You have 3 options:
1. You could do a search under the part number of the machine for a parts break out diagram.
2. Open the vacuum, and do a search for the battery when you see the part number on the old battery.
3. Call the manufacturer for assistance.

Yes if you can get one

I had the same issue, then i just found the manual, in charging part, it says:"The charging indicator will be lit as long as the
appliance is connected to the plugged-in
charger."
Also it says:"While charging, the charger may get warm, this is
perfectly normal and safe. It can remain on
charge indefinitely without damage or danger. It
is not possible to "overcharge" the battery cells
with the charger provided"

What model number is this. Black and Decker does not make a 16.8 to my knowledge, so a model number would be helpful.

Response by small6363 was right on target. All the reviews and comments I had read up to this point for my Dustbuster CHV9600 indicated the battery could not be replaced. I am so glad this link was here.I have ordered the part and will follow the other posters' cautions about reassembling the product. I could not be happier as I could not find the model anymore and it is my favorite purple color. Thanks again small6363. You are a life saver.

This unit is recharged using any household 120v outlet. Remove the rubber cap from the recharge port on the top of the unit. Plug the barrel end of the adapter cord into this port and then the put the adapter into the wall outlet. Make sure the power switch is in the off position. To check the charge level push the button to the left of the 3 indicator lights. When the green LED lights up, the unit is fully charged, (yellow is moderate charge and red is minimum charge).
Try to charge the unit from the minimum (red) charge level to maintain the maximum battery life and use of the product.
If you have misplaced the manual I am providing a link to it from Black and Decker's site.

how long do you charge the batteries for the S300 Scum Buster

Hi I know what you mean! My B&D dust buster used to do this too. The hi power boost means that it can only be used for a limited amount of time. Due to the age of the dust buster though its a sign that the battery is on its way out and regardless of whether or how long its been used or not used, batteries can lose power regardless.
Try to let the dust buster completely lose power and then charge it up for its initial burn in period of 14 hours. Also clean the connection metal strips or hole with a dry cotton bud incase there's any static or dust. Then see if it lasts longer. If the turbo mode or speed 2 is still short, then the battery is dying out.
I don't know where you are but in the UK its hard to get battery replacements for B&D products. You could check your local seller where you are if they have battery replacements but at the cost of current dustbusters it may make more economic sense to consider buying a new dustbuster.
