Nowhere can I find the current draw of a LED Flashlight. The manufacturer deliberately leaves this vital information out in their sales brochure.
Not only that, the construction is such that standard meter probes cannot be used to make a measurement. Inserting a spade fork in the battery pack shows a current draw of .140 A (140ma) at 20V. For a 1.5AH battery pack, this works out to 10 hours light time. It looks like the battery powered tools are sold without batteries because the Lithium battery pack cost 2-3 times what the tool is worth. Charge times are as yet unknown and are rarely published.
My guess is that the battery life decreases slightly after every charge...by how much is, again unknown. This confirms my belief that battery technology has not kept pace with other technological developments...More to follow.
