My 901's battery seems tb on the way out. It's down to about an
hour's use per full charge.

Can the existing battery pack be rebuilt using generic cells?

Or should I just order a new one?

I've seen advertisements for on-line companies that install new (I
suppose generic) cells in your battery housing, but I haven't tried
them. The obvious downside is that you must do without your battery
for the time it takes to ship, remanufacture, and ship back. They do
offer to sell you one of their housings with new cells, but the prices
seem about the same as ordering a new (generic) battery from one of
the many companies that sell on eBay. I went that way for a spare for
my old Thinkad T42, and even went with a longer capacity battery, and
it works great.

Anybody tried the 7200mAh from Battery1inc?

viz: http://tinyurl.com/ylnhgac

The price is certainly right...

Rebuilding Lithium Ion batteries is dangerous and probably best not done
although I would not say that it's impossible (if you elect to go that
route, do not do it yourself, have a firm that does this professionally
do it). If it's NiMH or NiCad, then it's straightforward.

Now that I've Googled a little and seen some of the prices for
new replacement batteries, it seems silly to even think about
rebuilding.

I had no clue about the danger issue.

Even though I now realize that buying a new replacement battery
is the way to go, that's still valuable information for later
situations.

What's the danger? Heat from soldering cells? Something about
lithium? All of the above? Something else?

All the above, Pete. They are prone to thermal runaway which
could be triggered by soldering, accidental short-circuit or over-
charging and the last thing you want is molten Lithium exploding
all over the place. A quick google for "lithium battery dangers"
should give you an idea. There's even some actual explosion videos
on youtube..
Best,
