2 of them drained, 2 half full. probably.

i use them for my digital camera. the camera says they are
empty. i put 2 of them in my discman. empty. i put 2 other
ones in: half full.

q:

how many combinations of all four batteries must i put into
the discman (or any other device) to completely drain them
all?

i think

1-2
1-3
1-4

2-3
2-4

3-4

right?

these numbers being fictional numbers for battery 1 to 4.

so 1 and 2, 1 and 3 etc.

i cant take photos when the batteries are empty..

they need to be 100% depleted before i can recharge them.

if 2 are empty, and 2 are not, the charger will fuck up.
it's also bad for the camera..

radio is on.

label the batteries 1234

run 1+2 till depleted.
run 3+4 till depleted.
run 1+3 till depleted.
run 2+4 till depleted.
run 1+4 till depleted.
run 2+3 till depleted.

There... six different possible combinations

Play them in the cd player while you are doing something, or
better, run them through flashlights that don't get turned
off untill they are dead.

btw, most batteries are connected in series, which means
they both drain at the same rate..

so really, if you run 1+2 till empty, and 3+4 until empty,
then 1+4 will also be empty, along with 3+2..

Most modern discmen can go forever without dying. My
mp3discman can go for a month on a single battery before it
starts to show signs of dying.

interesting. it makes sense, but i'll double test this
series just in case.

taxi: the discman isnt supposed to die though :P

but yeah with a good set of batteries it lasts ages.

You obviously aren't hitting it hard enough...

how are you going to keep it in line when it gets older and
more dissillusioned?

it's at least a few years old and plays 99% of all my cds,
even the scratched ones. it deserves a big thank you.

this one, except in transparent blue and shockproof not
jogproof.
