Hey all,
So many years ago, my father picked up a Dyson DC16 handheld vacuum, powered by a lithium-ion battery pack.
Ever since like the third month in basically, though, the thing could not hold a charge. Its kept plugged into its charging base, as its meant to be, and the battery indicator lights on the unit show that it is completely charged. However, when you try to use it and pull the trigger, it comes to life as normal, but only stays working for 2-4 seconds, before quickly tapering off in power, and then stopping altogether. Pull the trigger again, and repeat the process. You can typically pull the trigger to do this 4-second "burst-vacuuming" about 10 times or so before each burst becomes successively less powerful.
Even stranger still, sometimes, by pure chance or luck, one pull of the trigger out of the 10 will last longer than the 4 second mark, seemingly never ending, though the power and loudness drops with every passing second until it sounds so weak that you WANT to let it rest.
What I'm wondering is: is this a battery problem, or a machine problem, and is there any way to figure it out if all I have at my disposal is a soldering station and a multimeter? I have no battery capacity or discharge testing machine so I can't tell if the cells are fried or something, unless there's a way to do that with a multimeter. My dad just doesn't want to purchase a new battery only to find out it was never the battery in the first place.
Any help is greatly appreciated, cheers.
