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.

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.

18v 12 cordless trimmer/edger. Why won't it start?


the trimmers switch may be faulty.

CHARGING THE BATTERY PACK
Battery packs for this tool are shipped in a low charge condition
to prevent possible problems. Therefore, you should
charge them until the green LED on the front of the charger
comes on.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged.
CHARGING A COOL BATTERY PACK
See Figure 3.
If battery pack is within normal temperature range, the red
LED on charger will come on.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack and
charger to your nearest Ryobi Authorized Service Center for
electrical check.
n Charge the battery pack only with the charger provided.
n Make sure the power supply is normal household
voltage, 120 volts, 60 Hz, AC only.
n Connect the charger to the power supply.
n Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
n Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
n Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
n Red LED should remain on for approximately 1 hour
then the green LED will come on. Green LED on
indicates battery pack is fully charged and charger is
in maintenance charge mode.
NOTE: The green LED will remain on until the
battery pack is removed from the charger or charger is
disconnected from the power supply.
n If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.
n The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
n Do not place the charger and battery pack in an area of
extreme heat or cold. They will work best at normal room
temperature.
NOTE: The charger and battery pack should be placed
in a location where the temperature is more than 50°F
but less than 100°F.
n When batteries become fully charged, unplug the
charger from power supply and remove the battery
pack.

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.
