MY Battery does not go all day,IS IT NORMAL?

Using the 5/5/90 rule, your radio should last approx. 8-10 hours on a charge (exceptions do exist). 5/5/90 = 5% of the time transmit, 5% of the time receiving, 90% of the time standby. If you use your radio more often, your battery will run down quicker.
You may have a bad battery or poor charging habits. When you get a new battery you should charge it on a standard rate charger for 12-16 hours to fully activate the chemical in the battery. Once you have done this each subsequent charge should be after you have used your radio 8-10 hours or ran the battery down. Do not get in the habit of putting the battery on the charger when coming in for lunch or after using the radio only a few hours. This will cause air bubbles in the chemical, also known as "memory".
If your battery is more than 18-24 months old, you need to replace it.
