This is normal when your battery is slightly low on charge.
Maybe your gauge is a little sensitive.
If your car starts and the gauge doesn't go into the red too long, you are fine.

OK Try This Again; Check Battery Voltage Without the Engine Running, should show 11.5v to 12.5v, With the Engine Running at Idle should show 12.8v to 13.7v, With the Tester on bring the RPMs up to 2,000/3,000, What Does the Tester Show Now? If 14.0v or Higher your Alternator is Shorting Under Load, Replace It!
NOTE; Check All Wires and Grounds at Battery & Alternator! Also Connections at the gage.

When you accelerate, the rpm's rise and the alternator charges up to it's peak output which is usually around 14 amps. The easiest way to solve your problem is to probably take your car to a an auto parts house that offers free diagnostic. I know Autozone does battery testing. If the battery is dead, then the alternator is not charging it. If the battery is new, then dies the alternator is bad. The only time a battery usually goes bad is due to battery age and lack of maintenance..ie...adding water on an unsealed battery. If you have anyone that has a dc volt meter, have them check the output of the alternator and the battery. Good luck. Alternators can vary greatly in price as do batteries.

In most cases your accelerating would cause a gauge to increase just a bit and visa verse. But if your experiencing a large amount of volt out put when accelerating then your alternators regulator needs replaced. And now days those are installed inside of the alternator.

You don't say anything about the battery giving you problems. Was it dead or what? Is the only problem the voltage indicator ? If that is it, It doesn't appear you have a problem. The indicator shows what the voltage is and it will change. If I have missed what the problem is, please explain it more fully.
