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.

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.

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?
