That completely depends on the battery, my normal battery charging routine on new laptops is i allow the laptop to completely die and then i charge for 24 hours and then let completely die without charging and then charge for 24 hours. repeat this 4 or 5 times. This should give you the best battery life.
Charge time is normally a few hours for laptops tho.
for L ion batterys it is recommended you start a charge between 15% and 20% life remaining.

There is a chance that the charger is broken. Some batteries need to be jump started (charge it for some hours), especially an old battery (the brand new battery but it does not hold charge for a long time)
If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

From what you describe and assuming the new battery was "new", I'd say you have an internal short which is draining the battery over a short period of time. I'd also investigate the accuracy of the battery charge indicator.

I'm assuming you gave the battery a "commissioning charge" when you bought and used it? If not, this is something you should do with all new LI batteries. This bit is reproduced from a website that sells batteries for the Toshiba satellite series:
"2. The new Toshiba Satellite a205-s4777 battery pack needs to be circled
(fully discharged and recharged) three to five times to reach its
3. Toshiba Satellite a205-s4777 battery will undergo
self-discharging when left unused for a long period of time. Thus, it
should always be stored in a fully charged state and kept in a cool, dry
and clean place.
4. It is normal if the new Toshiba Satellite a205-s4777 battery
gets warm when being charged or used. However, please pay special
attention if the battery pack becomes excessively hot. This may indicate
there is a problem with the charging circuit of the electronic device.
Please consult a qualified technician if necessary.
5. To maintain the optimum performance of Toshiba Satellite a205-s4777 battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
6. New batteries are hard to be charged. Sometimes, your
electronic device may indicate a fully charged condition about 10 to 15
minutes when Toshiba Satellite a205-s4777 battery pack is being charged
for the first time. When this happens, remove the battery pack and let
it cool down for about 10 to 15 minutes then repeat the charging
procedure. Sometimes, the new Satellite a205-s4777 battery will
suddenly refuse to be charged. If this happens, a suggested solution is
trying to remove the battery from the device and insert it again. "
The amount of time it takes for your battery to fully charge depends on many factors, like your battery type and operating system. Many newer laptops will charge in 15 to 20 minutes, while others can take a few hours.
When you're charging your battery for the first time, charge it fully before using your laptop. You may have to go through a battery cycle a couple times before your battery begins performing at its maximum capability. To do this, charge your battery fully, let it discharge to about five percent, and then fully charge it again
A brand new battery has to be charged for 8 hours.For any battery related issue, a reset or calibration can be done.Just drain all the charge in the battery by using the laptop only on battery power( ie,with the Charger/Adaptor disconnected).After the comp shuts down due to no power,then charge the battery for 8-10 hours and then check if its fully getting charged or not
At times a BIOS update can fix battery related issues.
Find another battery it says like the one you have is faulty. If you try another known good battery and that fails just like yours then try a know good ac adaptor. If that fails, then its a problem with the motherboard not charging batteries properly but it really does sound like a faulty battery from my experience.
