Default Flashlight temptation / types of battery packs

How'd they do it? Why didn't they go ahead and make it a two D cell
flashlight? It is a two cell flashlight with half the capacity not
used.


Is the point of this so you can waterproof it? Surely you now have a
USB socket full of water?

I'll just take the batteries out and charge them thanks, it also means I
can take spares on a trip without bothering with a charger.


I've been tempted by battery packs. However, I
also remember taking apart square Duracell 6 volt
lantern batteries. The one or two I've done have
D cells inside, with a cardboard spacer and some
metal to conduct electricity. I've also found they
usually have one dead cell, and three which work
fine. Lot to be said for loose cells.

I've recently bought a couple of 6 AA battery packs
for my amateur radio handi talkie. I can get lithium
ion rechargable packs. But, I do like to keep the
options open. I can stop by the store and buy AA cells
easier than finding a lithium ion battery pack.

It's unlikely I'll ever be in a situation where I
have my one D cell light, and one working D cell.
But, then, I like to wonder and dream.
