How do I charge the battery on a 1990 xlh sportster 1200

The voltmeter test provides general indicator of battery condition. Check the voltage of the battery to verify that it is in a 100 per cent fully charged condition. If the open circuit or disconnected voltage reading is below 12.6 V, charge the battery and then recheck the voltage after the battery has set for one to two hours. If the voltage reading is 12.8 V 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 and STATE OF CHARGE FOR AGM BATTERIES IS:

12.8 VDC is 100 per cent

12.6 VDC is 75 per cent

12.3 VDC is 50 per cent

12.0 VDC is 25 per cent

11.8 VDC is 0 per cent



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

Battery Charging Rates/Times (Approximate)



FOR A 19 AMP HOUR DYNA AGM BATTERY



BATTERY STATE OF CHARGE is 12.8 VDC is 100 per cent Charge; Rate of Charge is N/A



BATTERY STATE OF CHARGE is 12.6 VDC is 75 per cent Charge; Rate of Charge at 3 AMP is 1.75 hours at 6 AMP is 50 minutes at 10 AMP is 30 minutes at 20 AMP is 15 minutes



BATTERY STATE OF CHARGE is 12.3 VDC is 50 per cent Charge; Rate of Charge at 3 AMP is 3.5 hours at 6 AMP is 1.75 hours at 10 AMP is 1 hour at 20 AMP is 30 minutes



BATTERY STATE OF CHARGE is 12.0 VDC is 25 per cent Charge; Rate of Charge at 3 AMP is 5 hours at 6 AMP is 2.5 hours at 10 AMP is 1.5 hours at 20 AMP is 45 minutes



BATTERY STATE OF CHARGE is 11.8 VDC is 0 per cent Charge; Rate of Charge at 3 AMP is 6 hours, 40 minutes at 6 AMP is 3 hours, 20 minutes at 10 AMP is 2 hours at 20 AMP is 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 or 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.

How long to charge the ipod to your computer?

Fully charging the battery takes about 4 hours. You can also fast-charge the battery to 80 percent capacity in 1 hour (2 hours for iPod (Click Wheel)). Charging the battery may take longer if you're using iPod as it charges.

Don't know how to charge my new nextbook . . .

THIS FROM SUPPORT SITE> GENERAL 1. How long should I charge my battery and how long does it last?
It takes about 5 hours to charge fully and one charge will last for about 4-10 hours (with default system settings) depending on the work mode where you are. In default system settings and full charge mode, it is about 11 hours of ebook reading, 11 hours of music playback, 9 hours of video playback or 7 hours of web browsing. The time will get shortened if your Next2 handles multi tasks at the same time.
2. How do I charge my Next2 properly?
The device features a DC-IN port for connecting to power or charging battery. To charge the device, connect your device to any standard wall outlet through the DC-IN port using the AC adaptor.

Yellow / green light will not go off when charging

Its likely the batteries will take at least several hours to fully charge, if not more. NiCad batteries are slow charging and usually need 4-6 hours for a full charge. Keep them on longer or even overnight but make sure you remove them in the morning. You will probably find the light turns green after 4-6 hours of charging. If lights stay yellow and green after 12 hours of charging, it may indicate a fault in the battery itself where it will not accept a charge.

Unit will not turn on

Your battery is recharged when connected to your computer. Turn the player off and connect it to your computer via the USB cord. The computer must be turned on. Initial charge should be for 10 hours with subsequent charges 3 to 4 hours for a full charge. A quick charge of 1-1/2 hours will give you a 70 percent charge. A fully charged battery will last up to 15 hours under normal use.
