FAQ

Does anybody know if you can hook a battery pack (jumperleads) up to a normal strand of fencing wire?

No you can't, your battery will short out.

One of the battery pack to die, and a piece of it?

In a piece of battery in parallel with a battery useless.

And for how long? The continuous power consumption is 12v at 2 amps.

Your batteries will have to be in SERIES to get the 12 volts. 1.2 volts each X 10 12 volts @ 2 Ahr or 2000 milliamp hours (mah). So in theory, one hour. Reality is that the cells will not actually produce 2 amps for 1 hour without the voltage dropping off. So a rating of about 10% of the capacity is recommended. Your battery pack would work for 5 to 10 minutes before draining them down at 2 amps and would get very hot in the process! Switching to a 12V gel cell or 10 D batteries would be better.

If i made a battery pack of 13 batteries, each 3.7V 4000mAh in series, then i would get a battery pack output of 48.1V 4000mAh (assuming thats correct).my question is, how would i go about charging the pack? or bertter put, what kind of charger should i be looking for to safley charge the pack?im clueless on how to go about charging it, any advice would help, thanks.

Charging specifics depend on the chemistry of the battery. There are different approaches for lead-acid, NiCd, NiMH, LI-Ion

how do you remove the batteries from the rechargeable battery pack?

I'm okorder

I need a good battery grip for my nikon D90. I've heard the Zeikos is good, but the Nikon grip is pointless for the price because it does nothing for the camera other than extend battery life. Yes you get the reliability of the the brand name, but I don't wanna spend that much. Thanks for the advice prior to your answer.

You can search it online,now I want to reconment a battery shop.

For a polaroid impulse

The batteries are built into the film. If the film is old the batteries are frequently dead, rendering the film useless.

I was looking to getting a Nikon, but it says that the Nikon D3100 and D5000 both use battery packs, are they really worth the trouble? Will I not be able to use my own batteries if the pack happens to go dead?

Those are Li-ion batteries which is the cream of the crop these days. They last the longest. You could buy an extra set of batteries if you are a heavy user. I've even seen a battery pack adapter that uses AA batteries but I'm not sure about it's efficiency.
