How long does it take to charge a 7.2 volt 1100 mah battery using a 9 volt charger?

It depends on the charging rate of the charger. Here's how to calculate it:
Battery capacity divided by the charger's rate = charge time in hours Example: Charging rate = 1000 mah
1100 / 1000 = 1.1 hours
Example: Charging rate = 600 mah
1100 / 600 = 1.83 hours
However the actual output of these adapter chargers is never what is printed on the label so you would need to measure voltage and current to be more accurate.

How do you find out how long it takes to charge a 9.6 1100 mAh battery?
Need to know what the maximum output in amps or mA the battery charger can produce.
How do you jump start a 1999 Yamaha virago 1100?
Is the battery dead? Lost beyond being able to be charged? Well if your not sure, remove battery and clean all connections. All! Then use a quality charger to charge the battery. If it won't take a charge, then you need a new battery. These bikes are hard to push start if not impossiable..with a dead/bad battery. If you really need to just get it started, jump it with your car. Not running. Or a good charger if you have one. Red's.+ black neg. Clean all of your connections first, or you probably won't make the supply to the starter! (hence no start.)
Where is the positive charge located on a Yamaha virago 1100 battery?
The battery is inside abattery box hold by rubber band, the battery box has to be slide out to reach the positive terminal.
What would be the adequate Volts and Amps for a fast charge and for a trickle charge of a 10 V 1100 mAh battery?
WARNING! What battery chemistry are you using? This answer is generic. The precise values and charging profile is very different for different chemistries. If you do not take this into account, you could destroy the battery, and exploding batteries have injured many people. Do not try to fast charge any battery without using the charging profile for your specific battery! Volts are almost irrelevant when charging a battery. As the battery charges, the terminal voltage constantly rises. You simply need to have a high enough voltage to slightly exceed the fully charged voltage of the battery. Most battery chargers, and all fast chargers are configured as current sources. As such, they control the current, and let the voltage fall where it will, at least for the initial charge cycle. Current is usually set at about 1/10th of the capacity for normal charge. For your 1100 mAh battery this would be 110mA. This gives a 14-16 hour time to full charge. 10 volts is an unusual voltage for a lead-acid battery, so I'm guessing yours is a different chemistry. There is really no rule-of-thumb for fast charge that covers all batteries. Fast charging for many chemistries involves ambient and/or cell temperature monitoring and correction, and also detecting minute cell voltage changes as full charge is achieved. Designing a fast charger is not for the novice, sorry.
How do you know if your golf cart batteries are bad?
If you have a manual charger follow the charging instructions. After a full charge, do an On-Charge Voltage Test. Get your volt meter out and set it to 200v dc with the charger on. We will be checking individual battery voltages, start with the #1 battery (where the positive lead goes to the cart) placing the positive lead of the voltmeter on battery positive and the negative lead of the voltmeter on battery negative, move down the line until the last battery. For 36v carts with six 6v batteries we want each battery to read at least 7.0v. For 48v carts with six 8v batteries were looking for at least 9.3v on each battery. Put your safety glasses and safety gloves on. Remove all battery caps. Get your hydrometer out and start with the #1 battery take your sample from each battery cell and write it down. You should have readings of 1100 to 1300, 1100 being close to water and 1300 being acid. Start with the #1 battery. If there is a difference of 50 points or more between cells you have a bad battery. Here is an example of a good battery. 1265 1275 1265 Here is an example of a bad battery: 1265 1175 1265
How long does it take to charge RC car battery?
DO NOT LISTEN TO PEOPLE WHO BLINDLY TELL YOU TO CHARGE YOUR BATTERIES FOR 8 OR 10 HOURS OR OVERNIGHT! THEY ARE WRONG AND UNINFORMED!BATTERIES VARY GREATLY DEPENDING ON A LOT OF FACTORS!! MAKE SURE THAT YOU PLUG EACH BATTERY/CHARGER COMBO INTO THIS EQUATION SO THAT YOU CAN MAKE SURE YOU DON'T OVERCHARGE YOUR BATTERY!!To figure out how long to charge your battery for:(battery capacity (battery's mAh rating)/charger output (mA)) x 1.4(for NiCad batteries, 1.5 for NiMh batteries) = time (in hours).For example:I have an 1100 mAh battery and a charger which outputs at 180mA (it should be written somewhere on the charger - Output= (X) mA - or something like that). It's a NiMh battery so you multiply by 1.5.(1100/180) x 1.5 = 9.146666 hoursNote that the result in decimal, so 9.15 hours is NOT 9 hours and 15 minutes! 0.15 of an hour is approximately one sixth of an hour or ten minutes.Therefore 9.15 hours = 9 hours and 10 mins approximately.Please share this correct information to everyone you can. I have looked on many websites and this information isn't available. Most people just give the regular ignorant blind answer.Thank you for sharing this and for doing your part to educate those out there that love RC/Airsoft/etc... as much as I do!
How do I fix a dying battery on a 1996 Honda Ace 1100?
You will have to replace it. It just might not be able to hold the charge. Also, check the charge rate at the battery, with the rev's up around 2,600 you should get around 14 volts.
Why 1988 1100 Honda motorcycle battery keeps losing charge?
1988 , 1100 ? Anyway, when the bike is running did you run a volt meter on the battery. Should read around 14. something volts. If it reads only the battery like 12.4 volts then most likely the stator is gone. Now what kind of bike was that again?
How many bb's can you shoot per charge on a 9.6 volt 1100 mah airsoft battery?
Here is a quick tip, mAH stands for Milliamps. however many milliamps a battery is rated, that's about how many shots you should be able to get off on a full charge.
