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.

I can leave it plugged in for 24 hours and not have a full charge. Is this the batteries or the on board charger


There are a few things to consider with this type of problem.

How old are the batteries. When did you last have them tested. Is the charger output ok on load (test with an amp clamp type meter). is the charger the correct one for these batteries, small output chargers take longer to charge big batteries. Are all connection tight on batteries and anything to do with the charging circuit. Plug and socket type connection do fail on poor connections. Check voltage on batteries when on charge and off charge to see if the charger voltage is getting through to the batteries.

The charger is defective. I would not try to charge it externally because if you charge it with a higher rate of current (amperage) than the original charger, it could explode or leak.

My Kocaso M1062 will not take a charge and says connect charger.


The power Cell (Battery) no longer accepts a charge. The exception is if the AC/DC charging adapter has failed. See if you have a similar power charger around the house. Look for the same type of male pin and proper DC or AC Voltage plus Amps as listed on the current Tablet Charger. Never leave chargers in the electrical outlet alone as they can be damaged by surge power. Try another charger and if that fails also, the power cell in the tablet needs replacing.

Sounds like one or both of the batteries has a high internal resistance. Bad batteries, perhaps? Have you LOAD tested or tested for internal resistance? Could be why charger is shutting off so soon.
Voltage isn't the only test for these types of batteries.

Screen is black all the time, can't turn phone on or off


1) Is your charger / adapter working OK ?
Most of the time, an adatper or charger contains a red or green LED, showing it's active, when inserted in the wall-outlet (110 / 240 V AC). In some cases, this LED will emit light, only when the mobile phone is connected.
If this doesn't happen, you might consider buying a new(er) charger for your mobile phone.

2) Is battery charged ?
No further discussion / c;arification needed.

3) Does phone contain an old(er) battery ?
If the mobile phone is used for a longer time or used intensely, the battery might be "worn out". A battery is able to be charged, but will show it's limits, because of it's maximum usage. With this I mean, they can be charged a maximum amount of times. If you even use a quick-charger, the battery may suffer more, resulting in a less longer lifetime. In such case you can replace your battery, by simply ordering / buying a new battery for your mobile phone.

Hello, Leoch 12V battery, DJW12-12Ah, is no longer charging. We bought a John Deere riding toy at a local Toys R Us in Michigan three years ago. My children have only used it for two summers and is...


Sounds like a battery problem.
Lead acid batteries should to be charged every 3 or 4 months even if they are not being used, or they can slowly self-discharge and will start to deteriorate if the voltage drops below about 12.2v (for a 12v batt.)
They can then be difficult or impossible to charge. The charger can see this as fully charged and show green.
You can test for this if you have a voltmeter. You should be able to work out if it's the battery or a connection (or the charger).
Measure the battery voltage (use a DC voltage range greater than 12V). The normal voltages you should see:
A) Key off, no charger: >12v, <14
B) Key off, charger connected: >12, <14.2, but higher than A)
C) Key on, no charger: >12, <14, but lower than A)

If voltage A) is low and immediately goes high when the charger is connected then the battery needs replacing.
If A) and B) are exactly the same then it could be the charger is not connecting or is faulty. Measure the charger output, should be >13.8v (unless it's an "intelligent" charger in which case it might need some voltage applied to its output before it starts charging).

Note: If A) and B) are low, say <8v it's possible that an "intelligent" charger will refuse to start charging. In this case it's probably worth jumping the battery to a good 12v battery (e.g. car). Be very careful to connect the batteries (+) to (+) and (-) to (-). Leave connected for 10 - 20min or even overnight and then disconnect jumper leads and check A) and B) again. Sometimes a battery can be recovered by this method (it's unlikely to regain full capacity though).

My lenovo G550 appears not to charge when the charger is plugged in despite turning the mains power on and off to see if power is getting though and the blue neon light showing on the mains...


Hi m529,

I see you are having issues with you G550 charging.

You mentioned that the light on the charger is lit up but then it suddenly switches Off, and you also mentioned that the charge still has a light but the power is somewhat low despite of a fully lit up charger Light.

Have you tried draining the power from the system?

  • Remove the battery and the Charger or AC Adapter as well call it from the G550 then press and hold down the power button for 10-15 seconds to drain power from the system motherboard.
  • Once drained connect the AC adapter but do not connect the battery yet, then turn the Laptop ON to see if the system will power ON using the AC adapter/Charger if it powers up then there is no problem with the AC adapter/charger.
  • After testing the AC adapter if it is working power down the Laptop doing a normal shut down.
  • Once shut down or turned Off insert the Battery back in the Laptop then turn the Laptop ON using the battery only without the AC adapter/charger see if the system will turn ON using the Battery only.
  • If the Laptop powers On using the battery alone with out the AC adapter then the battery is most likely working as well on the issue.
  • Now power down the Laptop then connect the AC adapter to the Laptop with the Battery in the Laptop as well then turn the system ON again see if the problem will Occur again having the battery and the AC adapter/charger if the Problem happens with both Battery and AC adapter on the Laptop then the problem is the Motherboard, most probably the motherboard is having issues relaying power from the AC adapter to the battery and may be sent to the Depot for repairs.
I suggest that you call Lenovo for further information about your system, if you still have warranty and is still in the one year period then your system will be covered for any repairs needed - you can call @ 1 877 453 6686 for troubleshooting, you will be asked for a serial number Located underneath the Laptop on a small white sticker that states s/n meaning serial number.

I hope that this Helps.

Have a nice day,

A35 s1592 battery won;t charge


You probably have a problem with your power adapter. Since you mentioned that the battery discharges when connected to the adapter, it means that the charger is acting as a load instead of the other way around. This is a typical behavior of a defective charger.

Try to check the output of your adaptor using any voltmeter. The voltage reading should be approximately close to the voltage rating as printed at the back of your laptop. If not, then its wiser to buy a new ac adapter instead of sending it for repair to electronic shops. Most of these chargers are no longer reliable when repaired, and might cause more problem to the laptop instead.

Will not charge or turn on using USB cable.


Two things.

HTC phones will not charge from the USB port unless you have ActiveSync on an XP or Mobile Device Manager on a Vista PC loaded.

Second, if the phone has been stored for a very long time, 1 year if initially charged, 1/2 year if not, the the battery self discharges to a point the USB port PC Sync software doesn't know the phone is connected. You must jump start a charge on the battery by either and HTC AC charger, a generic AC/USB charger will not work, or you can apply a +5 VDC voltage to the power terminal, marked + and - on the battery case, on the two outside terminals I believe. This 5VDC must be current limited for safety. The Red and Black lead inside a standard USB cable will supply current limited +5 volts at 100MA. Chop off a standard USB cable, their cheap and break out expose the Red and Black leads. While connected to the PC USB port, hold the Red lead to the + battery terminal and the Black to the (-), or other outside terminal, of about 30 seconds to a minute.

Now when you plug the phone to the PC with a good USB, the Amber light on the phone to indicate Charging, may not come on for a while, 5 minutes or so, but it will eventually. If it does not, jump the battery again for a longer period of time.

An AC charger for the 3125 are fairly inexpensive. $7 or so, on ebay with shipping. This may be the way to go. Consider getting one with a new battery. They are sold this way sometimes and sometimes for little more that the charger alone.
