I have a HP Pavillion 2.4Ghz 14in laptop and the battery life has never been
particualarly good. For some reason HP decided that a tiny little 4400mah
battery is plenty big enough, not sure what they were thinking.

Anyway you can get an 8800mah HP replacement pack for reasonable cost if you
shop around.

Any reason not to do this?

Cheers.

Pete

Well Pete... they are usually much larger and thus stick out the back
and/or lifts the bottom of the laptop higher. Plus longer charge times.
Otherwise it is what you should expect it to be.

In this case the original battery is quite small (only 4400Mah) so the bit
that will stick out will not be that big and will probably put the keyboard
in a nicely angled position. I was thinking more about the extra heat from
longer running times but of course it will probably not get as hot as when I
run it on power because then I run it in high performance mode rather than
in preserve battery mode.

Cheers.

4400mah isn't that small.

It's worth noting that when multiple batteries are offered for the same
laptop, the mah is normally almost constant for all of them. For
example, for a number of laptops, Toshiba offers a 4-cell, a 6-cell and
an 8-cell battery. They may have the same mah; it's the voltage that is
different (since the cells are in series). 12 volts at 4400mah is twice
as much power as 6 volts at 4400mah, and will last MORE than twice as
long (mah is calculated by draining the battery over TWENTY HOURS; you
get more total power delivered if you drain it slower; if you cut the
current drain from any given battery in half, it will normally last more
than twice as long).

Not so with these and can't say I would have thought that to be the case.

The physical size of the original 4400Mah 10.8 Volt battery is about the
same volume as my 6600Mah 7.2 Volt battery in my ASUS 1000H, they also weigh
about the same.

My Eee PC 1000HD 7.2V 4400 mAh and 7.2V 6600 mAh batteries are exactly
the same size because they use the exact same case. Inside the case
there are cutouts for 6 cells but the 4400 battery only has cells in 4
of the cutouts whereas the 6600 has cells in all of them.

Pete,

I hate to tell you this, but of your two batteries, 4400mah and 6600mah,
are electrically identical in size; neither is larger than the other:

4400 * 10.8 = 47.52 watt-hours

6600 * 7.2 = 47.52 watt-hours

mah is NOT a measure of capacity, rather it is a measure of one aspect
of capacity.
