Try a different known working outlet just to make sure that its not putting out to much voltage and making the ac adapter to hot.

You also may want to try a different battery to make sure the battery isn't affecting the ac adapter.

If you do this and you are still having this problem then it could be a problem with the cells inside of the battery and you'll have to replace the ac adapter.

    Since none of them worked your dc jack on your motherboard may have bad solder connections.

    The solder points on the bottom of the dc jack probably need to be resoldered so that way the connection is strong enough and it can continously charge without having to take out the adapter.

    A repair shop should do this for you, bring it to a few of them and get a quote.

Is it best to keep my scooter on charge all the time or what


Lead acid or deep cycle gel batteries are best kept on trickle charge.

Take care of your batteries
How do I get the most life out of my new batteries?
To maximise the life of your batteries, it is best to complete a full charge for the first 1015 times that you use your scooter. This simply means however far you travel, do not just top-up for a short while, but complete the full charge cycle every time. Your batteries will not work at their best until this process has been carried out and will prolong power and performance. You will find the distance your scooter can travel will gradually increase over its first few weeks as your batteries reach optimum efficiency.
When is it best to charge my batteries?
After 10-15 cycles have been completed, a normal charging routine can be adopted
  • Depending on the capacity of the batteries, the charge time can vary up to a maximum of 16 hours
  • The charger will automatically shut down when the batteries are fully charged, so you do not have to worry about switching it off. This is ideal for overnight charging.
  • Whenever possible try to avoid interrupting a charge cycle. It is always best to complete a full charge cycle as excessive short term charging is detrimental to battery life.
  • For the very best results and to maximise battery life, charge fully before and after use.
  • Please refer to charger indicator lights for battery status.

How do I store and maintain my batteries?
  • If your scooter will not be used for a while or is being stored, make sure the batteries are fully charged first.
  • If your scooter is not being used, make sure the batteries receive a refresher charge every 14 weeks. Alternatively if you are planning not to use your scooter for over 6 weeks, fully charge your batteries and then disconnect.
  • Fully charge the batteries before re-use.
  • Never leave the batteries in a discharged state.
  • Avoid damp, hot or cold extremes when storing your scooter.
  • Batteries are totally sealed and do not require any maintenance apart from charging.

Charging
1.Switch off your scooter and remove key.
2.Plug charger into scooter charge socket.
3.Push charger plug into wall socket and switch socket on.
4.There will be a light sequence on the charger but as all chargers are different, refer to charger instructions.
5.Most scooters will have an inhibit mode which will shut down all the scooters electrics while the charger is plugged in.
6.Only use the charger supplied with your scooter.
7.Do not smoke or use a ***** flame while batteries are being charged.
8.Do not leave charger plugged into your scooter when the charger is switched off as this may discharge your batteries.
9.For a complete charge do not switch off, unplug or interrupt the charge cycle until it is complete.
It is worth considering that in extreme cold weather the time your batteries take to charge can increase by up to 20%. The range of your scooter will also vary based on weather conditions. Also when your batteries reach the end of their useful life, you will find that charging time will become much shorter. The amount of charge the batteries can hold will become less and less as will your scooter range until ultimately they become unusable.

Charger seems to have both red and green lites flashing at the same time no sequence and both batteries connected read 4.0 VDC, are these chargers repariable or throw aways


Your manual is here. The section on charging states, that green blinking means your battery is fully charged but blinking red means that your charger is faulty. I would say repairable.

1. Plug the female connector of the AC power cord (supplied) to the AC receptacle on the charger and plug in the male connector on the AC power cord into the wall outlet.

2. The On/Off LED indicator is blinking RED, this is abnormal. Unplug AC power cord from the on-board battery charger and wall outlet. Charger may need to be replaced. Contact an Invacare dealer or qualified technician.

3. When the On/Off LED indicator light is Off, charger is Off.

4. When the Charge LED indicator light is YELLOW, the batteries are charging.

5. When the Charge LED indicator light is solid GREEN, the batteries are fully charged (as their condition will allow).

6. When charging is complete, unplug the male connector of the AC power cord from the wall outlet and then unplug the female connector of the AC power cord from the AC receptacle on the charger.

Ryobi charger model # 140295003 has a red and yellow light. When charging red light is on what does the yellow light mean? Also how long should the battery be left in the charger?


Completely wrong. Quoting from the user's manual:

"The charge indicator light (LED), located on the charg- ing stand, will light up red and glow when the char- ger is properly connected to power supply. This light indicates the charger is operating properly. It will remain on until battery pack is removed from charging stand or charger is disconnected from power supply.

After normal usage, 3 hours or less of charging time is required to fully recharge battery pack.

If both red and orange LED indicators glow, the battery pack is deeply or completely discharged, and 6 hours or longer of charging time is required to fully recharge battery pack.

Note: If charger does not charge battery pack or orange LED continues to glow after more than 30 minutes of charging, return battery pack and charging assembly to your nearest Ryobi Authorized Service Center for electrical check."

So to summarize: red = charging. orange (yellow) = fully discharged battery. orange after 30 minutes - bad battery or bad charger.

Iphone 3g proper charging


Once you purchase the iphone,dont use it yet.Instead of using it right away,kindly charge your IPhone with the wall charger for 3 hrs.Please dont use the Iphone while charging.Kindly check always if the battery is full.Once its fully charged then that's the time that you can use the iPhone. Once fully charged, let the iPhone's battery fully drain.Please keep the iPhone off for 2 hours.Fully charge your iPhone and allow the battery to rest in the fully charged state for two hours. (You may use your iPhone during this time as long as the iPhone is plugged in).Repeat the third and fourth step a maximum of three times if you feel your battery indicator is inaccurate.

Here are some tips for your everyday charging for your IPhone:
#1 - Charge your iPhone throughout the day when available. Charge EVERY night, regardless of charge level. This will keep your battery active, which is healthy for the iPhone's battery.
#2 - Use a wall charger or car charger w/ rated output 5V 1A. Computer chargers might not charge when the computer is in standby mode.
#3 - You cannot overcharge your iPhone. You don't need to disconnect the iPhone from the charger after it's done charging. Once fully charged, the iPhone will run strictly off of AC power and will not damage the battery.
#4 - Every two months, make sure you fully charge and fully drain the battery, in one cycle. This calibrates your battery indicator. If you fail to do this, your indicator will become inaccurate. Calibrating your battery does not improve battery life.
#5 - If you ever need to store your iPhone for any reason, make sure your battery is stored @ roughly 50% and in a cool environment.
#6 - Always charge your iPhone out of its case (assuming you can easily remove the case). Charging your iPhone inside your case will make the iPhone hotter, which is bad for the battery.
#7 - Charge your iPhone in a cool location. Charging your iPhone in a cool environment has a tremendous impact on your battery's lifespan. The colder the location you use to charge, the more charging cycles you can complete without your battery deteriorating. Avoid charging in direct sunlight.
#8 - Use properly rated chargers. Using chargers that are not properly rated will have a huge impact on your battery's lifespan. Make sure your car charger has the same rating as the official Apple charger.
The official Apple wall charger is rated as follows:
Input: 100 240V ~ 50/60 Hz 1.0A
Output: 5V 1A
Thanks!

Hi i have an experia ant the littli led light on the top stays on red all the time


Hi.

The little red light means your battery requires charging.

Plug in the charger and allow it to charge.
It should change colour to orange when it has over 15% charge in it and then turns green when it is 90% charged.

If it still stays red dispite being fully charged. Try removing the battery for a few seconds and then replace it again.

I hope this helps.
If your phone is fully charged and it still has a red light, then take it back to the shop you acquired it and get a replacement.
It means you have a hardware fault.

Bought a new battery (larger one) and it will only charge for 1 second?


Check if the battery is already fully charged. If it is, the charger will stop charging when battery is 100% charged.

You can check this by unplugging the charger cord from the laptop. If the battery is not fully charged, plug in the charger cord into the laptop again, start the computer and enter the BIOS. In the BIOS, look to see if you have a "battery check" and start it. This will test the charging and discharging cycles of the battery.

My DC16 will start and then stop. I have to take


My DC16 also had charging problems. I called Dyson and they sent a new charger. The old charger only produced 23.6 volts DC, not the rated 28 volts DC. The new charger has a thicker round wire and produces 28.1 volts DC. Put a volt meter on your charger terminals and see if it is producing enough voltage to fully charge the battery, 28 volt DC. If not you need a new charger.

Battery problems


You need to replace your battery.  When you do follow these steps to preserve battery life.
1.  Fully charge battery for 24 hours 2.  Make sure that you use the phone without charging it until the phone tells you the battery is low. 3. Fully charge the battery until it reaches full again.
The reason your battery is failing to hold a charge is a problem call battery memory.  The less power that you use off the battery the less capacity the battery has.

Battery charging


All lead-acid batteries contain highly corrosive sulfuric acid, generate explosive gases and have warning labels which should be observed closely. For best results, charge the battery as soon as you know it is discharged. To charge your battery, follow these steps and important safety tips: Before Charging: 1) Read the charger manufacturer's instructions. 2) Put on protective eyewear, rubber gloves, work clothes and remove all jewelry. 3) Place the battery in a well ventilated area. 4) Don't charge a frozen battery. Allow the battery to warm to about 60?F before charging. 5) If applicable, remove the vent caps and check the battery's water level and, if low, add distilled water to cover the tops of the plates. Do not overfill. 6) To determine if the battery needs to be charged, test it with a hydrometer to determine its specific gravity and/or with a voltmeter to determine its state of charge. 7) If applicable, reinstall vent caps before charging. 8) While the charger is unplugged, connect the leads to the proper battery terminals. Note: For side-post and studded batteries, we recommend that you use adapters to insure adequate contact. For additional information regarding adapters, contact Interstate Batteries. 9) Set the charger to the proper settings for your battery, e.g. 6 volts vs. 12 volts, low-maintenance vs. sealed, standard automotive vs. deep cycle. 10) Plug in and turn on the charger. 11) Don't wiggle the connections to check contact while the charger is turned on or plugged in. 12) Choose the lowest amperage setting initially. Once the charger is on and the battery is charging, you may want to choose a higher amp setting to reduce charge time. During Charging: 1) Keep the vent caps on. 2) Don't allow smoking, open flames or sparks near the battery. 3) Don't allow the battery to become hot to the touch. After Charging: 1) Immediately after the battery is fully charged, turn off and unplug the charger. Continuing to charge a fully charged battery will severely damage the internal plates and shorten battery life. 2) Disconnect the leads from the battery.
