    usually the CPU fan has failed if the PC shuts down.

    Is the battery pack hot?

    Have you tried removing it and powering up via wall charger only??

Yeah, computer batteries though they look fancy, they just have fancy covers. If you were to open one you'd find a bunch of what look to be perfectly ordinary rechargeable batteries all soldered together in trays. Lots of them are made with AA and AAA rechargeables. Just like any rechargeable battery they are only good for about 300 cycles before they start to loose some of their capacity. Just like a cell phone battery they need to be replaced periodically usually every 2.5 to 3 years. Your computer doesn't care who made your battery and there are several much less expensive alternatives to your name brand battery. Take the model number off of your battery and google it you'll find replacement batteries for much less. Just make sure your computer is listed in the 'compatable with' listing on the site and buy from a seller with a good rating.

If it is orginal battery it is probably dead. You can buy replacements nowdays that can last 4-6 hours. I suggest NOT buying a used one. You can check ebay stores for new ones though.

Dead battery 1990 xlh sportster 1200


The voltmeter test provides a general indicatorof battery condition. Check the voltage of the battery to verify that it is in a 100% fully charged condition. If the open circuit (disconnected) voltage reading is below 12.6V, charge the battery and then recheck the voltage after the battery has set for one to two hours. If the voltage reading is 12.8V or above, perform the load test described below.



The load test measures battery performance under full current load and is the best indicator of battery condition. Load testing a battery tat is not FULLY CHARGED i.e. at 12.8 VDC can permanently damage it. Fully charge it first and then let it stand for at least an hour before the load test is done. You also need a load tester. AND you should know how to perform a load test. Often the best way to load test a battery will be to take it to a battery shop and have it done there.



VOLTAGE (OCV) STATE OF CHARGE FOR AGM BATTERIES IS:

12.8 VDC = 100%

12.6 VDC = 75%

12.3 VDC = 50%

12.0 VDC = 25%

11.8 VDC = 0%



COLD CRANKING AMPERAGE (CCA) for a DYNA battery is 270













19 AMP HOUR BATTERY =



BATTERY STATE OF CHARGE = 12.8 VDC = 100% Charge; Rate of Charge = N/A



BATTERY STATE OF CHARGE = 12.6 VDC = 75% Charge; Rate of Charge @ 3 AMP = 1.75 hours @ 6 AMP = 50 minutes @ 10 AMP = 30 minutes @ 20 AMP = 15 minutes



BATTERY STATE OF CHARGE = 12.3 VDC = 50% Charge; Rate of Charge @ 3 AMP = 3.5 hours @ 6 AMP = 1.75 hours @!10 AMP = 1 hour @ 20 AMP = 30 minutes



BATTERY STATE OF CHARGE = 12.0 VDC = 25% Charge; Rate of Charge @ 3 AMP = 5 hours @ 6 AMP = 2.5 hours @ 10 AMP = 1.5 hours @ 20 AMP = 45 minutes



BATTERY STATE OF CHARGE = 11.8 VDC = 0% Charge; Rate of Charge @ 3 AMP = 6 hours, 40 minutes @ 6 AMP = 3 hours, 20 minutes @ 10 AMP = 2 hours @ 20 AMP = 1 hour





The figures listed above assume that the battery is charging at room temperature. If warmer than room temperature, use a slightly shorter charging time. If colder, use a slightly longer charging time.



The use of constant current chargers to charge maintenance-free batteries is not recommended. Any overcharge

will cause dry-out and premature battery failure. If a constant current charger is the only type available, do not exceed the charge times listed above and do not continue charging the battery if it gets hot. When charging, never exceed 15 volts for more than 30 minutes.



If the battery gets hotter than 110 degrees F. (43 degrees C) during charging, discontinue charger and allow the battery to cool. Overheating may result in plate distortion, internal shorting, dry out and/or other damage.

My battery backup is only 10-20 minutes only,


I think what you are asking is why does your battery only last 10 - 20 minutes.
The answer is that you need a new battery. And here's a suggestion for you: When you install a new battery, let it run completely down 3 or 4 times to get it to accept a full charge. Thereafter, let it run down once a month to give the battery maximum life. Doesn't matter what the "experts" say--just do that.
Modern batteries are not supposed to have a "memory" but I've found that it's best to exercise a little preventive care.
Also--rechargeable batteries have a limited life.
