Buying a
rechargable flashlights
The advantage of rechargable flashlights is clear – no more
batteries. But, you need to be aware that they are also more
expensive to purchase than their alkaline powered equivalents.
There are also two different kinds of battery that can power rechargable flashlights, nickel cadmium (Ni-Cd or NiCad) and Ni-Mh.
The difference between the two is that the NiCad batteries need
to be fully discharged before they can be recharged, or they
begin to lose their capacity to hold a charge.
The batteries in
NiMh rechargable flashlights do not suffer from this
problem, but are more expensive. They are usually the ones used
in modern dockable power tools of the kind that can be placed in
a cradle so that they are always on charge.
Of course, there is nothing to stop you buying a regular
flashlight, and using regular NiMh batteries with it – presto,
you have rechargable flashlights! But this approach will not
be as effective as a flashlight that is designed to be
rechargeable from the ground up.
The principle reason that this is the case is that rechargable flashlights use a high intensity bulb which is more
efficient than a standard one, and therefore wastes less charge.
In a regular flashlight this might not be the case, as alkaline
batteries generally supply more power, and therefore the
manufacturer does not have to be as selective over which kind of
bulb to use.
Finally, there is a new variety of rechargable flashlights which
use human mechanical force to keep the charge up, which
alleviates the dependency on electricity.
