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.

The car is not holdong a charge. I replaced the Battery about a year ago. Today I replaced the alternator. I used jumper cables it ran for about 20 minutes and then died again. All the wires look good. Any...


FIRST, YOU MAKE SURE THE BATTERY IS FULLY CHARGED.. A GOOD BATTERY WILL GO FOR 12 HOURS EVEN IF THE ALTERNATOR IS NOT WORKING.. SECOND YOU TURN THE CAR ON.. ONCE THE CAR IS ON. YOU DISCONECT THE BATTERY,, IF THE ALTERNATOR IS GOOD , THE CAR SHOULD REMAIN ON WITHOUT A BATTERY.. IF IT SHUTS DOWN , YOU HAVE A BAD ALTERNATOR OR THE WIRING IS WRONG ONE OF THE TWO.. SHORTS ON YOUR WIRING CAN CAUSE THE BATTERY TO LOOSE POWER.. BUT NOT THAT FAST. BECAUSE IF THE SHORT WAS TO SERIOUS.. YOUR WIRING WOULD BE BURNED.. COMPLETELY..
IF THE ALTERNATOR IS OKAY,, REPLACE YOUR BATTERY,, MOST OF THE TIME BATTERIES GO BAD EASY WITH ANY LITTLE PROBLEM THE CELLS BURNOUT AND THEY DONT HOLD A CHARGE EVEN IF FULLY CHARGED THEY WILL LOOSE POWER IMMEDIATELY .. I THINK THAT IS YOUR PROBLEM.. SINCE IT ONLY LASTED LIKE 20 MINUTES.

try this won't hurt and is simple Disconnect your battery....both the positive and negative cables. Let it sit for about 15-20 minutes and then short the cables together with a piece of metal like a combination wrench, NOT the battery terminals, just the pos and neg cables. After you have shorted the cables you can reconnect the battery and the cluster may now come back to life and vehicle start. You are basically rebooting the car's computer doing this.
hope this helps.

That is a known issue with that model of computer. The battery is not very good. I recommend taking it to a certified repair technician for an expanded battery.
My cousin has one and using windows 7 he gets about 20 to 30 minutes of battery life on average.

Inspiron runs on ac power but not battery


Sounds like you have a faulty ac adapter or jack on the laptop and its not charging the battery fully. More like a trickle charge. I would recommend leaving the laptop on default power settings or the best power settings and see if their is a differance in life or either shutdown the laptop and let it charge until the light shows fully charged.

I'm not sure of your charging regiem but it is possible that you hav not let the batteries become disscharged before they back on the charger, short cycling particular batteries gives them a memory and reduces their life significantly. Most rechargeable batteries have a life of so many cycles, just say its 100 cycles. If you put on charge when battery is only down to 80% and charge it up this counts as 1 cycle. Therefore your battery life would be reduced to 20% of what its capable of. This is only true if short cycling the chargeing of the battery is frequent. Not knowing exactly what your charging habits are or the age of them makes it a guess from me. It otherwise might be a fault in your charging circuit which would require specialist diagnosis.
