and D batteries just in case the SHTF one day and the power outages are greater that the expected life of the rechargable. Rechargables lose their appeal when you no longer have power to recharge them with

Think it over..

My charger operates with a 12volt supply, it also comes with a car adapter. Another way to do this (without electricity) is to buy a small 12volt inverter to hook up or wire up to your car, this way you can also power small AC devices in the field.
