APC provides a power cable that allows you to connect both your notebook power supply and the notebook to a proprietary power port on the Universal Notebook Battery. Make sure that you select the correct voltage for your notebook: there is a small switch on the right side of the device to select 15, 16, 19, or 20 V supply voltage for your machine. Look on the bottom of your notebook or on the notebook’s power supply to check the voltage (half a volt’s difference is usually fine). The switch also allows lets you turn off the APC battery.
Watch Your Power Options!
The concept behind the Universal Notebook Battery has one disadvantage: since it is connected as if it were a power supply, there is no way for your notebook (or for Windows) to know that it is actually running on a battery. As long as your system uses one of the default power modes, such as “Balanced” in Windows Vista, it will switch the system into high performance mode—which really cuts into the potential battery run time increase that the product provides! If you want to use this product the right way, you should create a new power profile that you can use when you travel with the APC battery, or switch to the power saving mode if you can live with a quick and dirty solution.
Manual Battery Run Time Testing
Due to the situation just described, it’s not possible to use any of the conventional battery run time tests such as BatteryMark or MobileMark, which start their workloads after removing the power supply. The benchmarks are smart enough to cancel the run if you plug the APC battery back in, so we had to create a simple benchmark and track the time manually. We installed BatteryMon and looped a DVD vob file using the VLC player off the notebook’s hard drive until the battery (or batteries) were empty.

You would gain about 2-3 hours more using 6-cell MediaBay battery instead of DVDRW drive.
I personally own almost identical notebook (with T7300 CPU) packed up with 9-cell (85Wh) and 6-cell (48Wh) and I got little more then 8 hours at idle.
great stuff! This actually looks like a product you might want to buy.. I only ask myself how good these batteries are on the long run.. how many times you can charge/discharge it and if that's comparable to a standard battery.
Good review!
I went to APC's site and it seems like this product is discontinued.

Yeah, this "review" is kind of strange. The product manuals, if you click on the compatibility guides, are copyrighted in 2004-2005. Little late in getting the reviews in, ehh?
Sooo... is Tom's writing reviews on dead products now?
APC Universal Notebook Battery: 3h 38min

Wow, where did you learn math?
Personally, I like my Tekkeon MP3450. It is truly universal in that it has low amp options for powering my EEE PC - in other words it is universal for notebooks and netbooks. It also has a usb slot for powering devices that way. Sure, its only has 50 watt hours, but you can buy a secondary 50W battery and bridge them for 100 watt hours total. Add on the adapter I can buy to plug it directly into the DC output for a roll-up solar panel, and I am literally a happy camper!
Why don't you guys at Tom's aquire one of these Tekkeon batteries and give us a review?
review should be done 4 years ago.
Maybe they're just getting their 2005 mail delivered over in Germany. :-)
I was going to comment on the math used in the Battery Run Time Results table, but GWolfman beat me to it. They got the total time right in the article, though. 8 hours, 13 minutes.
Just a thought... maybe someone got burned on the legs by setting the battery on their lap while it was charging. APC would cancel it in the States due to lawsuit issues, but might still sell it in Europe where they aren't as litigous.
I like it...for some reason my silly laptop only has a 4-cell battery, non upgradable to larger capacity. Heck, its 14.1" and netbooks have 6-cell batteries.
This one has been out for a while. I got one for my Toshiba M4.. but due to unknow reason, their plug for Toshiba did not work on my laptop. I had to return it... too bad... I never have the chance to know how good it is... >_
Notebooks with the crappiest batteries are the big 17 inch models with discreet graphics - these are the ones that would benefit most from an external battery. Unfortunately the APC unit, as well as others like elektrovaya, offers lousy amp-hour performance for a 17 inch notebook.
But I did find it funny how Tom's chose to go with a small 14 inch notebook for this test with integrated graphics - not exactly a power hog to start with...
Design an 8-hour battery for something like the Toshiba X305-Q708, that will get my attention.
Agreed also, this product is terribly old. Slow news day at Tom's or lack of writing talent for new articles???
THG = fail
Product might be good if it worked. However, with the HP/Compaq MC6400 the APC doesn't work and APC doesnt' care and had nothing to say when we called them concerning the issue of their tip not working with their unit.

Are you saying a European would not sue APC if the battery burned the user?
I have been using a 160 watt Electrofeul from http://www.electrovaya.com/ for 5 years now and it gives me 10-14 hours of extra life.

Uhmmm sounds more useful than an APC battery that is no longer produced...
