You might think that with only one supported battery for the D1 family of cameras, the Nikon EN-4, things would be simple.
But they're not. Batteries and battery lore generate nearly as much discussion on the D1 lists as image quality. This article will help you know what you need to know about using your batteries correctly and productively.
The Nikon EN-4 rechargeable NiMH battery
The EN-4 battery is the only one that Nikon supports for the D1. Unless you are lucky enough to be able to plug your camera into a power supply it is probably how you will power your camera.
For those of us used to Lithium batteries in our PCs, phones, and digital video camcorders, NiMH is a large and unfortunate step backwards. NiMH has three major disadvantages: First it has a "memory effect" so that it needs fairly frequent deep discharge cycles to function at full capacity. Second, charges deteriorate, so if you leave your batteries alone for a few days they will have lost much of their charge. Third, it is very hard to accurately meter NiMH batteries, which explains why the D1 family meters are a little random in their behavior.
Additionally, the deep discharge requirement means that we need to carry around the bulky and expensive Nikon MH-16 quick charger. The car charger is a convenient alternative but it does not offer the deep discharge feature.
So what does this mean to us?
Discharge early and often!
First, deep cycle (charge and then deep-discharge) your new EN-4 batteries 3-5 times after purchase. If you don't you will only get a fraction of the possible image captures from it. If you didn't do it right away when you got the battery, do it now. It's never too late!
From then on you probably want to deep discharge your en-4 batteries every 10 charges or so, and at least once per month. Personally I have found once per month not to be often enough to maintain peak capacity and am moving to once every three weeks.
Similarly, having too many batteries in your rotation can cause your batteries to sit idle for too long. This tends to cause them to lose some of their charge and then get a "top-off" charge when you're ready to use them. This makes the memory effect a real problem.
But what is Too often?
NiMH batteries are only good for 100-300 charges, and deep discharges definitely wear on the battery. So don't discharge any more often than you think you need to to maintain battery life. Since a full discharge and charge cycle can take 12 hours you probably don't want to be doing it all the time anyway!
Keeping track of your batteries
I do four things to keep track of my nikon en-4 batteries.
I put a file folder label on the flat side of the en-4 battery. So far I've had these labels on batteries for over a year without them falling off. I put a unique number on each label.
I write on each battery each date that I deep cycle the battery. I can then easily keep track of when it needs to be cycled next.
I leave the end "tab" out on dis-charged batteries. At first it made me nervous the tab might get damaged, but after 18 months nothing has happened to harm any of them.
I have my fully charged batteries in one side of my backpack and the dis-charged batteries in the other. This helps make it easy to reach for the right battery when I'm in a hurry.
Other photographers worry about the exact order in which they use batteries. That is probably a great idea, but I'm just not that organized. I just work to make sure that I use each battery before starting to recharge the others--at least when possible.
When do you switch batteries?
With the original D1 Nikon let the battery get quite low before indicating "half full." The camera seemed to get a little flakey after that so the conventional wisdom was to change batteries when they went to half full.
However, in response to plenty of complaints about the D1 surprising people with an empty warning, Nikon has made the battery meter much more sensitive in the D1X and D1H. So you may find that the battery goes to half full very quickly. There is no way around this except to keep shooting. It's a bit of a pain in the neck as the viewfinder display dis-appears if your finger is not on the shutter, but the camera continues to work normally until the battery is nearly empty. At that point it reserves enough power to write all your current images, so it starts getting sporadic in its response to the shutter. That's how you know you really do need to switch batteries!
Carrying your Batteries
This is pretty simple, but there are a couple tips even in this area.
First, if you are placing your batteries somewhere where they will touch metal you'll want to keep the battery cap on them so that they don't short out. Personally I prefer to keep my batteries away from any metal and then don't bother with the caps. They are just too much to worry about when I'm shooting.
Second, as Moose first figured out, the Cellphone pouch from Lowepro makes a great battery holder that can fit on your belt or the strap for your pack.
We hope this helps you get the most out of your nikon en-4 digital camera batteries!

Dell Inspiron e1505 Review (specs)
The Inspiron e1505 is Dells 15.4" widescreen notebook featuring the impressive new Intel Core Duo CPU. A virtually identical Inspiron 6400 is available through their business site. Outside it looks just like the Inspiron 6000 it replaces, but the new hardware inside makes for impressive performance. In traditional Dell style, the E1505 is well rounded, quite customizable and available at a competitive price, but doesn't offer anything radical.
The E1505 reviewed here was configured as follows:
Intel Core Duo Processor T2500 at 2.0 GHz per core.
15.4" Ultrasharp SXGA+ display with TrueLife
512MB DDR2 533MHz RAM in dual channel mode
Integrated Intel Graphics Media Accelerator 950
100GB 5400RPM SATA Hard Drive
8X DVD +/- dual layer recorder
53 watt-hour 6-cell dell inspiron e1505 battery
Dell Inspiron E1505 Laptop Battery:
With the smaller option 6 cell laptop battery and a powerful new processor, I didn't have very high hopes for battery life. However, the Dell lasted longer than expected. At maximum brightness, it played a DVD for 2 hours and 30 minutes. Under normal light tasks, with WiFi on and almost maximum brightness, the battery lasted almost three hours. Dimming the screen all the way and shutting wireless off squeezed almost 4 hours of total battery life. I could burn the battery in about 90 minutes or less if I really tried. Gaming would likely burn it this fast.
The optional 9-cell battery, which is the same physical size as the 6-cell, should give about 50% more run time.
The battery charges fast for the first 80%. At nearly 1% per minute, you could get a significant boost on a one hour layover at the airport.
A bigger laptop battery might be a better choice than two batteries. Lithium-Ion cells wear out even if you don't use them.
