Is this feasible?

6V / 10Ah Sealed Lead Acid Battery

http://amos.shop.com/cc.amos?main=catal ... ccn_test=1

It's probably another case of impossibility, but can i use this?
I'm buying two, so it would be 12V total. Can i still use the regulator in the book? Will there be any airline issues? I'm going to scottland, and need a battery that lasts 10-some hours
but doesnt get confiscated while at the airport.

What are the pros/cons to this type of battery, other than it's weight?

Yes, it's a bad idea. (besides the weight.)

-Lead-acid batteries do get confiscated (at least at Logan intl. Airport, not sure elsewhere, I'd imagine so.)

-They take up quite a bit of space

-If you let their charges drop below 1 volt, they will never hold a charge again.

But on the other hand..
10 amps per hour would last for a LONG time!

Battery life shouldn't be a problem, most airliners have outlets and/or car outlets at the seats. Just get/make the proper plug.

10Ah is only the same as about 4 or 5 rechargeable AAs... what'd be cool is to have a portable with two power sources that could be switched so that gaming couldn't be interrupted. Then you could just have a set of batteries on hand and swap them out as battery power gets low. I really want to try using 2 AAs to power a system and a screen using pull-up stuff. With those you are guaranteed only the voltages you want and less wasted power from pulling down. Of course, you're kinda stuck with very little power at those voltages, which makes power conservation and low-power parts all the more important.
Also, my flights have never had power plugs (that I've noticed...)

Some of mine have, but if you are flying North America to Europe, make sure you know if the outlet is PAL or NTSC power.

Actually PAL and NTSC refer to television scanrates; These frequency standards are not used when referring to wall outlets. We are about the only nation in the world that uses 60 Hertz AC power; the rest of the world uses 50 Hertz. European voltages are 220 instead of 120.

Just use a PSOne screen power plug, because it's a switching power supply, which can accept frequencies from 45-60 Hertz and 100-220 volts. Be sure to check, though, because I am basing this from memory.

I know, but some people here only understand that there is a difference if you refer to it that way. I guess I should have typed it properly, but I was lazy. And you aren't the only "nation", we are the only continent.

Well, There's Another Idea Shot Down...

Tune in next time, when Sweebez experiments with a cold fusion SNES.

Oops, yeah you're right. Canada, Us, and Mexico all use 60 hz. Sorry.
I was confused because Canada and Mexico use the metric system.

LOL. Does anybody know of any other country that uses Imperial Standard measurements, other than America?

Some Carribean countries use it, but more or less everyone else has had the common sense to change to metric

Catch up guys!

10Ah is only the same as about 4 or 5 rechargeable AAs...

At 1.5Volts, yes. If wired in parrallel, the Amperage and available mAh is added together. However, in series, the the Amp/mAh stays the same as one battery.

The main trouble with lead-acid batteries (except the whole no air line travel thing) is they're fairly heavy, due to being made mostly of the dense element lead.

What are you talking about?
He's talking about a 4 or 5 cell parallel 1.2V battery pack.

Yes. Rechargeable AAs are NOT 1.5V either, last I looked

I wasn't actually thinking of hooking up cells in parallel, more "let's just carry extras as needed." I mean, depending on one's usage, 10Ah may just be overkill. Hooking up cells in parallel is dangerous, since they can charge (and explode!) the sister cells due to an imbalance of discharging. Even hooking them up using different amounts of solder on the connector could cause this to some extent over some time, and it'll just screw up the batteries faster. Not a good plan.
You're both right though. Parallel would give more Ah, serial gives more voltage. So that'd make it a huge fiasco, with 25 batteries to get 6V 11Ah. Doesn't sound ideal for a portable system.
Should I get around to building a portable, I'm planning to tinker with voltage pull-up to get the most out of the few batteries I'll probably use. I'm not sure it's feasible but I like the idea that power won't be wasted in any part of the system.

You live near Logan? Me too. What state do You live in?

I think tom61 meant 4 regular or 5 rechargables. That makes most sense, because 4*1.5V=6V and 5*1.2V=6V. Anybody else see how he could have perceived this to be the meaning?

LOL. Is perceived even a word?
