Gel cell batteries usually are good for 3 to 5 years and from your description, it sounds like the battery is not recharging properly. They will indicate a full charge but in reality, do not have the stored power to operate the device. Check for replacement batteries at your local burgular alarm shop or buy online BUT make sure to match the voltage and AH (amp hours) ratings.

Insert the tip of your fingernail in the groove, and open the cover.
  1. Connect the supplied micro-USB cable to the headset, and then connect the other end to a computer.
Make sure that you connect the plug of the micro-USB cable in the direction as shown in the illustration below.
Charging starts when the headset and the computer are connected.
Make sure that the indicator (red) lights up. Charging is completed in about 6 hours* and the indicator (red) goes off automatically.
*Time required to charge the empty battery to its full capacity
Notes
  • If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. In this case, do not disconnect the micro-USB cable from the headset and wait until the indicator (red) lights up.
  • When you close the cover of the micro-USB port after charging the battery, push the catch at the edge (the round part) of the cover into the port compartment.

Red light normally means that the battery needs charging. The green flashing light can mean the battery is charging or has charged, and the same with the solid green light. Green in this case is good.

Charge the unit overnight and see what the indicator state is. It should not take more than 8 hours of charging for a Li-ion battery. Once you know what the full state light looks at, then you can tell what the charging indicator looks like.

In all cases, ensure you are using the proper charger with the unit.

The main unit beeps every 30 seconds


This is battery related. On top of your unit is a battery pack with three colored led lights. You can tell what is going on by looking at these. This information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing green LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.

Battery indicator?


Hi there.
Sounds like the battery could be faulty.
The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective.

Good luck

Upon power up, 3 red LEDs flashing rapidly continously, no power.


The control systems on power mobility equipment have a "prevent" circuit that immobilizes the equipment while it is plugged into a charger, so folks won't take off with it plugged into the wall outlet. When you turn it on when plugged into a charger, the display will flash constantly, or sweep constantly, depending on the manufacturer. This is normal. Your off-board charger should have a red light to indicate power to the charger, and another light for the charge status. Yellowish means it is charging, when it turns green, you are fully charged. If the status light is green all the time, that is an indication that the charger is not functioning properly, or that the batteries are below a chargeable state. Check charger output, which should be 26-28 volts dc, and each battery should show at least a 12 volt reading, but around 13.5 volts with a full charge. If one or both of the batteries drops below 12 volts after a short period of time, it's time for a fresh pair. Fully charge new ones before using the chair.

Power problem


Seeing as you notice that your battery life is half, this most likely means your battery is no longer able to hold a charge, or a full charge. It could also mean the battery is defective.
If your laptop is still under warranty, the manufacturer may replace it. If not, you'll have to buy a new battery, unless you always keep it plugged in anyways.

From the manual:

"Attach the barrel tip of the AC Charging Adapter to the AC Charging port of the POWER TO GO® and plug the standard two-prong plug into an appropriate, functioning 120 volt AC outlet. The red Battery Status LED indicator will flash, indicating a proper connection has been made and the unit is charging. The green Battery Status LED indicators will gradually light as the charge level rises. The POWER TO GO® must be charged for approximately 11-17 hours prior to first use. All Battery Status LED indicators will be lit solid (the red indicator will stop flashing) when the unit is fully charged.
