I have just acquired an HTC Touch Diamond - battery life is bad! With my
prev Pocket PC an HTC TyTN I used to put it on charge when I came home
from work and it was charged up by bed time so I took it off charge. The
battery would last for a few days with bluetooth turned on. With the
Diamond If I charge it when I come home it may or may not be fully
charged by bed time and if I take it off charge then by the following
afternoon the battery is getting low!

If I leave it on charge overnight will this be ok?

Sure. I often leave my device to charge overnight. My pattern is
I let it charge when I get home and within 2-3hrs it is full. If
I get home late though, I am asleep before it is topped off.

The Diamond Touch is a great device, but the battery performance is
poor. Expansys-USA has an extended battery on pre-order -
http://www.expansys-usa.com/p.aspx?i=166204.

If you're in the U.K. or Europe, it's already available for sale on
Expansys U.K. website.

As has been explained in many of my articles, you can safely leave factory
(!!!) batteries on the charger. (Not so with cheap Chinese ones, which, in
many cases, even lack overcharging protection.)

You can't overcharge a lithium ion battery with the factory charger, even if
the device doesn't switch to trickle mode. Nicad batteries can be damaged by
either overcharging or discharging below 1 volt per cell.

Note that I spoke of factory *batteries*, not factory *chargers*. I've seen
several non-factory batteries NOT having overcharge protection circuitry.
Some of them (for example, HardCE's iPAQ 2210 batteries) even died on me
because of this.

Also, you should be careful on these batteries that do not have overchage
circuitry. Lithium Ion is not very forgiving if it is overcharged. Search
the web and you can see lithium ion batteries fail from different companies
with firey results.

Exactly. This is why I'm emphasizing to stay away from cheapo Chinese cr*p
like HardCE's batteries.

The subject of lithium ion batterys is a complex subject. The advice of
sticking with OEM batteries and chargers is the best way to go.

That being said, the charging system on any product that uses a lithium ion
battery is a "three legged stool":

1.Most of the batteries sold have internal voltage limiting. The battery
internal resistance is high, so the charger must deliver a higher voltage
than is normally used for nicad or Nmh batteries. The battery is considered
fully discharged at some point between 2.5v and 3.0v per cell. As the
battery begins to charge the voltage level rises. The battery is considered
charged at 4.3v per cell. The battery uses internal voltage regulation to
prevent the terminal voltage to exceed 4.3v per cell. A voltage higher than
4.3v per cell causes "plating" which permanently damages the battery. A
voltage of less than 2.5 volts per cell may allow corrosion to begin, which
also damages the battery. Most batteries also have internal current limiting
and thermal protection. The ability of the cells to deliver current is
reduced as the ambient temperature is decreased. In normal use the lithium
ion cell may last only two or three years if it is cycled all the way to
being fully discharged. The battery may last for many years with more than
500 recharge cycles if it is kept charged. LI batteries should be stored
fully charged, and will last longer if refrigerated when they are not being
used. Common battery failures are due to plating or internal corrosion. High
temperatures or physical damage can cause failure of the separator between
the cell's anode and cathode. When cells are shorted, the high current will
cause ignition of the lithium. A lithium fire is extremely dangerous.

Sony has the original patent on the LI battery. When incidents of battery
fires first occured, the problem was fully investigated. The details were
not released, but the investigation resulted in a gigantic recall of
batteries that were supplied to many different manufacturers. As a result of
those fires, some companies have warned against leaving LI batteries on
charge when you are not around to monitor them. It is generally believed
that most of the battery fires were caused by separator failure as a result
of heat build up. The bottoms of some brands of laptops get too warm to hold
on your lap when they are in continuous use. It is a good idea to use the
legs on the bottom of a laptop to allow ambient cooling.

2. The charging may be done while the battery is contained in the device
that it powers. The computer or other device also offers additional
protection by monitoring the charge and reducing or turning the charging
current off. Charging inside the device has the best level of safety. Many
devices do not allow LI batteries to be independently charged because of the
safety issues.

3. The design of the charger must be matched to the battery. The charger
open circuit terminal voltage, filtering, and current regulation must be
designed for optimum charging and safety. The use of off-brand AC adapters
to charge and power a device is as bad as using an off-brand battery. AC
adapters, if not properly matched to the device, can cause damage to the
device and to the battery. They can also fail and catch fire.

For the above reasons, the additional money spent for original equipment
replacements will give the best reliability and safety.
