I had a TI - 83 that did the same thing, I stopped using it and eventually bought a TI - 89, it's kind of a bummer, I am not sure what the problem was...

### How do I check if it's my Powakaddy battery or the charger is faulty as the battery on lasted 8 holes and the charger green light was on when fully charged

Batteries have a limited life and depending how old they are and what sort of life they have had depends on the likelihood of whether the battery or batteries are faulty or have a reduced capacity.

Being left discharged or semi-discharged for more than a few days, or a few weeks, operating in a hot climate, overheating during charging or being subjected to inappropriate loads are a few of the things that shorten the life of a battery or reduce it's capacity. A quality traction battery is good for around 500 charge/discharge cycles if it is operated in ideal conditions. Employing a short top-up charge whenever convenient can extend that number many times.

Considering what I have said it could be a good idea to replace the battery considering you need a fair level of reliability - there aren't many short cuts on the golf course.

Testing a battery properly is quite a long process even though there are hi-tech testers that claim to carry out in an instant what used to take a couple of weeks. Testing a wet battery is easier than testing a gel battery.

A digital voltmeter can provide a rule-of-thumb sort of test. Leaving the freshly charged battery to stand for several hours to disperse any surface charge the terminal voltage is then measured. A healthy fully-charged battery has 2.2 volts per cell. That is 13.2 volts for a 12 volt battery. A 12 volt battery that registers 12 volts is only half charged (or faulty) and of a limited practical use.
Less than 12.7 volts and the freshly charged battery needs replacing unless it is used for very light loads. 12.7 volts and above offers varying degrees of serviceability but less than 12.9 volts and the battery is past its prime.

Testing the charger thoroughly can also take some time and expertise but if the battery doesn't become any warmer than a baby's bathwater during charging and the terminal voltage of the battery while the charger is connected doesn't rise above the specifications for the charger, typically around 15 volts depending on charger type, the charger would seem to be doing the job.

### How many hours battery life for the Acer Aspire one KAV10 netbook when fully charged

The Acer Aspire One KAV10 Netbook comes with a 3 cell battery. With the 3-cell battery you're going to get less than three hours of run time.
If you need more battery life, you should consider upgrading to a 6, 9 or even 12 cell battery, depending on your needs.

### 1995 dodge stratus keeps going dead in driveway. I jump it off and let it run 15 mins to charge battery up. Turn off and crank right up, but the next day it is dead again.

With engine running used a voltmeter and check voltage at battery, you will be checking alternator out put voltage, should have a reading of no less then 13.0 volts, if less bad alternator, the reason it keeps going dead is that the car is using the battery to run it .till the battery has no more power, then you jump it and the battery is charge up again and will run again till it goes dead again.

### I was sitting in the car for a few hours listening to the radio and turning the car on and off several times during that time. when i went to leave the battery was dead. got a jump and drove home, about 20...

If the battery was run down enough 20 minutes of dring will not recharge it. It should go on a battery charger and then the battery condition checked. Just sitting and using the battery to play the radio is not a good idea. That is very hard on the battery and will shorten the life severly. If the battery was still the original I'd just replace the battery for a battery that old too much damage would have been done to even chance using it if would last it will not be long.

### Battery life less than 12 hours; Wifi says "UNABLE TO CONNECT"

This is a really good article that will take you step by step through the settings that will best optimize your battery life. And if this doesn't help you should make an appointment at your local Apple store, they are always very helpful (at least in my experience).

### Battery life seems fairly short. How long should

Hi,
In most laptops the standard idle life is around 3 - 4 hours. The drain from the internet can cut this down to between 1 - 1 and a half hours. Using games is around the same or less than what the internet takes and if your using an office application it is around 3 - 4 hours.
Using the laptop for power hungry multitasking will reduce battery life dramatically.

Regards.

### My palm centro started going dead with a low battery signal literally overnight. I replaced the battery with a new one, and it still won't stay charged longer than 6 hours. Also the phone is now running...

I've had a Centro for 3 months and its such a let-down. Not only does the other caller find that my voice comes and goes randomly during calls but, like you, the battery started playing-up.

You'll find that a hard reset will bring the battery life back up. Hard reset clears EVERYTHING, so backup. To hard reset, remove and replace the battery while holding down the red, drop-call button until you are prompted to hard reset.

You'll find the battery life is bertter again, at least for a couple weeks...

### Utility LED flashing green/red

Seems like your Battery is very low. Try charging the battery for a few hours. If the problem persists, it maybe the time to get a new battery.
Like all batteries, UPS Batteries (that store electricity and let s you use it in case of a power failure) have a limited life. This life is averaged to be around 2 years. So in case your UPS has been in use for approximately that much amount of time, the battery is in a near death situation.

For instructions regarding replacing the battery, please refer to your UPS Manual.

PS: Also, I have noticed this kind of behavior when the UPS is connected to a socket powered by an Inverter. This kind of behavior is observed when the Inverter battery is running low.
