Recently got a catalogue from ITS London. On the page listing power
tool batteries is the following, verbatim;
----------------------------------------------- Are you confused about
the various battery types available? This information is a guide only,
only batteries suited to your charger and specific tool should be used.

NiCD (Nickel Cadmium). Entry level rechargeable battery which must be
fully discharged before recharging. Failure to do so can reduce
battery life.

That is total ********. *Totally* discharging a Ni-Cad battery - ie one
with more than one cell - is not a good idea. It should simply be charged
when the performance drops off.

NiMH (Nickel Metal Hydride). These batteries have no memory effect
therefore can be 'topped up' or charged at any time without affecting
battery life. NiMH batteries also tend to out perform NiCD batteries in
high drain applications.

Memory effect is an urban myth.

Li-ion (Lithium -ion). The newest battery technology for cordless power
tools, with no memory effect they can be 'topped up' with no effect to
battery life. The main benefit to this battery type is the weight - up
to 40% lighter that NiMH batteries makes these the favourite for power
tools.

-------------------------------------------------

To a battery layman like me, this is a golden nugget of information.
Makes it perfectly clear which is which.

So, first of all, is it by & large all true?

If so, should we steal it for the Wiki?

No.
