I had a similar problem when I bought an after market 2Ah battery. Would stay solid red for a few seconds then flash red. I believe my problem was that the battery had gone into "sleep mode" I.e. it was discharged to the point that it "sleeps" in order to protect itself. So......I simply attached a domestic DC multi adapter to the terminals on the battery that are marked + and - (the 2 outside terminals on a DC16 Dyson battery). Switched on the DC adapter for around 10mins and this was enough to "wake" the battery. It now charges as normal attached to the DC16 in the Dyson charge mount.

SOURCE: my dyson dc16 is not holding a charge
I had that SAME problem! It ran for just a few seconds after having a full charge. Cleaned the filters, tried everything. Just needed a new battery...
My Dyson DC16 hand vac's battery finally went out at 4 years, which is about right. I didn't want to pay Dyson $75.00 for a new one!
I found a good deal on ebay for new batteries that didn't break the bank!
That's all it needed.
It's good to have my hand vacuum back! I missed it!
Rock on Dyson.......
SOURCE: Hello, what is the significance
yes the reason the green and red light were flashing the way they are is because its a warning to you that the battery is either no longer good or there is problems with your wireing. Also those vaccumes were designed to not charge when there to cold or to hot as a saftey issue.
